| 摘要 |
Generally described, embodiments of the present invention provide systems and methods for gathering and disseminating travel conditions. These conditions may include traffic congestion and air quality data such as CO, NOx, and Ozone (O3) concentration levels, or meteorological conditions. In some embodiments, fleet vehicles already operating within a given area are equipped with monitoring devices to collect the desired data. The collected data may be transmitted to a central computer that associates the data with a road map and disseminates the data to the public. Dissemination may occur in a variety of ways including providing the data to radio stations for broadcast, posting the data on a website or pushing the data to navigation systems in vehicles or mobile communications devices such as cell phones and personal data assistants (PDAs).
