Relieving the Congestion around a School via Automatic Vehicle Identification Technology-Based Traffic Measures

Recently, many parents drive their children to and from schools, leading to serious road congestion around the school gate. The school-related congestion is a special type of congestion caused by periodic impulsive aggregation of specific travellers for certain events. In this study, the individual long short-term traffic behaviours were reconstructed based on automatic vehicle identification (AVI) technologies. The cause and countermeasure of congestion around the service centers were identified through the individual behavioural properties. The vehicles that were primarily responsible for periodic impulsive aggregation congestion (PIAC) around the school gate were precisely targeted via a proposed vehicle grading clustering framework. The road management objectives were updated in the AVI data environment and it was found that only 3%–5% of the total number of vehicles passing by the school gate require specific management such as traffic enforcement activities. A series of traffic measures were formulated based on the results of vehicle grading clustering and achieved positive effects in a periodic impulsive aggregation area. It is an effective way to solve the PIAC by formulating management with different activity levels and resolutions for specific travellers. The methodologies and experience presented in this study may provide a useful tool for relieving such special type of congestion around other service centers faced with similar scenarios.

Problems of Vehicle Identification by Tire Marks on the Soil

Scientific research is focused on the problems of vehicle identification by tire marks on the soil. It is argued that the car can either be a participant in a traffic accident or be used during theft of property or kidnapping. The constructional features of the wheels and tires of a car, which are important in the formation of tracks, are described. When the wheel comes into contact with the soil, the tread pattern is reflected. The features of the vehicle tire marks recorded by the investigator and the forensic scientist during the scene search have been determined. Photo or video recording of car wheel tracks is possible, as well as preparing the impression from the display of the tread on the soil. The possibilities of transport and traceological examination for studying the traces of car wheels have been established. The procedure for appointing an expert examination by an investigator is described. There is a list of materials that are provided for an expert study, as well as a list of questions that can be posed to an expert. It is argued that a problem in proving the involvement of a vehicle in the commission of a crime is the possibility of the vehicle tires or wheels to be replaced immediately after it has been committed. Recommendations regarding the identification of a vehicle based on tire marks on the soil are suggested. To establish the fact of changing tires on a car after the commission of a crime, the investigator must seize all sets of tires that are found in the suspect’s household or garage. It is possible to confirm the fact of changing tires on a particular car by interrogating employees of service stations located near the suspect’s residence. In addition to tire marks, to identify the vehicle, it is worth using the testimony of witnesses regarding the model and color of the car, traces of glass debris and paint chips at the accident site and damage on the car itself.
