Microsimulation-Based Design of Exclusive Motorcycle Lanes on Urban Arterial Roads

In Indonesia, two-wheeled vehicles, or motorbikes, make up over 80% of all motorized vehicles.These bikes are popular due to their affordability, fuel efficiency, and ability to navigate through traffic quickly.However, the high volume of motorbikes leads to complicated traffic patterns and poses safety risks.To enhance the safety of motorcyclists, lane separation is the most effective engineering solution.This research aims to develop a design model for an exclusive motorcycle lane (EML) on arterial roads in urban areas through microsimulation.The EML design model is created using traffic simulations conducted with PTV VISSIM 2020.The inputs for the simulation are EML width and motorcycle (MC) volume.The EML width ranges from 3.0 meters to 4.0 meters, while the MC volume varies from 910 MC/hr to 4800 MC/hr.The output of the simulation is analyzed to establish the relationship between EML width, motorcycle volume, and the volume-to-capacity ratio (VCR).The modeling will yield the maximum motorcycle volume for each EML width, as well as the relationships between volume, speed, and VCR.According to the EML design model, the maximum MC volume for an EML width of 3.0 m is 3,889 MC/hr, a 3.25 m width, 4,175 MC/hr, a 3.5 m width, 4,565 MC/hr, a 3.75 m width, 5,000 MC/hr, and a 4.0 m width, 5,140 MC/hr.
