Safe-D: Safety through Disruption

Developing an Intelligent Transportation Management Center (ITMC) with a Safety Evaluation Focus for Smart Cities

Abstract

Transportation safety planning challenges in the era of smart cities entail understanding safety impacts from disruptive technologies, measuring the effectiveness of safety countermeasures, proactively identifying high crash risk locations, etc. Recent advancement in communication technologies and big data analytics enables us to deal with these challenges in a computationally efficient way. Traditional transportation management centers (TMCs) have limited capability to utilize large amounts of data to properly evaluate transportation safety. The goal of this project is to develop an intelligent transportation management center (ITMC) that adopts automated video data analysis to evaluate safety. The proposed ITMC demonstrates how intelligent transportation systems (ITS) technologies and big data analytics can be utilized to proactively assess transportation safety at signalized intersections. Conventional methods of traffic safety risk assessment at signalized intersections, measured by number of roadway crashes per unit of exposure, would require a long observation time as crashes are rare events. The proposed ITMC adopts safety surrogate measures (SSMs) to identify near crash situations that can be applied in proactive risk calculations.
