Abstract:
All Pedestrian accidents in Sri Lanka in last four years from 2010 to 2013 are 20.89%,
17.65%, 17.53% and 18.51% of total accidents respectively. Among these, pedestrian
crossing accidents are 17.89%, 15.20%, 17.85% and 18.17% respectively. In which, midblock
pedestrian crossing accidents are 81.88%, 79.56%, 81.20% and 77.08%. Thus, midblock
pedestrian crossing accidents are more than 75% of the pedestrian crossing
accidents. This study focus on identifying factors that have contributed to such high
numbers of accidents such as the design of road and vehicle, factors affecting pedestrian
crossings visibility and attitude of drivers and pedestrians. The method used to evaluate this
is quantitative, which analyses mid-block pedestrian crossing accidents for four hundred
kilometers from A03, A12, A09 and A20 roads and interview of hundred drivers and
pedestrians.
At presents 40% of the ‘A’ Class roads in Sri Lanka have wider and asphalted pavements.
Maximum allowed speed in these roads is 70 km/hr. Most of the vehicles at present are in
good condition than that of in the past. Speed control mechanisms are not strictly followed in
Sri Lanka compared to developed countries. Thus, 70% of the interviewed drivers drive more
than allowed speed. Therefore, they face difficulties to control speed in Pedestrian crossing.
In this research, 100% of the pedestrian crossing constructions are not suitable for
handicapped people and 65% haven’t proper stud and material. Based on interviewed data,
50% of the drivers and 45% of pedestrians do not use pedestrian crossing properly. Due to
the head and dim light elimination, visibility of pedestrian crossing is affected. Some of the
vehicles such as three wheelers head light brightness is higher that of other vehicles. This
also affects the visibility of pedestrian crossing. 10% sign boards in my research are not
constructed in proper location. Visibility of these signboards is affected by obstacles such as
trees and poles. 15% pedestrian crossing visibility is affected by sag, crest and super
elevation. White colour road markings visibility is higher at night than yellow colour markings
used for pedestrian markings.

The results indicate that mid-block pedestrian crossings accidents are influenced by
combination of design of road and vehicles, factors affecting visibility of pedestrian crossings
and attitude of pedestrian and drivers.
