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.
