Introduction: This study aims to understand the trip characteristics of private and public transport users in Kuala Lumpur, and the intention of private motor vehicle users to shift to rail transport if available. Method: We conducted a travel survey in the corridor of an upcoming mass rapid transit line in Kuala Lumpur. We then analyse the characteristics of the trips recorded from the survey on a weekday and weekend. We used binary logistic regression to find the association between the trip characteristics and the intention to shift from private motor vehicles to rail transport if available. Results: There were less than 15% of public transport users among the survey respondents. However, 48% of the weekday trips and 39% of the weekend trips were intended to shift to rail transport if available. Regression for the weekday trips showed that trip duration, distance, purpose, vehicle occupancy, and presence of child passengers were significantly associated with the intention to shift. For weekend trips, only the trip duration and presence of child passengers were significantly associated with the intention to shift. Conclusion: This study shows that the population's intention to shift from private motor vehicle to rail transport could be influenced by the trip characteristics. Kiggundu, 2007). Consequently, forests were cleared to build more roads to accommodate the large volume of vehicle traffic. Such situation clearly connotes the need for an urgent improvement of transport system in the city. Public transport is an important element in the global propagation towards sustainable transport. Compared to the neighboring Asian countries, Malaysia has a relatively low rate of public transport usage (Almselati, Rahmat, & Jaafar, 2011). The modal share of public transport had reduced considerably from 34% in 1985-10% in 2008 (Performance management delivery unit (PEMANDU), 2010). Based on Jemali (2011), 83% or 6 million trips in the Kuala Lumpur metropolitan area were made on private motor vehicles, while only 17% or 1.24 million trips were made by public transport. This was partly due to the insufficient public transport network, where only 10% to 20% of the urban areas were accessible by rail transit (Ministry of Natural Resources and Environment Malaysia (NRE), 2011). Nonetheless, rail transport constituted 52% of the public transport modal share (Land Public Transport Commission (SPAD), 2014). Therefore, the government has put in concerted efforts under the Land Public Transport Master Plan to improve the public transport infrastructure in Kuala Lumpur (Land Public Transport Commission (SPAD), 2013).
