Why the Elderly Do Not Travel: An Analysis Based on the 2017 NHTS Data

Published in CICTP, 2023

This paper is about the factors analysis for elderly based on 2017 National Household Travel Survey(NHTS) data. We found elderly have few travel and most of them travel for health.

Exploration of the Characteristics of Elderly-Driver-Involved Single-Vehicle Hit-Fixed-Object Crashes in Pennsylvania, USA

Published in Applied Sciences, 2024

This paper is about elderly drivers hitting fixed object crashes. We found hit-fixed-object crashes in complex environment caused less severe which implies that elderly drivers might drive more carefully.
