Estimating the Longest Trip for Plug-In Electric Vehicle Households

Long distance road trips are underreported and underestimated in many travel behavior studies. These infrequent trips of several hundred miles account for a non-trivial percentage of vehicle and household vehicle miles traveled (VMT), yet many studies tend to overlook, underreport, or misrepresent them. Overall, for households that own a new plug-in vehicle, a single trip (the longest in the last 12 month) accounts for 10% of the household’s annual VMT for almost 95% of households. In terms of greenhouse gas (GHG) emissions, 10% of the household’s GHG emissions are accounted for by that trip for approximately 90% of households in the sample. The authors explore the variables and characteristics that effect the distance of the longest-trip. They use data collected in California during June and July 2017 as part of a study that focused on plug-in electric vehicle (PEV) households. The authors estimate a log-linear model to understand the factors that influence the length of the longest road trip made in the previous 12 months. The number of household vehicles, the presence of low-range battery electric vehicles, and the number of passengers on the longest trip have the greatest impact on trip-length.
