Rather than requiring users to give them information, the city might improve things by providing real-time information about its traffic. This would enable individual users to make their own decisions as to where and when to travel possibly with help from third-party companies who specialize in providing advice. Google, Apple, and the wireless companies may already have a good-enough version of traffic data because they can track people via their phones. There is no need for the government, the organization that fixes the roads, provides the police, administers a court system, etc, to also be in charge of traffic management. It can be handled through the market.
