| This paper is a contribution to the research on the application of information technology to road traffic. An empirical investigation of road use is analysed. It is argued that road users’ communication is essential in achieving co-ordination. This has troublesome implications for the design of artificial driving technologies. An artificial driver must be able to function in a social situation and communicate with other individuals in a shared road space. However it seems that road users co-ordinate their driving through situated activities which take account of the particular details of each situation. This would make road use more difficult to formalize and implement in an AI-system, than if it were understood as merely rule-following activity. |
