New Project: Performance Evaluation of Detection Technologies for Signalized Intersections in Minnesota

Intersections can be controlled through pretimed systems or vehicle-actuated systems, which detect the presence of a vehicle. Good vehicle detection is the foundation of actuated systems. While loop detectors have been effective workhorses of vehicle detection for MnDOT, changes in vehicle fleets—for example, the use of nonferrous materials—and an increased need to detect vulnerable road users has resulted in an increased use of nonintrusive detection technologies (NIT).

New NIT performance has not been comprehensively tested on Minnesota intersections. For example, few studies have examined the true costs of these new intersection control systems or their appropriateness for given locations.

Objectives

A new research project aims to provide guidance to MnDOT as well as to city and county agencies for selecting the most appropriate intersection control technology for a given location. In addition, researchers will investigate and present information addressing the expertise, effort and material costs required to maintain these systems in Minnesota. The project will produce a decision tool to guide signal design by MnDOT and other Minnesota public works organizations.
