Bus Delay Investigations along the Upstream Bus Bay at Signalized Intersections

Abstract

Bus bay stops at signal-controlled intersections may cause greater delays compared to on-line bus stops. By using a traffic flow model and wave theory, this study established the delay model to estimate the bus delay in bus bay stops at a non-saturated signalized intersection to provide the mathematical expressions of bus delays. The results show that bus delays along bus bays are closely related to signal timing scenarios, traffic flow characteristics, as well as arrival and service features of buses.
