Abstract
Abstract. In this work, we present a framework supported by mobile and web apps and able to propose personalized pedestrian routes that match user mobility profile considering mobility impediments factors. We explain how these later have been defined using a pedestrian-centric approach based on travel experiences as perceived in the field by senior citizens. Through workshops, six main factors that may influence pedestrian route choices were revealed: passability, obstacle in path, surface problem, security, sidewalk width, slope. These categories were used to build digital tools and guide a citizen participatory approach to collect geolocated points of obstacle documented with walkability information (picture, category, impact score, free comment). We also involved citizens to evaluate these information and especially senior referents for validation. Finally we present how we connect these points of obstacle with a pedestrian network based on OpenStreetMap to configure a routing cost function. The framework has been partially deployed in 2020 with limited people due to the pandemic. Nonetheless, we share lessons learned from interaction with citizens in the design of such a framework whose underlying workflow is reproducible. We plan to further assess its relevance and sustainability in the future.
Highlights
1.1 Context and problem statementThe average age of people experiencing discomfort in moving around is 69 years, with a very noticeable increase from 79-80 years of age (Hauet and Ravaud, 2002)
To begin we found good references from other similar projects such as Project Sidewalk to predefine an early typology
The intent is to adopt a pedestrian-centric approach to define an adequate typology of pedestrian mobility impediments by making concrete experiences as perceived in the field by senior citizens
Summary
1.1 Context and problem statementThe average age of people experiencing discomfort in moving around is 69 years, with a very noticeable increase from 79-80 years of age (Hauet and Ravaud, 2002). The unevenness of sidewalks, holes, obstacles (Chaudet, 2012), the absence of benches for resting (Huguenin-Richard, 2014) and the inadequacy of lighting (Chapon and Renard, 2009) constitute obstacles to regular walking. This mode of travel is largely predominant from the age of 70 (Dumas, 2012) and it is essential to the health maintenance of seniors living at home. In order to promote the mobility of senior citizens, it seems necessary to consider actions to make pedestrian travel safer and easier through the appropriate design of the urban environment (Dumas, 2012). We must highlight the fact that sidewalks are increasingly becoming an area of interest in the era of new mobilities and new functionalities linked to the smart city (Baraud-Serfaty, 2020)
