A Study on the Influences of Exclusive Stopping Space on Saturation Flow (Case Study: Bandar Lampung)

Abstract

The existence of exclusive stopping space (ESS) at the signalized intersection is expected to improve the performance of intersection, by collecting the motorcycle in an exclusive space and discharging it early when the signal is display green. This research compares the level of saturation flow on the approach with ESS and approach without ESS and finds that ESS's effectiveness is influenced primarily by occupancy rate. The findings of this study indicated that at 71% of ESS occupancy rate, the approach was able to discharge the saturation flow by 20% higher than the approach with a width of 4.5 m but without ESS. On the contrary, the approach without ESS with a width of 6.5 m looks better in discharge saturation flow compared with the approach with ESS but with an occupancy rate of only 38%. Careful design is highly recommended especially the area of ESS provided for motorcycle so that the functions performed by exclusive space run an effective way as planned.
