A question has been sent out to a structured sample of 732 Chicago drivers to inform about their attitude towards improvements in the motorway system. They got a fictive amount of $ 100, which they could spend as they liked on ten items of roads improvements, one of which could be freely chosen. In general the largest amount of money was spent on repair and improving the pavement. Then came increased enforcement of the traffic rules, and electronic signs to furnish information about traffic conditions ahead. Construction of less or more entrance ramps, or providing traffic report by radio were the lowest placed in priority. The division in subgroups from the respondents gave hardly significant results at the 5% level. Regression analysis yielded no significant correlation either. Information on traffic conditions and the provision of aid telephones appeared to be relatively important to motorway drivers, but not to city street drivers. For them repair of pavement damage was" also highest on their priority list.
