Managing Private Vehicles In Asian Cities, Sock-Yong Phang
Research Collection School Of Economics
Asia's rapid urbanization and growing incomes have resulted in a corresponding booming market in motor vehicle sales. In 2013, an estimated 18 million new passenger cars were sold in China. Motor vehicle users generate congestion, pollution, accidents, noise and road damage. Yet, in most cities motor vehicle users often do not pay the full social costs and are therefore implicitly subsidized by non-users. According to the Tom Tom Traffic Index, which is based on GPS data, motorists in the worst congested cities in developed countries spend up to 40% more time for peak hour commutes. This level of delay is …
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang

The fundamental law of highway congestion states that when congested, the travel speed on an expanded expressway reverts to its previous level before the capacity expansion. In this paper, we propose a theory that generalizes this statement and finds that if there exists a coverage effect, that is, the effect of longer road length on traffic conditional on capacity, then the new equilibrium travel speed could be lower than its previous level. Given the fundamental law, the theory predicts that the elasticity of traffic to road capacity is at least 1. We estimate this elasticity for national expressways in Japan …

Road Congestion Pricing In Singapore: 1975-2003, Sock-Yong Phang, Rex S. Toh

Facing traffic congestion in the Central Business District and enormous demands on scarce land resources by the growing number of motor vehicles, Singapore, a small island city-state the size of Seattle, embarked on a bold decision to reduce road congestion by implementing the famous Area Licensing Scheme in 1975. This was a manual system of tolls for multiple entries into the Restricted Zone. While achieving the intended effect of cutting down on the volume of vehicular traffic in the Restricted Zone, the authors (and others) found that the problem of congestion had merely shifted in time and place. Many changes …

This study reviews the efforts of Singapore to curb road congestion through restraints on motor vehicle ownership as well as user fees. In particular, it traces the history of the famous Area Licensing Scheme (ALS), and then discusses its shortcomings, also the need for Electronic Road Pricing (ERP), its advantages and disadvantages and the technology involved in this state of the art system. This paper identifies important research questions to be addressed in connection with the first full-scale adoption of ERP.
