Abstract

The increase in movement between zones between sub-districts in the Regency increases in line with economic development in the region. Parongpon sub-district and Ngamprah sub-district are West Bandung regency areas that have increased economic growth which is quite significant in West Bandung Regency. The geometric redesign research between Parongpong and Ngamprah zones has the aim of adjusting the road geometry based on increasing the volume generation and attraction of traffic movement between these zones. The generation and attraction of traffic movement between these zones is dominated by the volume of vehicles with larger dimensions and heavier loads, so that geometric alignment of the road is required based on the standard slope of the vertical alignment and the super-elevation curve of the horizontal alignment. The research method used is quantitative descriptive in geometric design parameters which are developed in accordance with the development of traffic volume and vehicle types. The research results show the Rise and Attract model of movement between Parongpong-Ngamprah zones with the mathematical model shown by the equation Y = 28.064 +0.0003612X1+0.001X2+0.005X3 with R2 = 0.97. With the influence of the generation of traffic volume movement on these roads, of requires adjustment of the super evaluation curve with a larger radius and smaller vertical alignment slope so that the increase in traffic volume from the influence of the generation and attraction of the movement of the Parongpong-Ngamprah zone can be anticipated with fine.

Abstract

Transyogi road Cibubur is the main road connecting the activity zone in the city of Bogor. This research models the Volume - speed - density relationship model to determine traffic behavior caused by the activity system in that zone. The research methodology used is quantitative descriptive research modeled using mathematical equations. The inter-city traffic movement that occurs on this section causes the traffic flow situation to become unstable, plus the large rate of increase in traffic and the number of vehicles in the area means it is necessary to carry out planning to anticipate future traffic movement needs. A macroscopic approach can show overall traffic flow. This approach is described by 3 parameters, namely traffic flow (volume), density and speed. The Greenshield, Greenberg, and Underwood models can describe the relationship mathematically between these three parameters. The results of the research show that the flow characteristics at peak hour conditions are shown in the Underwood model with the model significance analysis value on Friday having a value of 0.940. For the model equation between Speed and Density we get S = 54.1 Exp (–D/370.15) Volume and Density get V = 54.1 D Exp (–D/370.15) Volume and Speed get V = 370.15 S Ln (54.1/S). The volume - speed - density relationship model shows that traffic in urban areas has characteristics determined by the zones built from the cover area. So, controlling traffic volume during peak hours in this zone must be controlled by adjusting the activity system on the road corridors that are traversed.
