Overview
Traffic congestion, congestion, accidents, and environmental pollution have become the most difficult public hazards in modern society to eliminate. Research on improving transportation has attracted more and more attention from governments around the world and concern from the public. Traffic and parking difficulties have increasingly become a bottleneck restricting the economic development of large and medium-sized cities in my country. Make full use of modern science and technology, and draw on the experience of foreign transportation development processes to introduce urban parking guidance systems, thereby combining soft and hard methods to save huge construction costs and improve parking difficulties.
As an integral part of urban intelligent transportation, the parking system can reasonably arrange parking, improve the utilization rate of parking facilities, promote the balanced utilization of parking facilities, reduce roadside parking, reduce queues of vehicles waiting for storage, and reduce the number of drivers. Reduce the time spent searching for a parking space, thereby reducing the amount of additional parking traffic in the city center.
The urban parking guidance system is jointly developed and constructed by absorbing and digesting foreign advanced technology and combining it with the characteristics of Chinese cities. The system uses advanced/network transmission technology to provide citizens with real-time urban parking information, save drivers time, reduce the blind flow of vehicles caused by the lack of parking information, more effectively improve the difficult parking situation, and increase the use of parking spaces. Rate. As an important part of the urban parking guidance system (intelligent transportation system), European and American countries have conducted a lot of research work and applied it to city centers. In developed transportation countries such as the United States and Germany, it has been promoted in more than a dozen cities. Through the use of parking guidance systems, urban traffic congestion has been greatly alleviated, road occupation has been reduced, vehicle exhaust emissions and noise have been reduced, and the original efficiency has been significantly improved. There is a high utilization rate of parking facilities and good social and economic benefits have been achieved.
By drawing on advanced transportation construction and management experience at home and abroad, Xiamen’s parking lots and parking spaces are unified managed through mobile networks, and vehicles entering the area are induced in real time to provide convenient and timely parking services for the parking crowd. The parking space information allows users to find a suitable parking space by taking the shortest route in a short period of time, thus reducing the number of cars cruising in public road spaces looking for parking spaces.

1. System Introduction
Project Introduction
Xiamen is a commercial, In order to create a comfortable, low-carbon and friendly urban environment in a city characterized by human settlements and tourism, it is imperative to use advanced technology to build an intelligent parking guidance system. Due to the lack of a parking guidance system, motor vehicle drivers are unable to see, hear, enter or exit the parking information. Therefore, electronic parking guidance systems should be established as soon as possible in some areas with heavy traffic congestion to effectively alleviate the problems of parking and driving difficulties. In order to alleviate the current traffic congestion, it was decided to introduce advanced high-tech equipment and use mobile networks to induce parking on important main roads in Xiamen. Parking guidance signs are set up in important commercial areas and major traffic arteries in Xiamen City to quickly guide vehicles to parking lots with empty parking spaces and achieve the purpose of easing traffic.

The parking lot transmits parking space information to the service platform through the mobile network
First, set up collectors at the entrances and exits of each parking lot. The data collected by the collectors are transmitted to the microcontroller for processing. After processing by the microcontroller, The data is sent to the router through the serial port, and the router begins to transmit parking space information to the public service platform according to the instructions of the microcontroller
The service platform transmits parking space information to the flat screen on the urban traffic arterial road
The display screen on the urban traffic arterial road actively Request data from the service platform, and the service platform returns the corresponding parking space information to the display screen according to the device's request and dynamically displays it on the display screen in real time

The urban parking guidance system is based on The variable, multi-level information release electronic screen is the main information carrier, providing drivers with the specific location of the parking lot (garage), real-time data of the current parking space and other information, guiding the driver to park reasonably, and at the same time providing data for analysis and auxiliary management. Intelligent transportation systems for sectoral decision-making.
The system consists of data collection, data transmission, central management system and data release system.
Data collection end
There is a data collection end in each parking lot (garage), which senses the status of cars entering and leaving the parking lot at any time, and transmits the remaining parking space data in the parking lot to the management control center. After all the information sent from the parking lot is comprehensively processed by the management control center, these data and comprehensive information are then transmitted to every dynamic sign on the city street, so the information on the parking lot usage in each area and outside the area is real-time. Dynamic.
Data transmission
is mainly divided into two parts
) The interaction between the collector, the display's microcontroller and the wireless router adopts a high-security and high-reliability interaction protocol.
) The parking space data communication between the parking lot information collection terminal and the central management system and the communication between the central management system and the induction screen are recommended because the induction screen is installed on the side of the road and it is inconvenient to lay communication cables. Use wireless communication methods to achieve data communication within the system, such as the /network we use.
The parking space collection terminal transmits the parking space information to the management control center through the /network. At the same time, the management control center transmits the data collected by the vehicle collection subsystem to the space information electronic induction screens on both sides of the urban road through the /network.
The advantage is that
the release system induction screens are placed on both sides of the road in scattered locations
Easy to install and debug
Easy to daily maintenance and inspection
The parking lot is widely distributed. It is more difficult to construct using the wired method
The investment is small and the construction difficulty is low.
Management Control Center (Information Dispatch Center)
The management control center is an entity that summarizes and processes the collection and release of parking lot (library) data. Including several functions such as data collection, data processing and information release.
Data collection uses the communication module to automatically collect parking data (such as current parking space information, parking statistical data, etc.) and road traffic data. Process, make statistics, and analyze the collected parking information, and introduce technology into the urban parking guidance system to edit and query data on streets, parking lots, and other geographical information through electronic maps to achieve graphical analysis of traffic data. layer management.
There are many forms of information release. The most direct one is to release static regional street paths and dynamic parking lot free parking space information to the guidance display screen to provide path guidance and parking space information. This is also the application of this system. main aspects. In addition, we can also realize various release forms such as information release (building parking information website, etc.), construction (customer service center), mobile phone SMS information release, radio station and TV information release, vehicle or handheld display device information release, etc.
The collected parking space information will be transmitted to the guidance screens everywhere in a timely manner, which will bring great convenience to citizens' parking. At the same time, some road condition information and announcements can be released in a timely manner.
The prediction model that uses the relationship between parking space utilization and road vehicle flow predicts the traffic flow conditions in the area. The changes in parking spaces reflect the traffic flow conditions in the area to some extent. By establishing a relationship model between the two, the traffic flow conditions in the area can be predicted. Take measures in advance for information dissemination and inducement.
Intuitively monitor the usage of parking spaces in the city and apply urban electronic maps to the management of parking lots and parking spaces. Based on this, we design an electronic description of urban traffic and a dynamic information release system, integrated transportation network and parking spaces. distribution network. Unified monitoring of parking lot and parking space dynamic information.
Information Release Screen
In the planning and design of induction display screens, the three-level induction idea is generally adopted at home and abroad
The first-level induction display screen is set up on the main traffic arteries in the urban area. A display device that publishes the names, locations, and actual parking space status of multiple parking lots (garages).
The secondary guidance display screen is set up on both sides of the streets in the surrounding area of the parking lot (garage), and is a display device that publishes the name, driving route, and actual parking space status information of the parking lot (garage).
The three-level induction display screen is set up near the entrance of the parking lot (garage), and is a display device that publishes the name of a single parking lot (garage), the actual parking space status and other prescribed information.
Receive various information sent by the management control center through the method and send it to the induction screen in time.
Provide detailed parking information such as parking lot location information and driving direction
Use an ultra-high brightness dot matrix display to display the smoothness of each major road to remind drivers to avoid crowded road sections
