Abstract

Value of time was estimated for commercial vehicle operators in Minnesota to quantify the effects of spring load restrictions. A sample was constructed from several trucking industry sources to conduct a survey. Interviews were conducted using an adaptive stated preference (ASP) survey to derive an estimate to the nearest dollar. A tobit model was fi t to the data from the interviews to derive the estimate for value of time, $49.42 per hour. Variation in the distribution of values is explained in part by fleet operation: whether the firm operates as a for-hire carrier or a private carrier.
