SKY General information

The SKY Project is a field test of applications already available on the market or coming soon. It is carried out by a large number of ordinary people in real traffic conditions. The SKY project started with several initiatives such as intelligent speed advisory testing with 2,000 participants around primary schools, intersection collision avoidance using V2I with the same number of participants, small children traffic safety using RFID with 300 participants, pedestrian traffic safety using GPS cell phone by 700 participants, hazard warning on winter road by 150 participants, real time probe car data collection by 2,700 vehicles, etc.

This FOT is in order to grasp “user acceptability of Intelligent Speed Advisory”

Pre-simulation / Piloting of the FOT

Method for the baseline

Techniques for measurement and data collection

Collected subjective data: Questionnaire survey and interview.

Availability of data: Contact the FOT contact person.

Recruitment goals and methods

2000 ordinary drivers in their every day car life. Ordinary drivers, Nissan customers, who live in Yokohama city who answered yes with some incentives, free 3 media VICS beacon on-board antenna and free car navigation map database update.

The number of participants, 2,000, was decided on the premise that some participants would never come to the test sites (9 intersections in Yokohama city).

Methods for the liaison with the drivers during the FOT execution

Participants were only asked to answer a questionnaire survey.

Methods for data analysis, evaluation, synthesis and conclusions

Questionnaire survey
