Abstract

The transportation problem causing a traffic jam in this study is a bottleneck of the road, where downstream traffic capacity is smaller than the upstream, usually, happen in the bridge entrance and where the road geometric changes such as four lanes 2 line into two lanes 2 line. This study aims to find a model that represents the mathematical relationship of volume, velocity, and density with manual count method in Jamin Ginting road, km 14.5 with four types of models named Greenshield, Greenberg, Underwood, and Bell and to determine shock wave value. The result of this research is the Greenshield model in the narrowed road which best describes the value of the independent variable (speed) to the dependent variable (density) at the location and the shock wave value at 13.00-13.15 pm (ω = -1.46), 13.15- 13.30-13.45 pm (ω = -1.75), 13.45-14.00 pm (ω = -0.90). The observed maximum queue length is 1.2 km while the most closely approximated result is the Greenshield model with 0.9 km. So the model that best to represent the field conditions is the Greenshield model
