BUS LINKED PRIORITY IN SIGNALLING SYSTEMS

The paper shows how buses can fail to benefit from standard transyt traffic signal timings and shows how this can be remedied using bus transyt signal plans. Although bus transyt calculates signal plans in the same manner as transyt, it needs more data to describe separately the movement of buses from other traffic. This additional information needed includes bus routes, bus flows, bus speeds, and average time spent at each stop. From tests carried out using bus transyt in Glasgow bus speeds were increased by 9%, 8% and 7% during morning peak, off-peak and evening peak periods compared with speeds under standard transyt timings. /TRRL/
