BackgroundIn recent years, with the rapid development of social economy, the contradiction between supply and demand is becoming more and more acute. The traffic control department hopes to use the advanced intelligent transportation system to effectively improve the level of traffic management, alleviate the difficulties caused by the lack of police force, to realize "strengthening the police with science and technology, improve the level of law enforcement, provide a good traffic environment for promoting the development of social economy. The electronic police and traffic security monitoring system is one of the most advanced police training means, play an increasingly important role, especially in the specification of road traffic, public security investigation has made obvious ef...

BackgroundToll-gate is a bottleneck, that normally trigger traffic jam, not only delay passing time, but also increase emissions of CO2 . There for, all over the world transportation departments require to adopt non-stop electronic toll collection system （ETC）,to stabilize the traffic flow. ETC toll-gate equipped laser detector, for vehicle plate recognition, using electromagnetic induction lamp technology to confirm vehicles information, also used to detect vehicle model, peccancy, owner's information, balance etc. ETC keeps road clear, reduce passing time .RequirementsToll data time ≤0.5sToll gate sends system parameter to lane average waiting time≤60sLane operation data upload to toll gate database time≤1sHigh-reliability, unattended ,MTBF≥10yearsHigh speed data forwarding capabilit...

BackgroundCity traffic guidance system is an important means to enhance the efficiency of city road traffic, the traffic guidance system, through the related technology (such as GIS, GPS, navigation and modern wireless communication technology) integration, effectively guide the running of vehicles, reduce vehicle running time, and finally realize the traffic equilibrium assignment in the whole road network. The effect is mainly manifested in the following two aspects: first, to provide real time route guidance for drivers, so as to avoid getting lost and driving errors, and reduce the rate of traffic accidents; secondly, according to the travel destination of the user, to provide information to the optimization of the route, which is greatly convenient for travelers. This put forward high...

BackgroundIn the application of intelligent transportation, urban public lighting system plays an important role in the whole city transportation, it can protect the safety of pedestrians and drivers. However, to maintain the city's roads and other networks requires a lot of energy and financial resources. Not only that, street lights often consume a lot of energy, but also have a negative impact on the surrounding environment. Therefore, the establishment of a lighting control system is a popular solution, which can help the city government to reduce energy consumption, to achieve a green low-carbon city. The lighting control system comprises a control circuit for controlling lights and each light with a ballast, a network operation protocol, etc.. In order to save costs and energy co...

BackgroundDue to the narrow space, low visibility, complex environment in the tunnel, the security management is difficult. For security, to improve traffic efficiency of tunnel, installed a set of intelligent monitoring system, including fire detector, jet fan, intelligent lightning, signal control, variable information board. When breaking of fire or traffic accident, monitoring system can be used to linkage management center, to evacuate people, upload real situation in the tunnel to help emergency rescue. In addition, set up a control center near to tunnel, for daily management. RequirementsFull GE fiber ports, meet with requirements of video, broadcast, alarm, information and data transmissionAutomatic redundant network connection, ensuring data transmission steadyDifferent traf...
