By 2014, the top 100 metropolitan areas should have at least 80 percent of freeway and arterial miles enabled by real-time traffic information systems (including incident notification, travel time, and travel speed data), and that information should be available in an interoperable format so that it can be used on any kind of Web, mobile, or in-vehicle application. States should make real-time traffic information freely available to the general public, akin to how the National Weather Service makes weather data available.
In leveraging probe vehicles to collect real-time traffic information, the system should employ government vehicles, taxis, and even private fleets that would want to participate. For example, corporate vehicle fleets include hundreds of thousands of vehicles. If necessary, voluntary vehicles could receive a modest subsidy (such as a slightly reduced vehicle registration fee) for installing the probe device. States with cities in the top 100 metropolitan areas that do not achieve real-time traffic information collection and dissemination on 80 percent of their freeway and arterial roadways by 2014 should be penalized each year with fewer federal transportation dollars.
