Developing a Quality of Signal Timing Performance Measure Methodology for Arterial Operations (NDOT 607-17-803)

The Moving Ahead for Progress in the 21st Century (MAP-21) Act and the Fixing America's Surface Transportation (FAST) Act have emphasized performance-oriented and outcome-based transportation planning. While various performance measures for freeway operations have been established, methodologies for establishing arterial performance measures have not been defined. Conventional approaches to arterial performance measurement include the analytical methods documented in the Highway Capacity Manual (HCM). These methods describe arterial performance incorporating traffic delay and stops; the methods can be used to determine the quality of signal timing on an arterial road, making it a cost-effective engineering solution. In Nevada’s urban areas, signalized arterials carry nearly 40% of the total vehicle miles of travel (VMT); as a result, these arterials play a critical role in the overall transportation system’s efficiency. It is imperative that performance measurement criteria are established, so that the quality of signal timing and coordination along major arterials can be assessed. Efficient arterial operations and desirable performance outcomes cannot be achieved without traffic signals operating at their optimal levels. This research project, conducted on behalf of the Nevada Department of Transportation (NDOT), seeks to develop a scoring methodology for assessing the quality of signal timing along signalized arterials. It is anticipated that this scoring methodology will yield an index score based on common performance measures, that are obtained through either probe vehicle travel runs, or signal controller sensor and timing data.
