Abstract:The major objective of this project is to obtain traffic information from existing wireless
infrastructure.
In this project freeway traffic is identified and modeled using data obtained from existing
wireless cellular networks. Most of the previous research on freeway traffic control assumes the
availability of traffic parameters like vehicle velocity and density. Such data is available only at a
few locations on major highways where sensor nodes have been pre-deployed. In practical terms,
to build a comprehensive network of sensors for this purpose is prohibitive in terms of the cost
involved. However, an existing cellular network of a large wireless provider can be used for
collecting traffic parameter information. As mobile devices have become very common, these
devices can not only provide traffic parameter data but can also be used to receive real time
traffic information using mobile applications. This project uses information obtained from
mobile networks to formulate traffic density models.
