Solar traffic lights are signalling devices powered by solar panels positioned at road intersections, pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green), using a universal color code .
Smart highways and smart roads [1] are highways and roads that incorporate electronic technologies. They are used to improve the operation of connected and autonomous vehicles (CAVs [2]), for traffic lights and street lighting, and for monitoring the condition of the road, as well as traffic levels and the speed of vehicles.
LinSig was first written in the mid-1980s as a DOS-based tool for analysing and optimising single traffic signal junctions. The use of the software spread mainly by word of mouth within the traffic signals profession becoming widely used by signal engineers. The LinSig traffic modelling was based on standard 'Y' value hand calculations [4 ...
Aug. 15—RIPLEY COUNTY — Indiana Department of Transportation contractor Five Star Company plans to begin work later this week on Ind. 129 near Cross Plains in Ripley County. Starting on or ...
InSync adaptive traffic control system is a real-time adaptive traffic control system that enables traffic signals to immediately adapt to traffic demand. MASSTR (Meadowlands Adaptive Signal System for Traffic Reduction) located in the Meadowlands Region of northern New Jersey will incorporate over 128 signals when complete. As of June 2013 ...
Trailer-mounted variable-message signs are used to alter traffic patterns near work zones, and for traffic management for special events, natural disasters, and other temporary traffic patterns. The messages displayed on the sign can be programmed locally on the unit's control panel, or units equipped with a cellular modem can be programmed ...
The busy T-shaped intersection of Kindig Lane and High Street was converted to a signalized intersection on Tuesday morning.
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.
