STUDY ON HISTORICAL COMMUTER TRAFFIC PATTERN OF DHAKA-CHITTAGONG HIGHWAY (NH-1) OF BANGLADESH

Dhaka-Chittagong Highway, which is the main transportation artery for the economy of Bangladesh. Approximately 257 kilometers in length, the road links the country's two largest cities, Dhaka and Chittagong. The NH-1 is a top development priority and is the most demanding road in Bangladesh. Recent enormous congestion, long traffic queue and road accidents ascertains that the highway was built based on non-engineered way or else proper traffic study was not performed during the construction of that highways. Regrettably no extensive traffic studies have been completed on NH-1 by the Government of Bangladesh till now. However, an attempt is made through this research to establish daily, weekly and monthly traffic flow factors along NH-1. Usually traffic data collection and analysis follows varying trends and plays an important role in the evaluation and management of road network schemes. Traffic flow pattern is highly required for different purposes by different ministries and organizations in Bangladesh.
