The tool presented here estimate the capacity utilization of an intersection using a critical movement analysis. Protected and permitted configurations are included in the analysis. In addition, HCM and Webster method of calculating a cycle length given the startup loss time, peak hour factor, yellow time and critical v/c ratio are provided.

A tool created below allows to conduct traffic operations analysis for three highway facilities: Basic freeway segment (Operations and Planning), multi-lane, and two-lane highway (Bicycle). The analysis of these facilities were implemented following the procedure recommended in the Higway Capacity Manual (HCM - 2016). Other type of facilities, such as merge, weaving, roundabout, traffic signal, etc. are under development. In addition, I will be extending these applications to have an automated report generation (.pdf) to summarize the result of analysis. Use a link below under "LEARN MORE" to test the app.

This tool analyzes the signal warrant 1. The Warrant 1, Eight-hour vehicular volume, is one of the 9 warrants that estimates whether there is a need for traffic signal to be installed at an intersection for the purpose of improving traffic safety and operations. These guidelines are provided by the Manual on Uniform Traffic Control Devices (MUTCD). According to MUTCD, the warrants are threshold conditions based on the average conditions that help in the process of making decision regarding installing traffic control devices.
