Travel Time Performance Measures for Passenger Cars and Trucks by Road Facility Type
Publication: International Conference on Transportation and Development 2021
ABSTRACT
Freight transportation is a growing industry in both developed and developing countries. Products ranging from groceries to medical supplies require quick and reliable shipping. In this era of e-commerce, consumers expect reliable shipping service standards. Further, quicker shipping options are considered a requirement rather than an option for the freight companies responsible for first- and last-mile deliveries. The increasing demand for freight transportation and better shipping standards is leading to high truck traffic on roads. Transportation planners, engineers, designers, and freight operators have been making significant efforts to improve the reliability of truck transportation services. Travel time reliability measures are an effective way for planners to gain an understanding of traffic stream performance that will help them make informed decisions. These measures are developed using passenger car or mixed traffic stream data, making their applicability to trucks (exclusively) questionable. This research focuses on gaining an understanding of whether travel time reliability measures of trucks and passenger cars significantly differ from each other. Travel time data for roads in Mecklenburg County, Wake County, and Buncombe County in North Carolina were considered for analysis. Descriptive statistics were computed, and statistical analysis was conducted to examine the distinctive nature of their behavior. Differences in values and significance of performance measures were observed by facility type, time-of-the-day, and day-of-the-week.
