Deficiencies of existing public transport system and a proposal for integrated hierarchical transport network as an improvement options: a case of Dhaka city

Abstract

Public transport plays an important role in providing easy and affordable accessibility and mobility for dwellers in a city. This demand for transportation is brought about by the increased population of connecting nodes, cities, the rural-urban migration, and the scope for socio-economical facilities i.e. better opportunities for jobs, health facilities and educational scope etc. thus the economic viability of the people which leads to an increase in the usage of private vehicles. Dhaka is an over densely populated city and its transport system comprised of many different modes of travel – both motorized and non-motorized using the same road space – resulting in a high level of operational disorder, that significantly diminishes the efficiency and effectiveness of the existing transport uses. Dhaka is experiencing lots of traffic congestion and a great lack of traffic management. There has been no study dedicated to overcome the situation. Therefore, there is an urgent need to introduce a well-organized, properly scheduled rapid mass transit system minimizing the existing deficiencies. In this paper, an attempt has been made to identify the deficiencies of existing public transport system to put forward for an appropriate rapid mass transit system to recover the huge demand. An overview of the existing modes of travel and operation characteristics has been described. Finally, some proposals for integrated hierarchical transport network options are highlighted with the context of prevailing land use and transport characteristics, socio-economic context of Dhaka Metropolitan city. The findings of this research help planners and decision makers to optimize the investment in transport infrastructure.
