Design of Urban Traffic Guidance Identification System at Tumen Section of West Second Ring Road in Xi’an

At present, the problem of traffic congestion in China is serious, but the corresponding traffic management control is far from meeting the demand. This paper takes the Tumen Section of Xi'an second ring road as an example to analyze the traffic congestion in this section. With the aid of real-time traffic big data, the traffic-oriented signage system is constructed through data processing, congestion assessment, and signage guidance. The system provides drivers with more intuitive and accurate navigation information in a timely manner, which improves the timeliness and accuracy of decision-making in the traffic control department and alleviates the problem of urban traffic congestion.
