Abstract:
Pedestrian accommodation should be an integral part of the design of any
transport infrastructure project. It can be defined as walkways and pedestrian
crossings Pedestrian have a right to cross roads safely. Therefore road designers
have a professional responsibility to plan, design and provide safe walking and
crossing facilities.
Recent accident studies identified that pedestrian comprise a significant
proportion of serious injuries and fatalities while they were crossing the road
without using a marked pedestrian crossing. As the majority of pedestrian accident
occur while crossing a road, the need of safe and efficient pedestrian crossing
facilities could be the most important pedestrian safety factor.
Sight distance, Level of Service and delay to pedestrian are major terms to be
considered with warrants prior to installation of pedestrian crossing at a location
of road being considered.
Some time there would be additional delay and hazard by introducing crossing
where it is not needed or is not suitable.
Pedestrian characteristics and travel behaviour in the form of relationships among
parameters such as speed, density, flow and space of pedestrian need to be
identified by conducting further pedestrian surveys such as flow and travel time
Design of a pedestrian crossing requires a basic understanding of related human
characteristics and capabilities which are dependent on age, physical and mental
condition of pedestrians, who are expected to use the crossing at that particular
location.
So the main aim of this study is to develop a guideline to assist in determining the
appropriate crossing facility for a given location of a road based on the sight
distance, Level of Service, delay to pedestrians and vehicles, pedestrian speed,
density, flow and space in addition to the warrants.
