Project Background
There are 8 public parking lots on the ground where parking management is required in the Olympic Park; they are respectively distributed along the outer entrance passage of the Olympic Park beside the main municipal roads such as Anli Road and the North Fifth Ring; in addition, the main entrances and exits of the parks should also be effective. According to the drawing statistics, there are a total of 26 entrances and exits to be carried out.
Overview of Smart Parking System
A complete parking guidance system consists of four basic components: data acquisition system, data communication system, information release system and central control system. Its working principle is: first collect the relevant information of the parking spaces of each parking lot through the data acquisition system of each parking lot, and send the information to the central control system through the data transmission network according to certain rules, and the central control system analyzes and processes the information After that, it is stored in the database server and distributed to the information publishing system to provide information services. For parking space information in the database server, the system provides a data query interface. It is not difficult to see that no matter which one of the four links is, it is inseparable from the most basic data collection. For the driver, accurate and detailed parking location is the most critical.
Two data collection methods are commonly used internationally: First, set up parking space display equipment at the entrance and exit of the parking lot, upload the data of each parking lot through each entrance and exit management system, and then load it on the remaining parking space display screen of each parking lot. This solution has a low cost. , Cost-effective and accurate. Second, install microwave equipment in each lane to determine the changes in the long section of the microwave to collect data. This data collection method is susceptible to interference, large amounts of wiring, high costs, and too much maintenance. Therefore, according to the actual situation that the roads of the Olympic Park are intertwined and complicated, and microwave detection equipment cannot be installed, our company uses the first data collection method.
The system needs to set up vehicle detectors at the entrances and exits of the park and the entrances and exits of each parking lot. The direction discriminator determines the number of the entrances and exits. The number of vehicles detected by the vehicle detectors is added and subtracted through the counter, and the parking data is uploaded to the local computer. , The local computer uploads the remaining parking space data to the parking guidance management workstation through the construction equipment network. After the parking management workstation downloads the data to the parking guidance display, the display shows the number of parking spaces in the park or each parking lot, and prompts the parking space usage status in the park or each parking lot. If the parking space is full, guide the vehicle to other Area driving or parking.

Parking management demand analysis
Driving guidance management requirements
The Olympic Park has a very large traffic volume. The vehicles entering the Olympic Park can be roughly divided into three parts: working cars in the park, taxis and social vehicles. How to ensure that these vehicles entering and leaving the Olympic Park and the vehicles that pick up and drop off tourists can pass and park in the Olympic Park safely, clearly, and quickly, and effectively guide and manage the safety of these vehicles. As a component of urban intelligent transportation, the parking management system can reasonably arrange necessary parking, increase the utilization rate of parking facilities, promote the balanced utilization of parking facilities in the Olympic Park, reduce on-street parking, reduce waiting for queuing vehicles, and reduce driving The time it takes for operators to find parking spaces, so as to reduce the additional traffic around the Olympic Park brought by parking for tourists. This is the first demand that the Olympic Park needs to solve for vehicle management.
Parking management needs
Parking management demand 1: Vehicle parking fee management demand
The parking lot of the Olympic Park is a fee-paying parking lot; how to improve the work efficiency of toll collectors, save manpower and various social resources, prevent the loss of parking costs and increase management efficiency, and strive to obtain the largest return on investment is the first solution to the parking management of the Olympic Park. Two requirements.
Parking management requirements 2: Vehicle entry and exit and parking safety requirements
There are 8 public parking lots on the ground in the Olympic Park; they are located beside the outer entrance passage of the Olympic Park beside the main municipal roads such as Anli Road and the North Fifth Ring; in addition, effective vehicle entry and exit management should be implemented at the main entrances and exits of the parks. According to the statistics of the drawings, there are a total of 26 entrances and exits to be carried out. These access channels are independent of each other and connected with each other by lanes. The characteristic is that there are many lanes and many bends, and there are many hidden dangers of accidents during the driving of vehicles; coupled with the dense and mixed people of the Olympic Park, it has caused great safety risks to the parking safety of vehicles entering the Olympic Park.
How to solve the safety of vehicle parking management and meet the requirements of Beijing Municipal Transportation Administration for Olympic traffic management. It is necessary to have effective records of vehicles entering the Olympic Park, so that there is a documented investigation in case of an accident. Prevent vehicles from hanging, stolen, man-made damage and personal safety issues when the vehicle owner is parking, and improve the timely handling and response control capabilities when these problems occur, and further ensure that the parking and parking safety issues of vehicles entering the Olympic Park are The Olympic Park addresses the second need of parking management.
