Sustainable Urban Mobility: An Analysis of Street Networks in Phnom Penh

Abstract: A rapid increase in population and demand for private vehicles in Phnom Penh have worsened traffic flow and led to more accidents. Due to unreliable public transport and unsafe road conditions in the city, people prefer driving private vehicles to walking or cycling, leading to daily traffic congestion. What is the best model to resolve this issue? There is no simple or direct answer to this question as traffic conditions anywhere involve many factors. Each factor needs to be considered individually. In this lecture, the author investigates street networks (SNs) – a backbone of the urban transport structures that organize human dynamics and traffic flow in a city. The lecture aims to answer three simple questions: (1) What are the morphological features of SNs in Phnom Penh? (2) Are they vehicular-oriented SNs? and (3) What, if any, are the implications for plans to retrofit SNs to address traffic issues? An analysis of SNs in Phnom Penh will be provided and policy options to retrofit SNs will be discussed.
