Traffic Pattern Analysis from GPS Data: A Case Study of Dhaka City

Abstract

Traffic congestion is one of the most alarming problems of Dhaka, the capital of Bangladesh. However, not much work had been done on traffic pattern modeling for Dhaka city. In this paper, we analyze traffic intensity pattern computed from GPS data. The data contains traffic intensity information for 11,769 road segments over 15 days. We analyze the impact of marketplaces, number of road intersections, and having rickshaw free roads on the traffic intensity. In order to analyze the traffic pattern at a macroscopic level, we analyze the traffic pattern of the 13 zones of the city proposed by RAJUK, the authority responsible for the development of Dhaka. For each zone we investigate the impact of a number of different factors, e.g., land use, number of bus routes, number of road intersections, on the traffic intensity.
