VARIATION OF HEADWAYS AT SIGNALIZED ARTERIALS WITH RESPECT TO DISTANCE AND CYCLE TIMES

In this study, the variation in the proportion of free vehicles at a signalized arterial is tried to be modeled with respect to distance and green/cycle time ratio. in the analysis, it is assumed that headways between vehicles can be defined with cowan m3 distribution. from the analysis, proportion of free vehicles in the left lane of an arterial is lower than other lanes. this results indicates that, left lanes are occupied by higher vehicle volumes. the analysis also showed that, proportion free vehicles increase with respect to the distance to traffic signals as expected.
