PROJECT

Arrowhead Stadium Traffic Study

A typical Kansas City Chiefs home football game draws more than 70,000 fans and 22,000 vehicles. Our team conducted a traffic study at Arrowhead Stadium to analyze the ingress and egress of vehicles and pedestrians on game days and to propose upgrades to enhance the fan experience.

The study team identified ingress and egress pinch points and developed solutions to alleviate or eliminate them. The work entailed performing a high-level review of adjacent intersections maintained by the City of Kansas City, Missouri, and the Missouri Department of Transportation (MoDOT).

In evaluating the adjacent roadway network and operations at specific intersections, our team recorded in-person observations of operations, along with Google traffic data. We identified and measured vehicle queues, as well as vehicle and pedestrian conflict points. The study’s recommendations for site and adjacent intersection improvements were categorized as on-site or off-site, and data was gathered about responsible parties, advantages and disadvantages.

During game egress, we identified the most acute traffic capacity point for each gate. The critical points were often where two lanes merge to one or at an intersection. Unless capacity was increased at these downstream points, no upstream capacity improvements would increase capacity at the gate.

Due to the dynamic nature of the traffic and the large footprint of the stadium site, traffic engineering services included both in-person data collection and video from security cameras. The team also used StreetLight Data, a transportation analytics source, to provide a holistic analysis of where fans were traveling to and from.

A separate pedestrian study — incorporating data collection efforts and an examination of the Lot L pedestrian bridge — included capturing video data after a game to assess behavioral trends when the pedestrian bridge capacity was overwhelmed. The study focused on identifying updates to increase pedestrian flow and discourage unsafe pedestrian behavior.
