Travel time reliability is an important metric of traffic signal system operations and an important consideration of the user experience. A number of different methods have traditionally been employed to track the time a vehicle takes to pass through a corridor. This study compares several different measures to track travel time through the Lincolnway corridor in Valparaiso Indiana, including Bluetooth MAC address collection, GPS logging application, commercial traffic study software, and pilot car techniques. The travel time on Lincolnway is of special interest this year due to the City of Valparaiso's recently completed traffic signal retiming project. Travel time information collected as part of this research was compared to data collected before the retiming project. The effectiveness of various travel time data collection techniques is presented as well as an evaluation of the change in travel time due to the retiming project.

Biographical Information about Author(s)

Lauren Zeeb is a junior civil engineering major who is interested in the transportation profession. Lauren contacted Professor Jay Grossman about a possibility to do research with him. Professor Grossman suggested travel time reliability as that was something he had experience with and would be a good first research project and she was very interested in the topic.
