Variation of the Start-Up Time of Pedestrians with Their Familiarity to the Signal Phase

Abstract

In allocating green time for pedestrians’ signal phase, most of the signal time calculations are paying attention only towards the time taken by pedestrians to traverse the crosswalk. But it may result in dangerous situations caused by pedestrian-vehicle interactions. Therefore to improve safety, consideration on the start-up time of pedestrians is important. Also the start-up time may vary with the familiarity of the pedestrians to signal phase. This research was carried out in order to find how the start-up times vary when pedestrians are familiar with the signal phase and when they are not. Data were collected at selected locations and graphical interpretation was done to find the mean and the standard deviation. Then a hypothetical test was carried to find the significance of start-up time values at different locations. Final results showed that the start-up time is highly significantly different when pedestrians are familiar with the signal phase and when they are not.
