Non-vital advance rail preemption of signalized intersections near highway-rail grade crossings

Description: Technical report examining two strategies were investigated to ensure pedestrian clearance time in intersections near highway-rail grade crossings. The first utilizes a lower-level preemption sequence to guarantee full pedestrian clearance to a terminating phase before the traffic signal starts the preemption sequence. The second strategy uses the pedestrian-omit feature to prevent the controller from activating the pedestrian interval if there is not sufficient time in advance of the start of … more

Network methods for project selection based on optimizing environmental impact

Description: "Traditionally, transportation road networks have been designed for minimal congestion. Unfortunately, such approaches do not guarantee minimal vehicle emissions. Given the negative impacts of vehicle pollutants as well as tighter national air quality standards, it is critical for regions to be able to identify capacity modifications to road networks such that vehicle emission are minimal. This ability combined with land use changes and opportunities for non-auto travel are paramount in helping… more
