Abstract
The main focus of this study is aimed at understanding the factors causing traffic congestion in Colombo Metropolitan Area. Therefore, the study was carried out to address major research questions as, what factors affecting the current vehicle traffic flow, followed by what are the impacts of traffic congestion and what is the opportunity cost of time and fuel wastage cost of congestion. The main objective of the research was to identify the factors affecting the current vehicle traffic flow in Colombo, while the specific objectives of the research are to identify the impacts of traffic congestion, to estimate the opportunity cost of time and fuel wastage cost and to identify whether the commuters are satisfied with the strategies implemented by the government to mitigate traffic congestion. Accordingly, from the survey conducted for the commuters, the researcher identified factors such as “Growth of population and vehicles”, “Unforeseen circumstances”, “Events and incidents” has an individual effect on the current vehicle traffic flow. In addition to that the researcher identified the main impacts of traffic congestion as “Time”, “Fuel”, “Earnings” and “Productivity”. And also the esearcher identified that majority of the commuters are satisfied with the Bus Priority Lane and Park and Ride, while majority of the commuters neither satisfied nor dissatisfied with the Ferry Service as a strategy implemented to mitigate traffic congestion.
Highlights
Traffic congestion remains a significant problem in most cities around the world, especially in developing countries, resulting in huge delays, increased fuel wastage and monetary losses
The association between the current vehicle traffic flow and the identified four factors are tested by using the Pearson Correlation Analysis
The hypothesis used in Correlation Analysis is as follows; H0: There is no association between current vehicle traffic flow and ith factor
Summary
Traffic congestion remains a significant problem in most cities around the world, especially in developing countries, resulting in huge delays, increased fuel wastage and monetary losses. Due to inadequately planned road networks, the common outcome in several developing countries is the existence of small critical areas which are common hotspots for congestion. Inadequate traffic management around such hotspots is likely to result in extended traffic congestion. Traffic congestion is much more a result of the basic mobility problem, which is that several people want to move at the same time every day. The efficient functioning of the whole society system requires people to go to work, go to school, and even walk around at the same time and interact with each other.
