Saturation flow at a signalised intersection approach with a downstream bus stop and bicycle lane

As the demand for transit service rises, buses are more prevalent on roadways; hence, it is important to evaluate the impact of transit buses on the local traffic stream. This research employed a novel methodology to study the influence of offline bus stops on traffic flow rate at signalised intersections. The re-entry process of stopping buses at signalised intersections causes impact on general traffic flow. In the past, no study has been analysed the impact of a downstream, offline bus stop with adjacent bicycle lane upon traffic flow rate across the stop line at a signalised intersection. Data analysis confirmed that re-entering buses impacted the general traffic flow across the stop line more than the other events analysed. However, traffic flow returned to steady state after the second car crossed the stop line. An adjustment factor to traffic flow rate was developed to reflect the impact of the re-entering buses of the far-side off line bus stops at signalised intersections
