TLDR

Impact of Sports Events on Local Traffic (5)What Redditors are Saying

Impact of Sports Events on Local Traffic

TL;DRSports events can have a significant impact on local traffic, especially before and after the event. Traffic congestion is often worse after the event as everyone tries to leave at the same time. It is recommended to avoid driving during peak times around the event to minimize delays. However, the level of impact can vary depending on factors such as the location of the event, the size of the event, and the road infrastructure in the area.

Traffic Patterns

The traffic patterns during sports events can be unpredictable. Before the event, traffic may not be significantly affected as people arrive at different times. However, after the event, traffic congestion can be severe as everyone tries to leave simultaneously [2:1]. This can result in hours-long traffic jams [2:1].

Timing Considerations

To plan your travel during a sports event, it is advisable to avoid driving during peak times, which are typically before and after the event. Leaving earlier or later than the rush can help minimize delays. Adding extra time to your travel plans, such as an additional 10 minutes or even an hour, can provide a buffer in case of unexpected traffic congestion [2:5].

Local Roads vs Highways

The impact of sports events on local traffic can vary depending on the location. While highways are more likely to experience heavy traffic due to people driving in for the event, local roads may be less affected. However, it's important to consider that local roads can still be congested if there are popular viewing spots or if there are multiple events happening in the area [2:2].

Unprecedented Events

It's worth noting that the impact of traffic during sports events can be difficult to predict, especially for unprecedented events. Factors like the popularity of the event, the presence of other concurrent events, and the availability of parking can all influence the level of traffic congestion. It's always a good idea to stay informed about any road closures or traffic advisories related to the event and plan accordingly [2:4].

Personal Experiences

Some users shared their personal experiences with traffic during sports events. One user mentioned that traffic was not too bad before the event but became congested afterward when everyone was trying to leave at the same time [2:1]. Another user suggested avoiding driving from noon to 9 pm to minimize traffic-related issues [2:5].

Impact of Sports Events on Local Traffic (19)ORIGINAL POST

Ive got an odd one:

Meraki MX95 running MX 18.107.10

For several clients on the LAN, the MX is dropping traffic after it ingresses the LAN interface. When PCAPing on the LAN interface, healthy, bi-directional traffic is observed (echo requests sent out the interface, valid echo replies from the client), however the MX shows 100% loss when pinging from the MX itself, and simultaneous PCAPs along the path show that the return traffic vanishes after the LAN interface capture when pinging from a remote host.

Other devices on the LAN (east-west) can communicate fine with the affected clients with no issue (pings, RDP, etc).

There are no firewall rules configured besides the default allow any-any, nothing in the event logs pertaining to the affected hosts, other clients in the same LAN work fine, PCAPs of successful vs failed traffic show no meaningful differences whatsoever. Support case is open, config has been validated, theyre scratching their heads too.

To add to the mystery- when using the ping function from the client specific page, it DOES see replies, but only when tested using that specific page. All other return traffic vanishes after it comes in the LAN interface.

8 sites with MXs (various sizes), full mesh, full meraki stacks at half of my locations, at this location (incidentally the only location in India) its an MX95, a bunch of MR-56s and some inherited Cisco sg300 switches in between, with a single flat LAN. The MX95 was installed about a month ago (replacing a Fortigate 100E), and this issue has existed since.

There is a point-to-point connecting the LAN to another facility (terminated directly to the MX LAN port 8), other clients on the other side of that P2P work fine, and east-west traffic to the affected hosts works fine, even between facilities (which requires the MX to switch the traffic t/from the P2P, with no issue).

Ive crawled the network front to back and no breadcrumbs indicating a problem, definitely nothing explaining why the captures see the traffic coming in the LAN interface then vanishing.

Its only affecting a handful of clients, and those are consistently impacted.

Ah ok. Hmm. When you look at route table do you have routes to the dst subnet when looking at the src mx? I suspect you do, since it works for some clients, but not all. I know its an odd question...

Is there any commonality between the clients that work vs don't?

Did someone accidentally apply a GP to those clients? :) I may or may not have seen it happen before...

Update: I was able to resolve the issue by changing the LAN from "VLANs" to "Single LAN"- while its great that traffic is flowing, it still doesnt answer the "WTF?" question, as all captures showed no issue whatsoever with vlan tagging or frame structure when compared against successful flows.

I have two separate sites with an HA pair of MX95's that are both experiencing similar issues you've described. All are running MX Firmware 18.107.2 . Unfortunately, we are already configured to route using a single LAN on the MX. -- We have a ticket open with Meraki Support.

I had an issue with I believe similar firmware version not same problem but the mx 95 was not allowing packets coming back in on outbound traffic initiated by our LAN it was only on devices with NATS and 210 whatever fixed it. was broke for a month or two before anyone noticed. On pcap it would just not show packets coming back or failed tls handshake.

Open a ticket and have the Meraki support do packet captures on the backend to confirm your issue. They might back you down or move you to 18.210.

  1. Open case in dashboard

  2. Call into Meraki support ( 1 (415) 937-6671 ) after case opened using opt 1, then case number

Please let us know what they come up with!

I do have a case open, and thus far other than confirming they see the same behavior in their captures, it has not borne fruit, although they are escalating internally. It was at their recommendation that I updated to 18.107.10 (from 18.107.2).

If you move to 18.210 (beta/rc) you might get over this by it enabling the multi-core support. It might introduce other issues but I would personally rather move up in code than back. It also provides some flexibility that you might need to tackle the issue.

Local driving day of eclipse?

Posted by laterthanlast · in r/Cleveland · 2 months ago

I know that traffic on the highway will be a mess the day of the eclipse because of people driving in for the event. How much do you think that will affect local driving? I’m planning to go over to a friends house for the eclipse - usually takes about 20 min to get there, avoiding highways. I’m trying to figure out how much time to leave myself - extra 10 min? Give it an hour to be safe? How much time are people building in to their local eclipse driving?

Update: the drive was totally fine and the eclipse was awesome 😁

No problem. Many people seem to forget that we are in a 150 mile wide “band” of totality that runs through most of the state and that it can be easily seen from anywhere that doesn’t have obstruction of the sky. I told one guy on here who was asking where to go and not to go to see it. I told him don’t stand in between tall buildings downtown or in the middle of the tree cover of the metro parks; and that he could go to one of thousands of parking lots off a highway exit to tailgate. I get people crowding downtown/waterfront for “events” just to make it more of a fun and memorable atmosphere for the eclipse, but my damn are some people just being silly. The waterfront/solstice steps in Lakewood are pointless. The sun won’t be out on the horizon and they will be looking away from the water based on positioning. Have fun and enjoy your time without worrying about or dealing with the crowds downtown or on the lakefront.

Based on the stories of people that drove to the last eclipse, traffic beforehand wasn't too bad, because everyone was arriving to their spots at different times. But afterwards, everyone was trying to leave at the exact same time, which caused hours-long traffic jams.

Fortigate 7.0.13 Traffic being treated as local traffic and blocked after upgrade

Posted by Salmify · in r/fortinet · 7 months ago

We Upgraded one of our Fortigate's to 7.0.13 last Friday, and since then some specific traffic is being processed as local traffic and blocked hitting "Policy 0". Prior to the upgrade was being forwarded and hitting a valid policy.

From my understanding the FortiGate is somehow seeing it as traffic destined to itself, and processing it as local traffic.

Any help or ideas are appreciated

Is the affected traffic destined to an IP Pool or VIP? Disabling ARP reply won't help if the traffic is still routed through the Fortigate, since it will still "see" it. There are a number of different scenarios on https://community.fortinet.com/t5/FortiGate/Technical-Tip-IP-pool-and-virtual-IP-behavior-changes-in-FortiOS/ta-p/277823 that you can look at to find if there is a workaround.

feroz_ftnt · 7 months ago

As you are aware, In FortiOS 7.0.13 and later, IP pools and VIPs are considered local IP addresses if responding to ARP requests on these external IP addresses is enabled (set arp-reply enable, by default). In this case, the FortiGate is considered a destination for those IP addresses and can receive reply traffic at the application layer successfully.

However, once an IP pool or VIP has been configured, even if it is never used in a firewall policy, FortiGate considers it as a local address and will not forward traffic based on the routing table.

The 'set arp-reply disable'is used in the case when IP addresses are overlapping with another device in the network. With arp-reply disabled, FortiGate should send an ARP request for the addresses defined in the VIP/IP pool if it needs to send traffic to units that own these IP addresses.

The 'set arp-reply enable'(default) command means that FortiGate will answer ARP requests for the IP address(es) mentioned in the VIP/IP pool.

Kindly verify for any overlapping SNAT for x.x.x.x and remove it if any , disable the unused IP pool and VIP, and verify the status.

IPsec Tunnel gets all the traffic (even local)

Posted by make_beer_not_war · in r/fortinet · 2 years ago

I have a 40F running 6.4.3. It has an IPsec tunnel to another FGT at a remote location. The IPsec tunnel interface is in an SD-WAN zone, and the default route is via the tunnel (all traffic reaches the internet via the tunnel).

There are a number of local interfaces on the 40F which should all be able to reach each other - a physical interface, 2 VLAN subinterfaces and the ssl.root interface.

The problem is that even local-to-local traffic is being routed via the IPSec tunnel. E.g. 10.10.44.5 on vlan 10 should be able to route to 10.100.44.103 on vlan 100, but instead the packets match the local-to-ipsec-vpn policy and are sent out of the tunnel interface.

The vlans and physical interface are all in a zone, with intrazone routing enabled. There is a policy allowing ssl vpn traffic to the local subnets and interfaces.

What have I overlooked to allow local subnets to communicate?

You mentioned you have a default route pointing to the IPsec tunnel. A default route is a viable route even for "local-to-local" traffic. Of course it will usually never be chosen, because you will have better routes for local destinations.

One way to override this is a policy route. If a policy route is configured to route any destination via the IPsec tunnel with the default route, this policy route will affect even that local-to-local traffic. This seems to be happening to you, based on your description.

Suggestions:
1, Review your policy routes, consider narrowing them a bit so that your local-to-local traffic doesn't match them. (you can do a negated destination=RFC1918, or something along those lines)
2, Consider tweaking your policies so that the local-to-local traffic isn't allowed to leave through the IPsec tunnel. (explicit deny on RFC1918 destinations, or similar)

Sounds like a misconfigured policy route… get router info routing-table all, and review the routes. Routing should be pointing the local vlans to the local interfaces, which won’t send it towards SDWAN, so your SDWAN rules won’t apply.

Does NordVPN reroute local network traffic?

Posted by kelemvor33 · in r/nordvpn · 1 year ago

Hi,

I have NordVPN on one computer in my house. However, I may replace that computer and move the software on it to another computer. This other computer is my Plex server. When I use Plex, I'm just streaming data within my network. The setup I may be going with would be something like:

  • Plex Server - Windows Computer with NordVPN
  • Media Storage - Synology device. Older device so will just be for media storage.
  • Plex Players - Fire Sticks and Laptops

If I have Nord on the Plex server, will that have any effect on my ability to stream the videos within my network or does Nord only affect traffic that goes out to the internet?

With the new setup, my Plex server would potentially also run Sonarr, uTorrent, etc so I need it to be behind VPN. Maybe I could use Split Tunneling and exempt Plex from Nord?

Just looking for advice on how to best set this up.

Thanks

Commercial VPN's are for internet traffic, they don't control your local network traffic. It just makes a simple encrypted point-to-point connection between the client (your computer) and the VPN server (Nord in this case) and from there it is directed outward to the internet without VPN.

For the local network there is a setting for "Invisibility on LAN". With that disabled you should be able to see your Plex server.

However some people have reported varying levels of success with it and also with the split-tunneling feature on the Windows app.

There is no split tunneling built into the Linux app, but the whitelist works fine.

I believe, by default, it blocks local traffic. I think if you have a local server, you need to customize to get access (like with split tunneling). But I'm not 100% sure. I usually just disable the VPN when I need local access.

Video surveillance system LAN impact

Posted by _ReeX_ · in r/networking · 1 year ago

Greetings, fellow Redditors! We are in the planning phase for a new school site and looking to establish both LAN infrastructure and a video surveillance system.

It's worth noting that the regular network traffic at the new K-12 school site (600 students, 100 staff, 250 Chromebooks, 80 Windows laptops ,couple virtualised Windows Servers, 20 printers, 8 MFC, up to 200 smartphones, PBX with a dozen DECT units only for staffrooms) will primarily consist of internet-bound activities utilizing a 1 Gbps symmetric connection. The majority of data transfers will be directed towards the internet, while a smaller portion will be allocated for local traffic, such as printing tasks and access to a limited number of local resources on the file server, if necessary.

The proposed video surveillance system will comprise 55 Poe cameras, with each camera potentially requiring up to 10 Mb/s bandwidth to the local recording server (550 Mb/s) and monitoring workstation. As we consider the impact on the LAN, we would appreciate any insights or experiences you can share.

Switches are planned to be stacked and interconnected to MDF through 10 Gb/s fiber links.

I am enclosing a rough rack ports count, which includes a full option (all wall ports connected to switches) and a minimum option (all cables connected to patch panels, but only required ports effectively connected to switches, to lower initial number of required switches).

https://i.ibb.co/kgKRzzH/Screenshot-6.png

We are curious about determining if dedicated appliances are necessary to effectively manage the network load. Your expertise and suggestions are highly valued. Thank you!

Yes, unless your internet traffic starts saturating the 10 gig links. Highly unlikely. Depending on what you consider to be more important you could setup QOS to guarantee a certain amount of bandwidth be available at all times for cctv. In reality it will probably work fine forever separating the traffic on two different vlans and calling it a day.

With 10Gb links between switches I see no problem here. Depending on cameras and their distribution across switches, you'll need to watch your POE power budget carefully. Mid-span high power injectors might be a need/pragmatic solution.

Does all local traffic go through the main router?

Posted by obvi-Ruth-Irish-TBH · in r/GoogleWiFi · 3 years ago

I use an antenna and a digital tuner (HDHomeRun) to watch most live TV. I'm trying to understand how the feed gets from the digital tuner to the various devices that I view it on. All of the devices are on my network. The main thing I am trying to figure out is if all the traffic will always go back through the main router or if it is possible to just for through a wifi point, but I am also just trying to get a better understanding overall of how local traffic works.

Below area few hypothetical scenarios. For each one, would the traffic go from Tuner -> Point A -> Client, or would it go from Tuner -> Point A -> Router -> Point A -> Client. For each scenario lets assume that the Tuner and Client have a significantly stronger connection to Point A than they do to the main router (i.e. they are connected to Point A). While thats not what will happen in reality, I think it makes the scenarios simpler.

Scenario 1: Tuner and Client are both on WiFi (Note: HDHomeRun doesn't actually have WiFi, but this is hypothetical) and Point A is a Nest Wifi Point

Scenario 2: Tuner is hardwired to Point A, Client is on WiFi, and Point A is a Nest Router that is being used as a point.

Scenario 3: Point A is a Nest Router that is being used as a point. It has an Ethernet switch wired to it. Tuner and Client are hard wired to the switch. This scenario is a little different because of the switch. In this scenario does the traffic even flow to the switch or would it go from Tuner -> Switch -> Client?

Thanks!

The hdhomerun tuner is connected to your network via a hardwired connection. No matter what which scenario, main router, access point, switch. That traffic will be routed through your network through your router and to the device that needs it. Or at least that is how I understand home networking in my limited knowledge.

In scenario 3 it will certainly not go to the main router: it will just go tuner > switch > client.

I'm not sure about the others.

I also have an HDHomeRun in my house. I can't find the source but Google Wifi tends to route traffic across the least amount of hops. If your Tuner and Client are using the same Nest Point, it routes internally. However, which points clients connect to is determined by each client independently. If your Tuner is connected to the Nest Router and the Client is on Point A, traffic would flow through both the router and point.

This counts for connecting Wifi Points together as well; if Point A can see the router weakly and Point B is between Point A and the router, Point A will still use the weak connection in order to minimize the number of hops. It will only connect to Point B if it cannot see the router at all.

For your examples...

Scenario 1 depends on which wifi points each device is connected to...

...if the same point/router, it would go Tuner -> [Wifi] -> Nest Point/Router -> [Wifi] -> Client

... if different points, it would go Tuner -> [Wifi] -> Nest Point/Router -> [Wifi] -> Nest Point/Router -> [Wifi] -> Client

Scenario 2 would be Tuner -> [Ethernet] -> Point A -> [Wifi] -> Client

Scenario 3 would be Tuner -> [Ethernet] -> Switch -> [Ethernet] -> Client

I wrote out the medium in use (Wifi, Ethernet) because it helps visualize the complexity of traffic flow. Scenario 2 and 3 are functionally the same, but because Scenario 2 changes mediums, it's slower than Scenario 3. Ethernet (wired) connections are always the fastest which makes Scenario 3 the best; traffic routes through the switch only.

Add certificate to server - will that impact/interrupt existing non-encrypted traffic?

Posted by Mvalpreda · in r/SQLServer · 1 year ago

Looking to add a certificate to our SQL server for inbound communication from a vendor. We still have a lot of unencrypted (local) traffic to SQL, so I want to make sure that is not impacted. The direction at read at Microsoft make it sound like once I make the change encryption is forced and would (I'm guessing/assuming) break my existing traffic.

  1. In SQL Server Configuration Manager, expand SQL Server Network Configuration, right-click Protocols for , and then select Properties.

  2. On the Flags tab, in the ForceEncryption box, select Yes, and then select OK to close the dialog box.

  3. Restart the SQL Server service.

Can I have it both ways?

If you opt to force encryption then yes, any client that can't handle encrypted traffic, and any client that doesn't recognize the CA that issued your certificate, will be unable to connect.

You can have a certificate and not force traffic to be encrypted.

I have a legit cert issued by GoDaddy.....so that part won't be an issue.

Can I have encrypted traffic to SQL by just adding the cert while leaving the rest of the traffic untouched?

Until you discover an ancient app that can't handle TLS 1.2 encryption at all.

Can I have encrypted traffic to SQL by just adding the cert while leaving the rest of the traffic untouched?

I don't understand what you mean by this.

If you do not set Force Encryption, you can add the cert (and then restart the service) and clients which support encryption and "ask" for it when establishing the connection will get encrypted traffic. Clients which do not ask for an encrypted connection will not get encrypted traffic.

If you do set Force Encryption, then the server will require that all clients encrypt traffic, regardless of the settings used to establish the connection. If a client that doesn't support encryption attempts to connect, it will ultimately fail.

A relevant article for you:

Full disclosure: I had to read it multiple times because it's the opposite of straightforward. MS managed to make this way more complicated than needed, as is their M.O.

They like to do stuff like drop a major security change in a minor version update without giving any heads-up. Simultaneously they somehow deprecate things but never remove them so everything is backwards compatible. The duality of MS.

P2P traffic on “local network”

Posted by New_Astronomer_735 · in r/MicrosoftTeams · 5 months ago

Hi,

Noticing occasionally that users are sending some UDP >50000 directly to each other. Not only on the same LAN, but also cross office or even home users on VPN towards office users. This traffic is blocked by firewalls.

What is the impact of this traffic getting blocked. Does it impact user experience? Is this a feature which can be turned off?

Teams reused Skypes candidate list algorithm. It tries to negotiate shortest path for peer to peer calls. It will fail back to a path that is unblocked without too much loss.

Audio, Video, Screen sharing for 1:1 calls will always try to negotiate the shortest path (P2P). If you are blocking these P2P communications, then everything will likely flow through Teams via the internet (which is inefficient). If there is more than 3 people in a call, then all traffic will go to Teams as it does for all meetings.

Official recommendation is to split-tunnel VPN for Teams traffic

How does sports/culture affect urban planning?

Posted by ToastedTaco · in r/urbanplanning · 1 year ago

Hi all. I have been wondering how a city culture, specifically sports, affects urban planning.Elements such as stadiums, traffic flow, transportation all affect a city’s urban planning, but to what extent?Does a “sports town” have any advantages over a city that does not? How does it affect population vs tourism?Just some wandering questions I have pondering this idea. Would love to hear everyone’s thoughts!

Stadiums in North America usually have huge parking footprints. There is an ugly history of this damaging the urban fabric as new, larger stadia get constructed and require demolition of the neighborhoods around them. There are many case studies to look at which illustrate this.

The newer trend in baseball has been a "retro revival" with smaller parks that fit into and reflect their neighborhood, learning from how old parks like Fenway had to do weird stuff to fit on a small urban lot but eventually it became part of their charm. It's obviously better for the surrounding city, but I think it makes for better ballparks, too.

IMO there's a good argument for putting stadiums downtown. The transportation problem of how to get tens of thousands of people in and out of a small area is the same one that city centers have already invested in solving in planning for rush hour commuters. Being able to reuse transit infrastructure that way in off hours is quite practical.

The balance works out best for baseball (80 home games a year) and basketball/hockey arenas (40); NFL teams only have 8 home games and their stadiums have larger footprints so it's a worse use of urban land.

Charlotte’s NFL, NBA, and minor league baseball stadiums are downtown with extremely limited parking and it’s been fine. I grew up 45 minutes away and never had problem’s finding parking growing up.

Plus it was a draw to go to games even when the teams stunk because after the game you had the the whole downtown to hangout (21-25 were wild years)

I just want to clarify that, while this is true in the US, Sports cities and their stadiums are far from this: they frequently have little if any parking footprint, are located on sometimes multiple urban public transit lines and sometimes on inter city lines.

In fact, you can - in the US - actually trace this to specific sports. MLS, NBA, MLB, and NHL actually prefer stadiums on transit (see climate pledge in Seattle), that understand that the following is moving towards a younger fanbase and that's there's more money in building a vibrant neighborhood around a community centric stadium (and cashing in on the real estate instead of parking).

NFL has a disproportionately large suburban fanbase, which results in larger current needs for parking, which is why SoFi looks like it does.

One of the best planned areas for sports in the US is the downtown Cincinnati riverfront areas. The two stadiums (Great American Ballpark & Paul Brown Stadium) were originally your standard parking lot wastelands, and the freeway there still sucks, but the recent wave of trendy mixed use development as well as the streetcar addition to the city makes it a great place to spend time. There is transit access, great walkability, tons of bars and restaurants, a riverfront park with a mixed-use cycling/walking. The people who want to bring their buses and trucks and tailgate can still do so thanks to the industrial district nearby being a parking area for weekends. Compare that to stadiums like Kansas City or Dallas where the football stadiums are just dwarfed by their surrounding parking? Cincinnati did things well.

I have this fear that if the stadium's built someone would build a parking garage on the 8th & Market surface lot, then it'll never be properly developed. Idk how likely that'd be, but I'm a pessimist in development matters.

I think that downtown San Diego is oddly a good example of sports infrastructure affecting urban planning, despite San Diego historically not being a “sports town.”

The San Diego Padres and San Diego Chargers used to play at the same location in Mission Valley (Qualcomm Stadium, née Jack Murphy Stadium) until 2004 when the Padres moved to Petco Park just a few miles south in downtown’s East Village. At the time downtown was not a nice area and the ballpark completely revitalized the neighborhood as was its intent, with dozens of high rise condos, apartment buildings, schools, and businesses built in its wake. (ETA: you can see in the photo how the ballpark incorporate the existing brick building on the left hand side of the top photo. The Western Metal Supply Co building was moved a block and rotated 90° to be included as seating/suites in the bottom image, seen at the bottom left corner of the jumbrotron displaying SD, with three stories of white balcony seating coming off the side). The transit system is incredibly subpar but the ballpark is connected on our trolley line and there is also not a lot (actually, there is “a lot” as in a single surface street parking lot specially for tailgating, and maybe one dedicated parking garage?) of parking associated with the ballpark that you would normally see with a sports complex.

Sports cities bring in some serious economic contributions to their local economy when they get some of the cooler sporting events.

I’ve done a few major sporting event planning for a municipality, the event knew what to do and what was expected. The events were college based but still massive. Definitely will Heavily impact tourism but is dependent on teams playing.

Traffic wise, police take care of that. The event I did submitted like 8 months in advance.

how do sports events affect local traffic

Here are a few key considerations

  1. Event Size and Location: The impact of sports events on local traffic can vary depending on the size of the event and its location. Major events like championships or playoffs tend to attract larger crowds and have a more significant impact on traffic.

  2. Timing and Schedule: The timing of the event can greatly affect traffic. Evening events during rush hour can cause heavier congestion, while daytime events may impact traffic during regular business hours. Additionally, multiple events happening simultaneously in the same area can compound traffic issues.

  3. Venue Accessibility and Parking: The accessibility of the sports venue and the availability of parking can influence traffic congestion. Venues with limited parking options may result in more vehicles searching for parking spaces, leading to increased traffic in the surrounding area.

  4. Public Transportation: The availability and usage of public transportation can impact traffic. If a sports event encourages attendees to use public transportation, it can help alleviate traffic congestion. However, if public transportation options are limited, more people may rely on private vehicles, contributing to increased traffic.

  5. Local Road Infrastructure: The capacity and efficiency of local road infrastructure play a significant role in traffic impact. Well-designed road systems with multiple entry and exit points near the venue can help distribute traffic flow more effectively.

Takeaway: Sports events can have a noticeable impact on local traffic, especially during major events or when held in densely populated areas. It's important for event organizers and local authorities to plan and communicate traffic management strategies, encourage the use of public transportation, and provide alternative routes to minimize disruptions and congestion.
