Abstract

The city of Delhi had more than 1,900 traffic fatalities in 1993. Delhi police firsthand information reports show that most of these fatalities involved heavy vehicles striking pedestrians and bicyclists at midblock locations.

RESULTS reveal that Delhi has many nonmotorized traffic entity fatalities given its degree of traffic homogeneity and total traffic fatalities as compared with other places in the world. To find heterogeneous traffic characteristics that may significantly enhance traffic safety and operations, a heterogeneous traffic conflict study for 14 Delhi midblock sites followed. The sites ranged from ones with many fatalities to one with none. To evaluate the association between heterogeneous conflict rates at each site and respective site fatalities, a Spearman rank correlation produced a measure. A positive correlation of 0.14 exists between conflict rates and fatalities for all traffic entities.
