Abstract: In recent years, the geometric multiple growth of the number of cars has put forward new requirements for parking services in expressway service areas. How to effectively use the existing service areas to improve the parking service levels in the service areas, especially during the peak period of holidays, is particularly important. Take China’s expressway west service area as an example, combined with the current status of China’s existing expressway service areas, using monitoring systems such as smart solar spike systems and variable information information boards to effectively monitor and manage the parking lot of the service area, from the area Internal parking space management, parking space occupancy, and vehicle entry guidance are managed to effectively improve the service level of the service area during peak periods.

The expressway service area is an important supporting facility of the expressway. In addition to solving the problems of rest, eating, toileting, shopping, and inquiries, the service area also provides services for passing vehicles, especially long-distance buses and trucks. Service functions such as parking, refueling, maintenance, and accessories. Due to the explosive growth of the number of vehicles in recent years, the site, scale and number of service personnel in the service area have remained at the original level. The random parking of vehicles has seriously affected the service quality of the service area, and at the same time brought potential safety hazards. Therefore, without increasing the service area site, combined with highway traffic flow data, accurate statistics on the number of parking in the service area, combined with information release methods such as variable information information boards along the highway, can effectively guide the traffic flow. It will not be extravagant and wasteful, but can also meet the vehicle service requirements and improve the service level.
This article will investigate and analyze the needs of drivers and passengers and their tolerance flexibility, combined with the spacing of domestic high-speed service
solar stud facilities, and statistics based on the traffic flow of vehicles along the expressway, the number of parking lots and the amount of service area entry, combined with each Calculating the demand for types of services, using the method of successive accumulation of unmet demand, and constraining the elasticity of driver and passenger demand and the operating cost of service facilities, the highway service area parking management plan based on
smart solar studs is proposed to meet the peak period of vehicle parking. service requirements.
The intelligent road stud system of Henan Ruichen Traffic Equipment Co, Ltd. uses the intelligent wireless sensor node P-Node to integrate advanced micro-sensing technology, micro-power processor technology, low-power wireless communication technology, high-efficiency solar energy collection and Management technology to realize effective detection and management of parking spaces. And use the chain wireless network of
the road stud smart node to build an integration and management system for ultra-long-distance roadside parking or ultra-large-scale parking. The system has free scalability, flexibility, and can achieve large-scale at a lower cost Monitoring has great application prospects.
Intelligent solar road studs integrate advanced micro-sensor technology. A single node integrates a three-axis geomagnetic sensor with a minimum sensitivity of 0.5uT and a sampling rate of up to 300Hz.
The solar road stud system can operate normally under low power consumption, and on this basis, there is also an optional sleep state with extremely low power consumption. It also has a very short startup time and can be quickly shut down after data transmission, which also makes the entire system power consumption lower.
Adopting the low-power 2.4GHz wireless transmission technology of the global open ISM frequency band, it has the advantages of ultra-low peak, average and standby mode power consumption, low cost, high reliability, and large wireless coverage. Its low power consumption characteristics combined with high-efficiency self-powered technology can maintain the self-powered operation of sensor nodes for a long time. In addition
, the solar road stud system uses high-efficiency solar energy collection and management technology. It can maintain the detection, collection and wireless transmission functions of the intelligent node for a long time. No need to replace the battery, up to 10 years of working life. Compared with other wireless sensor nodes and devices, this intelligent node has the characteristics of miniaturization and light weight on the basis of powerful functions.
The road studs are easy to install, do not need to damage the road surface of the parking space, and are extremely easy to install and maintain. After the studs are installed, the detection and management of the parking space can be realized at any position in the parking space.
Each smart road stud has a globally unique ID, and contains its own physical location, parking space type, neighboring road stud ID, whether there are vehicles parked and other physical information of the parking space through internal coding.
