Abstract:
Road crashes in Sri Lanka is becoming a major social, economic and health issue with
rapidly increasing number of vehicles, road kilometers and vehicle kilometers travelled.
Despite the significant increase in road infrastructure development in recent years (post war
period), number of pedestrian related accidents remains at a very significant level. One of
the reasons is not having due attention towards the pedestrian related infrastructure
development such as pedestrian walkways, safe pedestrian crossings and safe and efficient
public transport services, etc.
As a result, the probability of a pedestrian being exposed to unsafe road conditions has been
increased giving way to the increased risk of pedestrian casualties from road crashes.
Adverse effects of this were evident with comparatively higher number of pedestrian
casualties all over the country. The impacts of these crashes are comparatively high due to
the higher probability of these crashes being a fatal or grievous than other types of crashes.
In the year 2013, 7004 pedestrian casualties were recorded while 10% of them being fatal
making it the highest rate of fatalities from all the categories of casualty.
In parallel to the aged friendly city concept introduced in Moneragala District and considering
severity of the problem of pedestrian crashes that affect elderly and disabled significantly, a
case study was conducted to assess and find out the contributory factors caused by the
deficiencies of roadway conditions towards pedestrian crashes in Sri Lanka taking
Monaragala, Buttala and Wellawaya DS divisions. Total accidents and pedestrian related
accident details for the past decade (2004-2013) in these areas were extracted from ‘Sri
Lanka Police Accident Database’ and analyzed using descriptive statistics. The existence of
a relationship between all crashes and pedestrian related crashes were checked using chisquare test. Spatial distribution of pedestrian related crashes within the study areas was
analyzed to find out hot spots for pedestrian crashes and then a site visit was made for those
locations to collect information about the background.
It was found that less than 6% of the pedestrian related crashes occurred at junctions where
limited pedestrian facilities are available while the rest of the crashes have occurred in midblock sections (road stretches with no intersection within 10m). More than 55% of these
crashes have taken place where there is ‘no pedestrian crossing within 50m’ or ‘on road
without side walk’ depicting the inadequacy of pedestrian related infrastructure. Population
wise, the portions of elderly people (age >= 60 years) and young people (age <= 14 years)
within these three divisions are 9% and 27% consecutively and the pedestrian crash
involvement of the above age categories are 15% and 20% respectively. The elderly people
had significantly higher percentages of crash involvements than the elderly population
proportion (9%) at locations where ‘no pedestrian crossing within 50m’ (19%) and at ‘roads
without sidewalks’ (15%) in rural conditions. This points out the fact that elderly people are
more susceptible for crashes especially at locations in rural condition. Site visits for the fatal
pedestrian crash hot spots revealed mainly poor visibility due to geometric constraints such
as sharp bends, rolling terrain (change in vertical alignment) and unavailability of pedestrian
walkway nor enough hard shoulder compelling pedestrians to occupy carriageway increased
the risk for pedestrian related crashes
