Implementation aspects of circular mass rapid transit system in dense urban setting of metro Dhaka

Abstract

This research paper has been prepared aiming to propose a rail based mass rapid transit (MRT) system to be implemented along a circular loop passing through high density residential and developing areas of Dhaka city. A study has been carried out to highlight priority implementation of a rail based circular mass transit line in Dhaka city after MRT line-6, which is now in progress. As per transport development plan for Dhaka city, the proposed circular line (MRT Line-5) in STP has been suggested for implement as 2 (two) East-West lines in recently Revised Strategic Transport Plan (RSTP) in order to provide more command area in future developing Eastern fringe area. However in this thesis study for Master of Science in Engineering, an option has been proposed to implement the circular MRT along a corrected and modified from original STP alignment as shown in study in order to get rid of some unavoidable conflicts and hindrances during construction. Bangladesh Government has already taken initiatives to implement MRT line-I and MRT line-5 (RSTP) in cooperation with JICA and a memorandum of understanding (MOD) has already been signed between GOB and JICA. Under this changed scenario, the alignment of this proposed circular MRT line 05 in this thesis study is again changed & modified as a semicircular loop. It is envisaged that the north segment of the semicircular loop will be continued up to Vatara with a future provision of link with Vulta. Similarly the south segment of the same will be extended from Rampura to Bonossree with future link to Meradia. This modification in this research study will enable another mass transit line MRT 01 as recommended in RSTP will be constructed underground along Pragoti Sarani (Natunbazar- Rampura) without any conflicts. Considering funding restriction and construction preference a strong recommendation has been given in this study to implement the Circular Mass transit line (MRT Line-5) modified as a semicircular loop on highest priority basis to keep people moving instead of keeping arrested in congestion. In this research study, a better alignment has been proposed for MRT Line;.5.For the sake of avoiding conflicts and inaccessibility, the total line was proposed partly elevated & partly underground. Also Depot location has been proposed with a vision of being usable in future for other MRT line-2 also as proposed in Revised Strategic Transport Plan (RSTP). 11
