Pedestrian safety under permissive left-turn signal control

An Application for Driving Simulator Technology: An Evaluation of Traffic Signal Displays for Protected-Permissive Left-Turn Control

Guidelines for Multicriterion Decision-Based Left-Turn Signal Control

left-turn lanes; that is, protected left-turn control is recommended if the number of left-turn lanes exceeds 1. Such a decision process lacks a balanced consideration of other factors such as opposing traffic volume, which may be very low; therefore, the decision may not be rational at all locations or under all conditions. In many cases, an alternative left-turn control type might provide equ...

State-of-the-art Literature Review on Permissive/ Protected Left-turn Control

In spring 2010, the Illinois Department of Transportation initiated an areawide implementation to integrate the flashing yellow arrow as the display for the left-turn permissive interval at more than 100 intersections operating with protected/permissive left-turn (PPLT) control. Bradley University was retained to perform an effectiveness evaluation of the FYA at these locations. The purpose of ...

Deciding Alternative Left Turn Signal Phases Using Expert Sytiems

T Texas Transportation Institute (lTI) conducted a study to investigate the feasibility of applying artificial intelligence (AI) technology and expert systems (ES) design concepts to a traffic engineering problem. Prototype systems were developed to analyze user input, evaluate various reasoning, and suggest suitable left turn phase treatment. These systems were developed using AI programming t...

Exposure to lateral collision in signalized intersections with protected left turn under different traffic control strategies.

This paper proposes an original definition of the exposure to lateral collision in signalized intersections and discusses the results of a real world experiment. This exposure is defined as the duration of situations where the stream that is given the right-of-way goes through the conflict zone while road users are waiting in the cross-traffic approach. This measure, obtained from video sensors...
