Human Centred Design of a smart phone alert application for drivers
Résumé
Smart phone applications developed to support driving task could be powerful tools to contribute to drivers' safety, eco-mobility and comfort, by allowing real time and quick widespread of critical road information, using geo-location and social networking. Furthermore, downloading smart phone applications is easily accessible at low cost for the drivers. Nevertheless, several issues such as distraction linked to the use of smart phone while driving and reliability of the transmitted information might be critical. In this framework, a survey has been conducted in order to evaluate drivers' usability and acceptability of a collaborative mobile service related to critical road events alert. This analysis showed that drivers are more confident in information displayed by the mobile service than any other sources of road alerts such as radio and variable message signs. Furthermore, senior drivers were motivated to use the mobile service, with a main concern dealing with road safety, and senior participation to the social network in order to generate information to the community was important even if their mileage was lower than younger drivers. Only few drivers recognized some interference with the driving task while using the application. Real road experiments would need to be conducted to evaluate positive versus negative impact of mobile services use while driving.
