Geometric Analysis of Road Segment: Enclosure of inflow and outflow sidelanes

Researchers: Jonathan Wong and GPA Tobias

Abstract

There are a numbers of lanes in a given highway that has a section enclosed by a side lane from one side and an alternative outflow on the other. This section is influenced by the distance or length of the side lane along with its width and the inflow of cars. The distance between the inflows from the right side along the outflow from the left side is considered the section enclosed. The width is considered the number of lanes between the right inflow and left inflow, hence the width of the road. Expected outputs are the outflow from both the main road and the left outflow that is composed of the number of cars dictated by the number of inflow at a specified end time. The simulation then uses these variables to deduce the optimal length of roads with side inflows and outflows. Constants within the system are the speed and the movement of the cars. A portion of the HCM Weaving Methodology will be used in the study but as of this writing, the variables will be limited from speeds of the vehicles. By not factoring in speeds, the difference of constrained and unconstrained weaving speeds will also not be included. A constant speed will be given to the vehicles while tweaking the inflow, width, and formula constants to determine the most optimal length for the weaving section.
