Project Details: NMDOT CV Speed Harmonization

PROJECT OVERVIEW

Project Name:

Project Details: NMDOT CV Speed Harmonization

Description:

The Connected Vehicle Speed Harmonization application determines speed recommendations based on traffic conditions and weather information. The speed recommendations can be regulatory (e.g. variable speed limits) or advisory. The purpose of speed harmonization is to change traffic speed on links that approach areas of traffic congestion, bottlenecks, incidents, special events, and other conditions that affect flow.
