Service Frequency and Service Hours Evaluation for Bus Service in West Klang Valley

The Malaysian government has taken an initiative to mitigate public transport issues in the Klang Valley through the Land Public Transport Commission (SPAD). Several issues were raised by passengers in Klang Valley in regard to public transport, such as long waiting time and poor management of bus service hours. This study is aimed to investigate the service frequency for bus service performance and the public bus service hours in Klang Valley. Five different areas were selected, which consisted of three routes for each area in west Klang Valley, which were Klang, Shah Alam, Subang Jaya, Petaling Jaya, and Puchong. The time interval for every scheduled bus departure, average time interval, and bus service hours were determined based on the collected data. The result showed that Puchong has the shortest average time interval for service quality. Therefore, the bus performance with regard to service frequency and service hours should be improved to provide the public with better service.
