Trut - information search cost and benefits of traffic information (sweden)

• Benefits from traffic information examined using three methods; focus groups, stated preference-studies (SP) as well as simulated work-trips on the internet. The SP-results show that that there is a clear relationship between message content and the valuation. They also show that the value of decreasing uncertainty, when informed about a travel time delay with ± 10 minutes, corresponds to SEK 3.80 (EUR 0.4). The travel simulation shows that radio messages in general have a larger effect than VMS messages on route choice. Repeated information has however an impact, since a large share of the respondents who did not switch route at the first decision point, switched at the next decision point where updated information was given.
