摘要

随着孟加拉国等发展中国家工业活动的扩大,近年来机动车辆的购买量也在不断增长。机动车辆数量的增加给工业区的物流运输带来了巨大压力,道路的性能水平也在日益下降。要满足对可靠的交通系统的需求,为道路使用者和物流运作提供良好的兼容性,已经变得相当困难。由于黄麻贸易和工厂加工业的存在,坎奇布尔工业区可被归类为纳拉扬甘杰区的工业中心。多年来,在该地区附近修建了两座大桥,分别名为 Kanchpur 大桥和 Sultana Kamal 大桥,以减轻 N2 国道的压力;然而,情况仍不尽人意,孟加拉国政府(GOB)正在考虑在 Shitalakhya 河上修建第三座大桥。达卡-锡尔赫特公路是 N2 国道系统的一段,连接坎奇布尔工业区和达卡市。这项研究的主要目的是开发一种可用于测量发展中国家公路服务水平(LOS)的方法,并利用它来了解修建第三座希塔拉基亚大桥的必要性。由于道路几何形状、非机动车辆的存在以及交叉口的控制延迟等方面的差异,适用于发达国家的 LOS 测量程序并不适用于发展中国家。通过结合印度昌迪加尔国家技术教师培训与研究学院、美国《公路通行能力手册》(HCM)和孟加拉国道路与公路局(RHD)的标准,制定了一套测量 LOS 的程序。LOS 测量基于四个参数:高峰小时系数 (PHF)、行车速度、负载系数和容积/容量比 (VCR)。数据分析显示,达卡-锡尔赫特公路的 LOS 值在 "E "到 "F "之间变化,而第三座 Shitalakhya 大桥的建设将显著改善道路状况。

Identification of necessity behind the construction of the third Shitalakhya bridge based on level of service (LOS) measurement parameters applicable for developing countries

With the expansion of industrial activities in developing countries like Bangladesh, the purchase of motorized vehicles is also growing in recent days. This increased number of motorized vehicles is creating massive pressure on the logistic movement in industrial areas, and the performance level of roadways is deteriorating day by day. It has become quite difficult to meet the need for a reliable transportation system that can provide good compatibility for road users and logistical operations. Kanchpur Industrial Area can be classified as an industrial hub of Narayanganj District due to the presence of jute trading and plant processing industries. Over the years two bridges have been constructed in the proximity of this area named, the Kanchpur Bridge and Sultana Kamal Bridge to decrease the pressure on N2 National Highway; however, the situation is still not satisfactory and construction of a third bridge over the Shitalakhya River is under consideration by the Government of Bangladesh (GOB). Dhaka-Sylhet Highway is a section of the N2 National Highway system which connects the industrial district Kanchpur with Dhaka City. The main objectives of the study were to develop a methodology which can be used to measure the Level of Service (LOS) of roadways located in developing countries and use it to understand the necessity of the construction of the third Shitalakhya Bridge. LOS measurement procedures suitable for developed countries are not useable for developing countries due to the difference in road geometry, presence of non-motorized vehicles, and control delay at intersections. A procedure has been developed to measure LOS by combining standards of the National Institute of Technical Teachers Training and Research, Chandigarh, India; Highway Capacity Manual (HCM), USA; and Roads and Highway Department (RHD), Bangladesh. LOS measurement was based on four parameters: Peak Hour Factor (PHF), Travel Speed, Load Factor, and Volume/Capacity Ratio (VCR). The data analysis shows that the LOS value of the Dhaka-Sylhet Highway varies within the range from “E" to “F", and construction of the third Shitalakhya Bridge will significantly improve the roadway condition.

期刊介绍: Journal of Urban Management (JUM) is the Official Journal of Zhejiang University and the Chinese Association of Urban Management, an international, peer-reviewed open access journal covering planning, administering, regulating, and governing urban complexity. JUM has its two-fold aims set to integrate the studies across fields in urban planning and management, as well as to provide a more holistic perspective on problem solving. 1) Explore innovative management skills for taming thorny problems that arise with global urbanization 2) Provide a platform to deal with urban affairs whose solutions must be looked at from an interdisciplinary perspective.
