Benefits of Advanced Traffic Management Solutions: Before and After Crash Analysis for Deployment of a Variable Advisory Speed Limit System
<p>Variable speed limit (VSL) systems are important active traffic management tools that are being deployed across the U.S. and indeed around the world for relieving congestion and improving safety. Oregon’s first variable advisory speed limit signs were activated along Oregon Highway 217 in the …

Development of a Tool to Calculate Appropriate Advisory Speeds on Horizontal Curves
… attentive while driving. To address this issue, advisory speeds are posted on horizontal curves to warn drivers to slow down for their safety. There are six main procedures to assign advisory speeds. This paper focuses on two of these methods, finds a connection between the two, and develops an …

Development and Demonstration of a In-Vehicle Lane Departure and Advanced Curve Speed Warning System
… information which includes road curvature, speed-limit, position. etc. of a given curve. In this report, a lane detection method is proposed which uses a standard GPS receiver to determines the lateral shift of a vehicle by comparing a vehicle’s trajectory to the reference road direction …

Multidimensional Warnings: Determining an Appropriate Stimulus for a Curve-Warning Device
… exist, from late notification of direction and speed, varying methods for determining advisory speeds, as well as driver unfamiliarity and/or over confidence. A curve-warning device, a device that notifies the driver of an upcoming curve and, possibly, conveys its vehicle-specific advisory speed …

Eco-Cooperative Adaptive Cruise Control at Signalized Intersections Considering Vehicle Queues
… that was developed in an earlier study provides advisory speed recommendations to drivers to reduce vehicle fuel consumption levels in the vicinity of traffic signalized intersections. The research presented in this thesis enhances the algorithm by adding a queue length estimation component and …

Multidimensional Warnings: Evaluating Curve Warning Stimuli in an On-Road Environment
… as driver acclimation to inconsistency in posted advisory speeds. In-vehicle curve warning devices (CWDs) may be an effective alternative for reducing the number of collisions at curves. Multi-modality displays have elicited positive driver results and should be further explored. The objective of …
