GIS-based analysis accessibility to destinations based on public transport

Abstract EN

Baghdad city depended on the private auto in transport and this led to great problems with increasing congestion and traffic problems.

Existing public transport suffers from poor accessibility to opportunities which is considered the main existing problem.

The local agency decided to construct Baghdad Elevated Train as one of the keys to solve this problem and decrease congestion.

This study aims to discuss the changes that the installing of the planned train line could make, by using the Geographical Information System (GIS) to model the transportation networks (sidewalks, public transport network, and the planned elevated train) for two scenarios, first for the current public transport network and second for the long-term situation of the adding of the planned train, furthermore, to find the coverage area for each station and determine the population can be served for each station depending on the census of the zones for the year 2020.

The modeled network databases were used to create the closest facility between the centroid of the 43 zones and the selected facilities (Commercial, Educational, Governmental, and Hospitals).

The results revealed that the additional service of the train reduced the travel time between Al-Sadr City to four destinations selected for the mentioned facilities by the following percentages (62% , 40% , 46% , and 65% ) respectively.

Moreover, the population coverage stated that stations 8, 9, and 10 are the most Baghdad city depended on the private auto in transport and this led to great problems with increasing congestion and traffic problems.
