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 characteristics in the city, people prefer driving private vehicles to walking or cycling, leading to daily traffic congestion. What is the best model to solve this issue? There is no simple, and direct answer to this question because the traffic condition involves many factors. We need to look at each factor. In this lecture, the author investigates street networks (SNs), which are a backbone of 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) Are there any implications that we could use to retrofit SNs? An analysis of SNs of Phnom Penh and policy adoption to retrofit SNs will also be discussed.
