Traffic estimation and prediction systems (TrEPS) have the potential to improve traffic conditions and reduce travel delays by facilitating better utilization of available capacity. These systems exploit currently available and emerging computer, communication, and control technologies to monitor, manage, and control the transportation system.
A traffic congestion map is a graphical, realtime or near-realtime representation of traffic flow for some particular area. [1] Data is typically collected via anonymous GPS datapoints and loop sensors embedded in the roadways, then processed by computer at a central facility and distributed as a map view to users.
Used to determine the distance headway between a vehicle and its predecessor. One of the simplest model in this category is the Pipe's rule, the basic assumption of this model is "A good rule for following another vehicle at a safe distance is to allow yourself at least the length of a car between your vehicle and the vehicle ahead for every ten miles per hour (16.1 km/h) of speed at which you ...
HERE WeGo can download maps of countries and regions to internal storage so that a data connection is not needed for navigation. Online usage provides live traffic data and additional venue information. [40] The maps include floor-by-floor details of large indoor venues such as shopping malls and airports. [41]
A traffic camera is a video camera which observes vehicular traffic on a road. Typically, traffic cameras are put along major roads such as highways, freeways, expressways and arterial roads, and are connected by optical fibers buried alongside or under the road, with electricity provided either by mains power in urban areas, by solar panels or other alternative power sources which provide ...

In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.
