Using GIS to Identify Bus-stops with high levels of pedestrian involved accidents




       Most pedestrian involved accidents are due to the lack of the appropriate choice of bus stops locations. Some bus stops are not safe because the locations do not have adequate safety feature such as cross-walks to cross the streets; so, pedestrians cross the streets from either behind or in front of the buses, resulting in injury, death. This paper discuses the importance of geographic information systems to solving the problem of pedestrian accidents by identifying the locations of unsafe bus stops.

B- Methodology:

        We can solve this problem with the used geographic information systems (GIS) based on four basic methodologies:

1.      Geo-coding data from pedestrian accident.

2.      Identifying pedestrian accident concentrations by the map.

3.      Extracting the number of accidence for each bus-stop location in high accident concentration areas.

Ranking the bus-stops with high occurrence accident locations. For example the following table shows a possible accident ranking.  

C-The solutions:

         After identification of the sites of unsafe bus stops, we analyze those locations and identify the causes of the high rate of accidents there. The study of safety features like cross-walks or the lack of thereof, we can identify ways to improve safety at bus-stops. We use several strategies, for example:

1.      Provide signs on the road, near the bus-stop, and along the street encouraging commuters to cross the road using the crosswalk at the nearest intersection.

2.      Provide crosswalks near the bus-stop or construct overpasses near bus-stops

3.      Improve existing locations by paving the road, improving the level of lighting, marking signs for vehicles to reduce speed, and the separation of a pedestrian walk from traffic vehicles.
