This research is a preliminary ealuation of the effectiveness of the High Occupancy Vehicle (HOV) lane along I-40 eastbound Memphis, TN. This HOVlane is operated from 4 p.m. to 6 p.m. during weekdays. Data for the analysis was collected over a two month period in June and July 2011 using standard techniques as well as low cost smart phone apps and consumer grade GPS navigation products. The data collected included hourly volume data, average vehicle occupancy, violation rates, travel times and carbon emissions estimates. The analysis consisted of three methods of measuring effectiveness: increasing person throughput, providing travel time benefits and environmental benefits. To check for statistically significant differences between HOV lane and other GP lanes statistical methods including the two sample t-test and Mann Whitney test were used. a concept of a beffer index was also used to check the travel time reliability for each lane. The result showed that the objective of increasing person throughput is not met for this corridor within Memphis, TN, and recommendations to improve the effectiveness of the HOV lane are presented.
