"Yesterday's power outage was a widespread event that caused gridlock across San Francisco, with non-functioning traffic signals and transit disruptions."

Transit Signal Priority (TSP) helps buses get through traffic signals more efficiently by holding green lights or shortening red ones when a bus is approaching. Until now, most systems worked best for far-side stops, where buses stop after passing through an intersection. However, many transit agencies prefer near-side stops because they give drivers better visibility and reduce the need for passengers to cross in front of traffic. However, these safer configurations make it harder for signal systems to give the bus priority effectively.1
