With the continuous advancement of the large-scale, socialization and open construction of colleges and universities, a large number of social vehicles have poured into the campus, which has brought a severe test to the school's road traffic and safety management. In recent years, campus traffic accidents have occurred from time to time, from ordinary scratches to large ones involving life safety, which not only puts forward higher requirements for the management of the school security office (section), but also becomes an important aspect of measuring the comprehensive competitiveness of colleges and universities. The simple campus speed limit sign can only serve as a reminder for speeding behavior, not as a constraint. Therefore, many colleges and universities have begun to introduce a speed measurement feedback system for college vehicles in order to standardize campus road management with the help of modern Internet of Things technology and strengthen the road safety construction of colleges and universities.
According to Article 2 of the Regulations of the People's Republic of China on road traffic management, "The roads referred to in these Regulations refer to highways, urban streets and hutongs (lanes), as well as public squares, public parking lots and other places for vehicles and pedestrians to pass." ”
Therefore, other places other than the above- and other places, such as railway crossings, ferries, government compounds, residential quarters, schools, etc., are not "roads" under the Road Traffic Management Regulations. Vehicle and pedestrian collisions that occur at the above locations and even cause casualties or property damage are not within the scope and normative objects of the Measures for the Handling of Road Traffic Accidents.
If a vehicle or pedestrian collision casualty or property damage accident occurs on the internal road of the school, the public security traffic police will not go to the scene to deal with it, and it is usually handled by the school's security department. If it is really necessary for the public security traffic department to assist in the investigation, the public security organ will assist in handling it, and the school can also entrust the traffic police department to deal with it, but the main communication, coordination and handling work is still undertaken by the school security department.
The main reason for the accidents on campus is the accident
1. The road surface of the old campus is narrow, and the trees on both sides of the road are more lush, blocking the line of sight, and for some road emergencies, the driver cannot make predictions and reactions in time.
2. The road surface of the new campus is wide and flat, there is no traffic light, the driver is subjectively paralyzed, and it is easy to speed and drive in the opposite direction.
3. Pedestrians, bicycles, electric vehicles, tricycles, motor vehicles are mixed, do not travel according to the provisions of the road, side by side, chase and other phenomena are very common, it is very easy to cause road traffic accidents.
4. During the class period, during some large-scale cultural and sports activities, events and assemblies, the density of crowds and traffic flow is large, and the management personnel of the campus security department are limited, which cannot be orderly and channeled in time, which is easy to cause congestion and rubbing accidents.
5. There are security patrols on the campus during the day, and perhaps the speeding of vehicles can be curbed, but the attention of many drivers driving at night is obviously insufficient, and there are great hidden dangers to the safety of students traveling at night.
6. The campus road management function is assigned to the school security department, but the security department does not have the corresponding law enforcement power, and cannot deduct driver's license points, fines and other penalties for speeding vehicles, illegal vehicles, illegal parking vehicles, etc., and the deterrent power of vehicle drivers is obviously insufficient.
In order to ensure the traffic safety of teachers and students, reduce campus traffic hazards, purify the campus traffic environment, and effectively supervise driving behavior, a university in Anhui Province has installed a vehicle speed measurement feedback system on the main traffic road of the campus.
Campus vehicle speed measurement feedback system
According to the decision of the school's office meeting, the school will punish illegal parking, speeding and other traffic behaviors on campus: the speed limit of motor vehicles in the hospital is 20km/h, and speeding is strictly prohibited. Where the violation is made for the first time, an SMS reminder is to be given, a notice of the violation is posted, and registration is made for the record. In the case of cumulative violations of 2 times, the system automatically stops the vehicle identification authority of the camp gate for one month.
Campus speeding penalty notice board
The speed measurement feedback system of college vehicles is mainly composed of speed measurement radar, capture camera, speed measuring pole, LED display, control host and storage device.
Mainly installed on the main road of the campus, personnel through the dense area, accident-prone area, etc., the data collected by the speed measurement system includes vehicle speed, license plate number, speed measurement time, speed measurement location, etc.
The information collected is transmitted to the roadside LED display through the network cable or serial port to inform the driver of the real-time speed of the vehicle and remind the speed; the second is transmitted to the storage device of the school security monitoring center computer room through optical fiber to store the data; the third is to push it to the school access control fee management system in real time to achieve speeding statistics, and implement illegal warnings, control access, and even blacklist serious speeding vehicles.
Among them, the speed measurement radar adopts the TBR-100 flat-panel speed measurement radar of Weitai technology. Two radars are installed above the main road of the school, detecting the real-time speed of the two-way single-lane car at the 20m trigger position, and synchronizing the detection data to the LED display on the side of the road.

Based on the microwave Doppler effect, the TBR-100 can detect the speed of the vehicle driving by at the trigger position, and link the camera to identify and capture vehicle information such as license plate number.
When the speed is lower than 20km/h speed limit value, the LED display shows the green speed value (as shown in the figure above), and the radar linkage camera recognizes the license plate number; when the speed exceeds the speed limit value, the red speed value is displayed, reminding the driver to control the speed, and the radar linkage camera recognizes and captures.
TBR-100 main product features
1. The speed measurement is accurate, and the speed measurement accuracy is -4~0km/h.
2. The trigger is precise, and the trigger position accuracy is less than 1m.
3. The consistency of the position of the captured vehicle is high, and the vehicle capture rate is as high as 99%.
4. It has good environmental adaptability and stability, and is almost unaffected by illuminance, dust and wind, rain, fog, snow and other weather and climate.
5. Compared with video detection technology, the detection is not affected by conditions such as luminosity and climate, and does not require daily maintenance such as lens cleaning.
6. Compared with coil detection technology, the installation does not destroy the road and obstruct traffic, and can be directly installed on the gantry or pole, which is easy to install and maintain, with long service life and low cost.
In addition, TBR-100 has passed the inspection and evaluation of the Safety and Police Electronic Product Quality Inspection Center of the Ministry of Public Security, and obtained the "Measuring Instrument Type Approval Certificate" and the "Measuring Instrument Type Evaluation Report" of the National Tachymeter Type Evaluation Laboratory (Public Security), which can be used as the basis for traffic management departments to capture and collect evidence for illegal speeding in highways, intercity highways, urban trunk highways, urban and rural low-grade highways and other traffic accident-prone areas.
TBR-100 main specifications
In addition to the TBR-100, the TBR-310, a side-mounted microwave radar for traffic information detection, is also suitable for university speed measurement feedback systems. Different from the TBR-100 road-side installation, the TBR-310 is generally installed on the side of the road.
In addition to all the above TBR-100 product features, trigger capture and system fusion, the TBR-310 can also detect multiple vehicle targets in 1 to 4 lanes, with functions such as anti-multi-target parallel interference.
