The Metropolitan Expressway was first built between Kyobashi Exit in Chūō, Tokyo and Shibaura Exit in Minato, Tokyo in 1962 for the purpose of increasing traffic flow efficiency in the Tokyo Metropolitan Area, thus optimizing and improving the functionality of the traffic system.
Plans for an expressway on the route were first drawn up around 1970, initially in the form of an elevated expressway over the Meguro River between Shibuya and Oimachi. The elevated expressway plan was shelved shortly after, following concerns about environmental issues and local resident protests, but re-emerged in the 1990s in the form of a tunnel plan.
HERE WeGo provides turn-by-turn navigation in both offline and online modes. Users can enter a destination address, landmark, or business name, and then the app automatically calculates directions and distance to the destination. Real-time traffic data (where available) is also factored and used to predict the arrival time at the destination. [34]
The Urban Traffic Management Control or UTMC programme is the main initiative in the United Kingdom for the development of a more open approach to Intelligent Transport Systems or ITS in urban areas. Originating as a Government research programme, the initiative is now managed by a community forum, the UTMC Development Group, which represents ...
Safety standards (irrespective of traffic control) are mandated by OSHA as well as state-level occupational safety departments. A construction traffic control company operates in the same basic way as any other construction company. Companies submit a bid for a job, the lowest bid is accepted (except in the case of disadvantaged companies), and ...
All cross-traffic (and left-turning traffic) is relegated to overpasses or underpasses, so that there are no traffic conflicts on the main line of the highway, which must be regulated by traffic lights, stop signs, or other traffic control devices. Achieving such free flow requires the construction of many overpasses, underpasses, and ramp systems.
Scalable Urban Traffic Control (SURTRAC) [1] [2] is an adaptive traffic control system developed by researchers at the Robotics Institute, Carnegie Mellon University.SURTAC dynamically optimizes the control of traffic signals to improve traffic flow for both urban grids and corridors; optimization goals include less waiting, reduced traffic congestion, shorter trips, and less pollution.
In traffic control, simple and old forms of signal controllers are what are known as electro-mechanical signal controllers. Unlike computerized signal controllers, electro-mechanical signal controllers are mainly composed of movable parts (cams, dials, and shafts) that control signals that are wired to them directly.
