What are the best traffic management strategies for special events?

1 Identify the traffic demand

The first step in planning for a special event is to estimate the traffic demand that it will generate, both in terms of volume and mode. This requires analyzing the characteristics of the event, such as its location, duration, capacity, schedule, and target audience. It also involves collecting data on the existing traffic conditions, such as the road network, public transit, parking, bicycle and pedestrian facilities, and travel patterns. Based on this information, transportation planners can forecast the expected number and distribution of vehicles, transit riders, cyclists, and pedestrians that will travel to and from the event.

2 Design the traffic control plan

The next step is to design a traffic control plan that will optimize the traffic flow and safety around the event site. This may include installing temporary signs, signals, barriers, cones, or other devices to regulate the traffic movements and directions. It may also involve modifying the existing traffic control devices, such as adjusting the signal timings, phasing, or coordination, or changing the lane configurations or turn restrictions. The traffic control plan should be coordinated with the event organizers, the police, the fire department, and other emergency services, to ensure a smooth and secure operation.

3 Provide the travel options

Another important strategy is to provide a variety of travel options for the event attendees, to reduce the reliance on private vehicles and the demand for parking. This may include enhancing the public transit service, such as adding more buses, trains, or shuttles, or offering special fares, passes, or incentives. It may also include promoting the active transportation modes, such as providing bike racks, bike valet, or bike share stations, or creating temporary bike lanes or paths. Additionally, it may include encouraging the use of ridesharing, carpooling, or taxis, by creating designated pick-up and drop-off zones or partnering with service providers.

4 Communicate the travel information

A key factor for a successful traffic management is to communicate the relevant travel information to the event attendees and the general public, before and during the event. This may include disseminating the traffic control plan, the travel options, the parking locations and fees, the road closures and detours, and the expected delays and congestion. The communication channels may include the event website, social media, flyers, posters, radio, television, or mobile apps. Moreover, it may include providing real-time updates and feedback, such as using variable message signs, traffic cameras, or sensors.

5 Monitor and evaluate the traffic performance

The final step is to monitor and evaluate the traffic performance during and after the event, to assess the effectiveness of the traffic management strategies and identify any issues or areas for improvement. This may include collecting data on the traffic volumes, speeds, delays, accidents, or incidents, using manual or automated methods. It may also include soliciting feedback from the event attendees, the event organizers, the traffic control staff, and the stakeholders, using surveys, interviews, or focus groups. Based on the data and feedback, transportation planners can report the results and recommend the best practices for future events.
