Identifying the most suitable road crossing infrastructure based on estimated delay to pedestrians and vehicle users

Abstract Worldwide guidelines have been studied to identify the most common parameters being considered for making a decision regarding identification of most suitable road crossing infrastructure. Delay being the most common parameter needs to be considered to make a decision regarding most suitable crossing infrastructure. This study proposes a methodology to select road crossing infrastructure type based on the delay caused to pedestrians and vehicle passengers. To estimate the average delay caused to pedestrians and vehicle users, data through videography have been collected at six locations in Delhi. At all six locations, average delay caused to pedestrians and vehicles users has been estimated using existing methods suitable for Indian traffic conditions and behavior. Total delay caused to all pedestrians and vehicle users has been calculated based on average delay, traffic volume count and number of pedestrians. Estimated gross delay for all users (total delay of pedestrians and vehicle users) for alternate road crossing infrastructures (at-grade signalized and grade-separated) has been compared to identify the one which causes minimum gross delay. Total delay has been compared for various scenarios developed considering the equal and higher priority for non-motorized and public transport users compared to personalized vehicle users.
