Conclusion
INTRODUCTION The Traffic Pulse network is the foundation for all of Mobility Technologies® applications. This network uses a process of data collection, data processing, and data distribution to generate the most unique traffic information in the industry. Digital Traffic Pulse® collects data through a sensor network, processes and stores the data in a data center, and distributes that data through a wide range of applications.
Cont. 1.
Sensor network :- heart of the technology
2.
Data streams :- way of processing data
3.
Data transmission :-optical cable, satellite etc.
Sensor Network Def :-A sensor network consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions. They are now used in many industrial and civilian application areas, including industrial process monitoring and control, machine health monitoring, environment and habitat monitoring, home automation, and traffic control.
In addition to one or more sensors, each node in a sensor network is typically equipped with a radio transceiver or other wireless communications device, a small microcontroller, and an energy source, usually a battery. The cost of sensor nodes is similarly variable, ranging from hundreds of dollars to a few pennies, depending on the size of the sensor network and the complexity required of individual

Tools offered by traffic pulse technology * Telematics - for mobile professionals and others, Mobility Technologies traffic information complements in-vehicle navigation devices, informing drivers not only how to get from point A to point B but how long it will take to get there — or even direct them to an alternate route. * Media - for radio and TV broadcasters, cable operators, and advertisers who sponsor local programming, Traffic Pulse Networks provides
