Abstract

The Brazilian Urban Mobility Policy integrates urban transport with traffic planning, establishing appropriate public policies that indicate the need for a safe and accessible public transport system. The major challenge is the inclusion of the elderly and people with disabilities. In this paper, we quantify the impact of rainfall on the number of people with disabilities and elderly people who use the public bus transportation system for accessibility in the first and last miles in the city of São Paulo. The proposed methodology is used to evaluate the co-movements between the time series of free-fare users and rainfall in São Paulo. The findings confirm the hypothesis that significant rainfall causes a reduction in the number of daily free-fare passengers who use the public bus system in São Paulo.

Highlights

The Brazilian Urban Mobility Policy integrates urban transport with traffic planning, establishing appropriate public policies that indicate the need for a safe and accessible public transport system
The values found in 28 of the 30 bus lines analyzed using the ρDCCA coefficient were between − 0.50843 and − 0.14394 for boxes of 174 days
For line 1018-10, which showed a positive cross-correlation in a box (n) of 174 days, the result showed that the number of persons with disabilities (PWD) and elderly passengers that ride this line increases with rainfall

Summary

Introduction

The Brazilian Urban Mobility Policy integrates urban transport with traffic planning, establishing appropriate public policies that indicate the need for a safe and accessible public transport system. We quantify the impact of rainfall on the number of people with disabilities and elderly people who use the public bus transportation system for accessibility in the first and last miles in the city of São Paulo. The city of São Paulo, with around 12.8 million inhabitants, stands out due to its strong urbanization over the last d ecades[3], registering an average rate of 0.80% in the period of 2010–2020 This growth directly affects the circulation of its population in urban areas, including via transportation s ystems[4]. The life expectancy of the population has increased because of the constant transformation, growth, and progress of society This means the number of elderly people[8] and persons with disabilities (PWD) has increased[9]. Little attention has been paid to the availability and accessibility of these modes of transportation for PWD and the e lderly[7]
