Study of Pedestrians Proportion to Roadside Friction Index

Abstract

Activities of land use on the roadside have an impact on traffic. The more roadside activities increasingly affect the performance of the road section. This research was conducted on 2/2 UD type of road and the purpose of the study was to determine the effect of the proportion of roadside friction (pedestrians) to traffic characteristics and roadside friction index on access roads of Makassar Municipality and Gowa Regency. Greenshields model is used to determine the relationship between speed-flow-density. The results showed pedestrians are very influential in the average speed of space and free-flow speed. The greater the proportion of pedestrians as roadside friction, the value of the roadside friction index increases, but the value of the average speed of space and free flow speed decreases. Motorized vehicles will run slower to avoid or adjust to the pedestrian speed, especially light vehicles and heavy vehicles, yet the addition of the pedestrian does not significantly affect the movement of motorcycles.
