SAN FRANCISCO MUNICIPAL TRANSPORTATION AGENCY
Target: 5.8 collisions per 100,000 miles
Result: 5.8 collisions per 100,000 miles
This metric measures the ratio of Muni collisions to every 100,000 miles of Muni service. Measuring Muni collisions per 100,000 miles enables San Francisco Municipal Transportation Agency (SFMTA) to view collisions across the wide variety of vehicles in its fleet. Collision reporting is a key performance indicator for the SFMTA’s strategic objective to create a safer transportation experience for everyone.
HOW THE SAN FRANCISCO MUNICIPAL TRANSPORTATION AGENCY IS PERFORMING
In April 2015, SFMTA introduced the Collision Reduction Program that laid out a multi-faceted approach to address this increase. Some key features of this program include changes to training, post-collision review, and coordination among operators, management, and street operations support teams. New operators undergo follow-up training at monthly intervals for the first six months of service to build and reinforce safe driving habits. All operators undergo retraining, regardless of the length of their service, following an avoidable collision. The SFMTA also launched the STOP (Stop, Think, Observe, Proceed) awareness campaign in June 2016 to encourage Muni operators to continuously scan for road hazards.
In fiscal year 2017-18, the SFMTA's Transit Division created the Collision Reduction & Safety Implementation Team. This team's primary function is to develop and evaluate mitigating measures after a collision, analyze collision trends, and develop proactive measures to reduce potential future collisions. Through a data-driven process, the team has implemented improvements that are expected to reduce future transit collisions.
While overall Muni collisions have had increasing long-term trend, capital projects have been successful in reducing collisions on specific corridors, such as the 14 Mission Rapid Project, where collisions have been reduced by nearly 85% since the project was implemented. That project is part of Muni Forward, the SFMTA’s program of service changes and transit priority street projects, which includes a series of projects at high-collision intersections aimed at improving safety as well as transit reliability. Muni Forward projects are applying best practices in transportation engineering across the system to reduce transit delay and increase safety. Improvements such as curb extensions at bus stops will save time for transit riders and avoid the need for buses to pull in-and-out of moving traffic. Reducing the frequency of Muni buses pulling in and out of traffic and providing more miles of wider, dedicated transit lanes should reduce collision rates.
How Performance is Measured
Data on Muni collisions are reported through the TransitSafe system and calculated as a ratio to every 100,000 vehicle miles traveled, as reported by the Muni asset management database.
