Abstract

The increase in the number of vehicles is not in line with the increase in transportation infrastructure. The construction of flyovers is one of the measures to provide transportation infrastructure that helps to enhance thehighway capacity. However, there are several things that need to be considered of the construction of flyover. In addition to reducing traffic density, it is also necessary to pay attention to the new routes that will be chosen to be the solution to the existing traffic congestion. The research objective is to analyze the performance of the section of Jl. Indra Bangsawan in its existing condition and provides alternative solutions so that  it is more optimal. 1997 Indonesian Road Capacity is used to analyze the performance of this intersection.Based on the results of research, it is known that the existing conditions of each segment are saturated (DS> 0.70), namely in the first segment of 1.16, Segment II of 1.37 and Segment III of 1.24, with the highest density in segment II. To improve the performance of the section, several alternative improvements were made with widening road dimensions, applying one-way systems, closing lanes and controlling side barriers. From these alternatives an effective repair solution is the application of a one-way system and control of side barriers.Keywords: Degree of Saturation, Capacity, Density, Roads

Abstract

Traffic accidents are serious problem in Bandar Lampung City, especially the Soekarno-Hatta Bandar Lampung By Pass Road, considering that this road is the primary arterial road that should not be disturbed by shuttle traffic, local traffic, and local activities. Roadside activities are one of the disruptions that can cause accidents and need to be analyzed. Blackspot are determined by the Equivalent Accident Number (EAN) method based on accident fatality rate each segment of the road. Roadside activities are grouped into pedestrians and crossers (PED), park and stop vehicles on the side of the road (PSV), slow moving vehicles (SMV), also enter and exit vehicles of activity centers (EEV). Analysis with linear regression is used to calculate the level of impact of roadside activities with accident rates. From 25 segments along Soekarno-Hatta Road, 16 segments are classified as blackspot and 6 segments are still classified as blackspot until 2017. EEV is the highest number that affects the decrease in the number of accidents, PSV for the 2nd number, SV for the 3rd number and PED for the smallest number. Besides the average vehicle speed is only 42,8 km/h due to the high volume of vehicles with an average of 2708 skr/h also the damaged of some segments and poor support facilities of the road.

Abstract

The behavior of drivers who do not consider the movements of other drivers can cause traffic problems, such as congestion and traffic accidents that can occur on the road. The stagger intersection at Jalan Raden Ajeng Kartini is often crowded with vehicles that can cause congestion. This is due to the behavior of drivers crossing from Cut Nyak Dien road to Lindu road, causing a conflict of delays influenced by weaving movements. The purpose of this research is to analyze the amount of delay due to weaving motion on the Raden Ajeng Kartini road.This study uses an analysis of the gap acceptance approach, to get the big results of vehicle delays caused by weaving motion, the average gap time and critical gap.The results of this study show that the vehicle delay caused by weaving motion is 3.20 seconds and 8.93 seconds in the morning and evening. The average gap time was 82.50 seconds in the morning and 94.36 seconds in the afternoon, while the critical gap was 4.34 seconds in the morning and 3.88 seconds in the afternoon. Keywords: Gap Acceptance, Weaving, Delay.
