Investigating the Occupants' Behaviors and Perceptions Concerning the Sustainable Transportation System in Tehran City

Abstract

A transport crisis of major proportions is looming on the horizon in many of the world's cities. Road travel speeds during peak hours have already fallen below that of horse-drawn carriages, popular 80 years ago. Increasing motorization and air pollution threaten economic development as well as the environment. However, opportunities exist to solve these problems by limiting the demand for transport without affecting socio- economic development. An efficient and equitable urban transport policy can achieve its objectives by using a combination of new investment, economic incentives as well as adequate planning and regulatory measures. This will reduce overall travel and ensure the travel that occurs is safe, efficient and environmentally sustainable, as it will be discussed in this article. This paper investigates how sustainable transportation concerns systems, policies, and technologies and also its aims for the efficient transit of goods and services, and sustainable freight and delivery systems. The results show that there are important key issues in sustainable transportation such as Access not mobility; Moving people not cars; Reclaim city space for walking and pedaled vehicles and Stop subsidizing private motor vehicle. Besides the design of vehicle-free city planning, along with pedestrian and bicycle friendly design of neighborhoods is a critical aspect for grassroots activities.
