Disabled Pedestrian Level of Service Method for Evaluating and Promoting Inclusive Walking Facilities on Urban Streets

Current analytical methods to estimate the pedestrian level of service (PLOS) usually only consider a narrow range of pedestrians and may not be applicable for more diverse pedestrian populations with different characteristics. The aim of this study is to conceptualize the disabled pedestrian level of service (DPLOS) for different street hierarchies not previously addressed to ensure inclusive walking conditions. An analytical point system comparing existing pedestrian facilities to a standard is proposed to estimate the DPLOS. Although this practical model is only used for one case study in Singapore, the use of international standards would make this model universally applicable.
