OBJECTIVES In urban settings, pedestrian fatalities and injuries are concentrated on major roads. This study aims to describe urban intersections with major roads (arterials and collector roads) and explore the association between intersection characteristics and injured pedestrians. METHODS From a stratified random sampling in Montréal, Quebec, 512 intersections were selected and their chara...

Traffic Management and Information Systems, which rely on a system of sensors, aim to describe in real-time traffic in urban areas using a set of parameters and estimating them. Though the state of the art focuses on data analysis, little is done in the sense of prediction. In this paper, we describe a machine learning system for traffic flow management and control for a prediction of traffic f...

The continuous green T intersection is characterized by a channelized left-turn movement from the minor street approach onto the major street, along with a continuous through movement on the major street. The continuous flow through movement is not controlled by the three-phase traffic signal that is used to separate all other movements at the intersection. Rather, the continuous through moveme...

Signal cycle failure (or overflow) is an interrupted traffic condition in which a number of queued vehicles are unable to depart due to insufficient capacity during a signal cycle. Cycle failure detection is essential for identifying signal control problems at intersections. However, typical traffic sensors do not have the capability of capturing cycle failures. In this paper, we introduce an a...

arterial corridor greatly impacted by strip commercial development. The data-gathering efforts consisted of extensive traffic counts and travel-time and delay studies. This enabled us to see firsthand the great congestion that was occurring on the street. At the four most-congested intersections, unequal queuing between the two through traffic lanes was observed. In all cases, the right lane’s ...
