DEVELOPMENT OF CRITERIA FOR PROVISION OF PEDESTRIAN CROSSING FACILITIES

Abstract

Walking is an important transportation mode. Everybody walks at some point of time and it is also a critical link in everyday life for many people. While crossing the road, the pedestrians reject many vehicle gaps before finding a suitable gap. In the case of multi-lane or dual lane carriageways. the lane wise distribution of accepted and rejected gaps plays a key. This also gel afkcted by the arrival rate of vehicles, the delay caused to the pedestrian due to vehicular now and the total waiting time at kerb or a median . Following are the different types olroad layouts where pedestrian crossing may be necessary in Indian conditions: 2L- 2Way with median. 21.- 2Way without median, 4L- I Way without median, 41- 2Way with median. 41-2\Vay without median, 61.- 1 Way without median, 61- 2Way with median. Different types of crossing flicilities can be provided in such conditions. 'l'hcsc can be zebra crossing, signalised or segregated (over bridge or underground). It was found that IRC-103 (2012) is deficient in defining clearly the provision of crossing facility. It uses 1-1CM model for the same. This work is an anempt to suggest a criterion for the provision of pedestrian crossing facilities for Indian traffic conditions. Pedestrian crossing data were recorded in Jaipur. The extracted data included waiting time for the pedestrian at kerb, gaps accepted and rejected by the pedestrian in each lane, waiting time at each lane, waiting time at median, pedestrian now and vehicular flow at 5 minutes interval. The lane wise variations of crossing time and crossing speed are studied. Critical gap was calculated for every lane at each site. The pedestrian crossing time and waiting time were used for calculating pedestrian delay. Cluster analysis was done to segregate the data on delay. vehicular now and crossing time for deciding the type of pedestrian facility to be provided at a mid-block road section.
