Affordable and common modes of transportation in developing cities and their effect on the sustainability of streets

Sustainable transportation - or green transportation - is an important field in terms of generating a healthy environment and upgrading city planning. Street design and modes of transportation are the two main factors that can affect the sustainability of city planning. This paper focuses on designing and planning an efficient, sustainable street using affordable and common modes of transportation, with an emphasis on two cities in Egypt and Lebanon as case studies. Observing developing cities in the field of transportation planning reveals many weaknesses that have a major effect on citizens, such as traffic congestion, a shortage of pedestrian walkways or cycling paths, a lack of affordable public transportation or its sequential movement, and the new modes of informal transportation that have appeared in recent years and have affected the street transportation movement. The aim of this paper is to analyse developing cities in terms of modes of transportation, to discover an effective method of planning city streets. (C) 2017 The Authors. Published by Elsevier B.V.
