Study of potential implementations for motorcycle lanes in Padang city

Currently, two-wheeled vehicles or motorcycle dominate more than 80% of motorized vehicles in Indonesia. In addition to low prices, these motorized vehicles are fuel efficient, have easier and faster mobilization. However, the large number of motorcycles results in complicated traffic operations and reduced levels of safety. Lanes separation is the best engineering solution to overcome this problem. The purpose of this study was to review the potential application of motorcycle lanes in the city of Padang, a case study on the Raya Ampang and By Pass roads. Collecting the primary data were conducted by Video Image Processor. Each road was carried out recording for 1 day during peak hours in the morning, afternoon, and evening. Analysis of road performance is based on the Highway Capacity Manual of Indonesia (MKJI) 1997 with the degree of saturation (DS) parameter. Road performance analysis is reviewed by comparing the existing conditions and the conditions in which the inclusive motorcycle lanes are applied. The results of the study show that both the Raya Ampang and By Pass streets is feasible to provide an inclusive lane or shared lanes for motorcycles-with a lane width of 3 meters. With motorcycle lane application scenarios, on the Raya Ampang street for non-motorcycles lanes, there is a 10.7% increase in road performance, while for By Pass road, the increase in road performance is 31.5%.
