Near crash events are often regarded as an excellent surrogate measure for traffic safety research because they include abrupt changes in vehicle kinematics that can lead to deadly accident scenarios. In this paper, we introduced machine learning and deep algorithms predicting near using LiDAR data at a signalized intersection. To predict occurrence, used essential kinematic variables such late...

INTRODUCTION Traffi c circles have been a part of the U.S. transportation system since the early 1900s. However, traffi c circles faded away from the transportation scenario because of high accident and congestion rates due to the priority given to vehicles entering the intersection. It was not until the adoption of the “modern roundabout” in the United Kingdom during the 1950s that new meaning...

OBJECTIVE To explain a reduction in pedestrian-motor vehicle crashes in Arkhangelsk, Russia, in 2005-2010. STUDY DESIGN Retrospective ecological study. METHODS For 2005-2010, police data on pedestrian-motor vehicle crashes, traffic violations, and total motor vehicles (MVs) were combined with data on changes in national road traffic legislation and municipal road infrastructure. Negative bi...

Intellidrive offers great potential for various new safety and mobility applications. This paper reports on an Intellidrive application for signalized intersection safety, where signals can dynamically adapt to hazardous conditions in order to avoid Red-Light-Running (RLR) related collision. As an important portion of the intersection collision avoidance system, a model for the RLR prediction b...

Abstract This study evaluates the performance and safety effectiveness of mini-roundabouts. Crash, operational, geometric data for 14 mini-roundabouts located in state Michigan were collected both before after installation time periods between 2007 2016. Three years complete crash analyzed utilizing Before-and-After with Comparison Group methodology. A total 28 untreated sites similar character...

Contraflow Left-Turn Lanes (CLLs) have the potential of being a solution for mitigating congestions at signalized intersections where split phasing is recommended or required. However, current signal timing strategy with CLLs cannot be directly applied (SIWSP). To address this problem, study proposed an innovative strategy, which referred to as Counterclockwise Split Phasing (CSP) timing, imple...

In order to reduce the energy consumption caused by frequent braking of vehicles at signalized intersections, an optimized speed trajectory control method is proposed, based on recovery efficiency (BERE) in connection with automated system for vehicle real-time interaction roadside facilities and regional central control. Our objectives were as follows; firstly, establish simulation model hybri...

Intersection is a major source of traffic delays and accidents within modern transportation systems. Compared to signalized intersection management, autonomous management (AIM) coordinates the crossing at an individual vehicle level with additional flexibility. AIM can potentially eliminate stopping in due lights while maintaining safe separation among conflicting movements. In this paper, stat...
