Ergonomics in Traffic Control and Surveillance System for Expressway: Malaysia Experience

Abstract

There are close to a dozen toll expressway in Malaysia built by the private sectors and a few more in the list waiting to be constructed. The purpose is basically to provide a better alternative to the one provided by the government in terms of smooth traffic flow, less congestion and accident and at the same time to help spur the economic activities that connecting major cities through out the nation. Surprisingly only three expressway operators thus far that have put the traffic control and surveillance systems (TCSS) in place. TCSS is basically a supporting system to aid the expressway operators in running and operating the expressway as well as in providing assistance to the users a smooth and comfortable journey. Following to the above matter an ergonomics study is carried out to confirm the specification on design aspects. The studies will include the rest and service area (RSA), emergency telephone (ET) system and variable message sign (VMS). Basically the design at present is based on anthropometrics data based on Malaysian population.
