Abstract

Transit access/egress travel is typically considered to be an intrinsic part of the transit trip itself. However, because transit access/egress travel is a major source of nonmotorized travel (NMT), particularly walking, this bundling poses an obstacle to accurately estimating the frequency of walking and biking because it ?hides? access/egress travel inside public transit trips. Using data from the 2017 NHTS Georgia subsample this project examines how to ensure that this hidden walking and biking gets counted. We provide an overview of how access/egress travel is measured in the 2017 NHTS. We then describe our methods for extracting and analyzing instances of walking and biking that are stored in the data as access/egress travel and formatted differently than independent trips. We highlight two key findings: (1) walking is the predominate mode of transit access egress travel and (2) including access/egress travel increases the number of instances of walking and biking by 27.7% compared to using separate trips alone. Incorporating access and egress travel is important to avoid underestimating NMT, particularly among transit-dependent people.

This poster was very insightful and provided important considerations on how we currently analyze access/egress transit trips. Reading through the poster a few comments come to mind: 1. I wonder if there are any local/regional effects that could be unearthed by analyzing and comparing different cities from across the US and the world. Would differences in transit access/egress modes change from city to city just because of differences in the transportation network or are there also social and cultural aspects at play? 2. What could be the reasons for the fact that NMT accounts for three quarters of transit access/egress travel? Are elements such as network composition and layout the main elements at play, or are there other reasons behind this clear prevalence of non motorized travel?
