Cooperative in-vehicle advice: a study into drivers' ability and willingness to follow tactical driver advice

Motorway traffic congestion is a problem in today’s society. Driver behaviour is a factor that ca deteriorate traffic flow in nearly congested traffic. Traffic flow efficiency may be improved by an in-vehicle system that advises drivrs on their speed, gap, and lane choice. The system’s effect depends on its penetration rate and drivers’ compliance with the advice. This thesis describes a user-survey, driving simulator experiments and a real road study to assess drivers’ ability and willingness to use the systm and follow advice messages. Results show a general ability to follow given advice messages. Factors are identified that may reduce drivers’ willingness to follow the advice and adopt the system.
