Involving Infrastructure as a Latent Variable in Active Transportation Mode Choice: The Case Study of Baghdad City

Abstract

Infrastructural developments have been implemented with the objective of promoting active transportation as a sustainable transportation mode, including the construction of cycling and walking routes and the improvement of existing infrastructure. The impact of this factor on ridership has been a subject of research, and the incorporation of this variable into mode choice models has also been contemplated. Nevertheless, road users’ perception regarding the utilization of these infrastructures has yet to be investigated. Accordingly, this research aims to examine the role of infrastructure provision for walking and cycling as a Latent Variable (LV) in the transport mode choice of high school students in Baghdad City, where this subject has not been previously addressed. A self-designed questionnaire was employed to collect the requisite data. The Integrated Choice and Latent Variable (ICLV) models have been designed and the results demonstrate that the time and cost of trips have a significant impact on the choice of transportation mode. Furthermore, the provision of walking and cycling infrastructure has a notable effect on the choice of walking and cycling for transport. The sub-models indicate that the provision of cycling fences and pedestrian bridges are the most significant variables. Consequently, it is recommended that these results be considered in the provision and improvement of cycling and walking infrastructures to promote active transportation.
