Transit Oriented Development (TOD) - A Road towards Sustainable Transportation in Dhaka Nuzhat Azra Lecturer, Department of Civil Engineering Ahsanullah University of Science and Techology Dhaka, Bangladesh Abstract—Planners and urban designers across the globe are promoting transit oriented development (TOD) to encourage sustainable development. TODs are compact, mixed-use developments that facilitate walking, bicycling, and use of public transport through its urban design. In an overpopulated city like Dhaka, uncontrolled urbanization is the major cause of congestion, road accidents, environmental pollution and various other traffic related problems. Hence sustainable transportation is the only option…show more content…
Smart growth calls for building communities that are more hospitable, productive, and fiscally and environmentally responsible than most of the communities that have been developed in the last century. Transit Oriented Development (TOD) has recently become a popular tool to promote smart growth and sustainable development. TODs have been hailed as a model for integrating land use with transportation in the interest of smart growth (Calthorpe, 1993; Cervero, 1998; Newman and Kenworthy, 1999; Renne and Newman, 2002; Renne and Wells,…show more content…
THE CONTEXT OF SUSTAINABLE TRANSPORTATION A detailed exposition on the concepts, principles and strategies of sustainable transport has been provided by Replogle (1990). The emerging sustainable transportation paradigm seeks to maximize efficiency in overall resource utilization. This is achieved by increasing modal diversity, paying more attention to the pattern of transportation and land use and encouraging use of efficient transportation modes whenever practical, often by encouraging better connectivity between modes. Replogle (1990) argued that efficient and sustainable strategies strive for a modally balanced system, augmenting traditional transportation with larger volume, longer distance, and faster speed movements and promoting infrastructure and land use patterns that maximize opportunities for pedestrian, cycle and cart traffic to meet short distance movements, including access to higher speed, larger capacity motorized or rail transport system. Efficient and sustainable transport strategies promote the mechanization of goods and person movements made by low income people replacing the sheer drudgery of unaided human-powered transport with greater use of bicycles, carts, rickshaws, and other non-polluting, non-resource intensive low cost tools for transport. The principles of sustainable transport also encourage utilization
