Abstract

In populated cities with high traffic congestion, traffic information may play a key role in choosing the fastest route between origins and destinations, thus saving travel time. Several research studies investigated the effect of traffic information on travel time. However, little attention has been given to the effect of traffic information on travel time according to trip distance. This paper aims to investigate the relation between real-time traffic information dissemination and travel time reduction for medium-distance trips. To examine this relation, a methodology is applied to compare travel times of two types of vehicle, with and without traffic information, travelling between an origin and a destination employing probe vehicles. A real case study in the metropolitan city of Tehran, the capital of Iran, is applied to test the methodology. There is no significant statistical evidence to prove that traffic information would have a significant impact on travel time reduction in a medium-distance trip according to the case study.

Dr.Golroo has been an assistant professor at the Amirkabir University of Technology, Civil and Environmental Engineering Department since January 2012. He is a director of Artificial Intelligence and Image Processing lab and Amirkabir Sustainable Transportation Infrastructure system. His field of expertise is automated data collection from transportation infrastructures such as pavement, rails, etc. He is also a Director of Scientific and international Cooperation of Amirkabir University of Technology.

Mahdieh Hasani, M.Sc. student of Transportation Engineering, San Diego State University, San Diego, CA, USA

I am a civil engineer in the field of Transportation Engineering from San Diego, California. I am currently working as a graduate research assistant at San Diego State University Smart Transportation Analytics Research lab. I am originally from Tehran, Iran. I received my Bachelor’s degree in Civil Engineering from Amirkabir University of Technology in 2016. My passion for learning and education encouraged me to travel to the United Sates to pursue Master's degree in Transportation Engineering at San Diego State University. My research work is mainly focused on drivers', pedestrians’, and bicyclists’ safety. I also have experience in big data management and statistical analysis.
