Pedestrian environment and route choice: evidence from New York City and Hong Kong

Guo, Zhan / Loo, Becky P.Y.

Highlights ► We model pedestrians route choice in New York City and Hong Kong. ► Route choice is affected by pedestrian environments besides route distance. ► We quantify the monetary value of key pedestrian environmental attributes. ► Route choice modeling is able to assess the intangible environmental attributes. ► Route choice modeling does not work well for a network with few route alternatives.

Abstract To better understand the relationships between walking and the environment, this study tests the feasibility of route choice modeling based on pedestrians’ walking behavior. 321 pedestrians were interviewed in two urban neighborhoods (one in New York City and one in Hong Kong) to identify their actual walking routes. Then, we generated potential alternative routes using a modified labeling approach, measured the route environment through environment auditing and secondary data, estimated two multinomial probit models, and compared the results between the two neighborhoods and between the alternative choice models. It is found that route choice models based on revealed preferences could be a valid and complimentary method for assessing the pedestrian environment, and they could help to prioritize or justify investment related to pedestrian infrastructure. In contrast, contingent rating based on stated preference may overestimate the importance of more tangible attributes, such as distance and safety, because pedestrians were often unable to articulate intangible amenities, such as streetscapes and façade designs. However, route choice modeling seems to perform well only when the pedestrian system offers many route alternatives and pedestrians do have experience with multiple routes.
