An Overlapping Phase Approach to Optimize Bus Signal Priority Control under Two-Way Signal Coordination on Urban Arterials

With the consideration of uneven traffic volume distribution at intersections on urban arterials, this paper aims to minimize overall passenger delay (buses and private vehicles) identify applicable conditions proposed method with field data. The overlapping phase-based signal control logic bus priority algorithm under two-way coordination arterial roads are proposed. vehicular capacities occupancies for buses cars considered in evaluation performance. A test was carried out two major an road Hefei, China. data, is examined possible influencing factors analyzed identifying corresponding conditions. analysis result shows that application phase helps provide a relatively flexible varying demands intersections. Compared conventional phase, it isof more practical significance consider apply bussignal according condition volumedistribution arterials. can effectively decrease total arterials certain applicability identified as well. It verified coordination, based phases, conducive improving efficiency Regarding method, results show not all situations decreasing should be applied principles order efficiently improve roads.
