Arterial Speed Management with Control Measures: the Case of San Francisco, California
High vehicle speeds are strongly associated with both a greater likelihood of crash occurrence and more serious pedestrian injury. This study evaluated the effectiveness of traffic signal progression as a speed management tool in three arterial corridors in the city of San Francisco. Analysis of “before” and “after” field data on traffic volumes and speeds were used in the evaluation supplemented with estimates of air pollutant vehicle emissions. The findings show that the implemented control measure is an effective low-cost method to reduce the average speeds at the selected corridors. The revised signal settings timings also resulted in emissions reduction.
