Abstract

The high number of accidents on Jl. Sudirman Metro city in Lampung is caused by presence of mix traffic, as well as the absence of special treatment for vulnerable motorcycle users, resulting in conflict between motorbikes and other vehicles that have the potential to cause accident. This analysis was carried out to reduce the frequency of high accidents and fatalities due to accident on Jl. Sudirman, an analysis of motorbike lane requirements on Jl. Sudirman and speed management was conducted, one of which was speed limit determination. The analysis samples taken by 7 days survey from 6.00 am – 06.00 pm on Jl Sudirman Metro city Lampung. The result of the surveys showed the criteria for motorcycle lane determination criteria not suitable to implement on Jl. Sudirman segment if it is in accordance with specified indicator because the motorcycle traffic volume is less than 674 smp/hour and 2696 vehicle/hour. This paper indicates that survey analysis on motorcycle driver discipline by using of left flow at Jl. Sudirman Metro city Lampung was not significant. In order to reduce the frequency of high accident we need speed limiting guards with maximum speed 40 km/hours and the signs for motorcycle instruction using the left lane.
