Traffic and Rural Intersection Monitoring with a Solar-Based Infrared Wireless System. Phase 2 Final Report

摘要

In this study we analyze the effectiveness of an experimental Dynamic Speed Monitoring (DSM) system that was installed in the summer of 2007 at the southbound entry loop ramp at the US 27/US 192 trumpet interchange in Polk County, Florida. The analysis aimed at assessing the effect of installing the DSM system, both on the long and short terms, on vehicles' approach speed, at a point 250 feet in advance of the southbound entry ramp curve (also the detection zone of the DSM system radar). Vehicular speeds were recorded at different time intervals, including before and after the DSM installation.
