Description

Technical Field

[0001] The utility model relates to the field of traffic safety and technology, and in particular to an intelligent guidance system for highway reconstruction and expansion. Background Art

[0002] With the continuous development of the national economy, the existing capacity of expressways is no longer able to meet travel needs. Expressway reconstruction and expansion is currently the primary means of increasing expressway capacity. Due to the generally high speeds of vehicles on expressways, insufficient traffic guidance for oncoming vehicles during reconstruction and expansion projects has resulted in accident-prone areas in the areas where expressways are being rebuilt and expanded. Currently, traffic guidance in these areas is mostly achieved through traffic signs and markings and the placement of crash barriers. These methods are limited in capacity and effectiveness, time-consuming, and labor-intensive, and cannot be adjusted in real time to accommodate changing weather conditions. With advances in detection and communication technologies, the highway construction process has become more intelligent. Currently, intelligent guidance technology is primarily used in merging areas where ramps merge into the main line to reduce conflicts and avoid collisions. However, there is no technology designed specifically for intelligent guidance systems in expressway reconstruction and expansion areas. Utility Model Content

[0047] like Figure 1 As shown, the utility model discloses a highway reconstruction and expansion intelligent guidance system provided by the utility model, including a control module, a detection module and a guidance module;

[0048] The control module is connected to the detection module and the induction module respectively, and is used to receive signals from the detection module and output corresponding response signals;
