Development of geographic information systems

Geographic Information System (GIS) - a system for collecting, storing, systematizing, analyzing and graphically visualizing spatial (geographical) data and related information about the necessary objects. The term is also used in a narrower sense - GIS as a tool (software product) that allows users to quickly find, analyze and edit digital maps, as well as additional information about objects, such as building height, address, various technical characteristics of the object.

GIS includes the capabilities of database management systems, editors of raster and vector graphics and analytical tools and are used in cartography, geology, meteorology, land management, ecology, municipal administration, transport, economics, defense and many other areas.

The professors of the department developed a GIS of traffic accidents in Gomel.

Transport modeling

Professors of the department are developing a set of engineering solutions for modeling traffic flows for highways. Transport modeling is the process of creating a working model of traffic (transport simulation), corresponding to the movement in real conditions on highways. In simple words, the simulation of traffic flows is a dynamic computer system with virtual movement of cars on the road, which allows you to track all the problems that arise and make decisions to correct them.

Traffic light optimization

In domestic practice, advanced knowledge and experience in the field of traffic control is poorly used. This leads to a loss of time at traffic intersections, reduced road safety, increased fuel consumption and more intense pollution of the environment with exhaust gases. Such intersections must be optimized for the current situation. Currently, in the Republic of Belarus there are no obligatory rules governing the construction of a traffic light regulation cycle. There is educational literature that is not required for use and is not used in practice.

Traffic light optimization is a relatively cheap way to increase traffic safety and efficiency at intersections. You need to pay close attention to this method, since the effect can correspond (and sometimes be large) to expensive events (for example, the separation of pedestrian and traffic flows at different levels).

Professors of the department carry out calculations to optimize the parameters of traffic lights, including coordinated regulation using modern software.

Optimization example:

The object of study is the intersection of Internatsionalnaya and Lenin Ave g. Gomel.

Scientific and technical analysis of accidents,

One of the most important elements of the system of measures to ensure traffic safety is the scientific and technical analysis of accidents, the study of the causes and consequences of accidents.

Each accident assumes individual responsibility for it, the expression of which is an administrative, material or criminal punishment. The establishment of individual responsibility is not possible with a statistical research method. It requires a deterministic study of the causes and consequences of each accident.

An accident assessment is a comprehensive scientific and technical study of all aspects of each accident separately, conducted by persons with special knowledge in science and technology. The examination of accidents requires the involvement of information from various fields of knowledge: jurisprudence, forensic science, medicine, psychophysiology, construction and operation of roads, organization and safety of traffic, and many others.

The teaching staff of the department simulates the actions for calculating the parameters of an accident using specialized software products, which allows us to answer a wide range of questions and reinforce the evidence base when speaking in court as specialists.

Improving the efficiency of passenger transport by regular public transport

Mobility is increasingly becoming one of the main features of modern society. Human life, especially urban life, is accompanied by daily movements over considerable distances. Each citizen is forced to make trips to study, work, to visit, etc., and most often public transport helps to overcome distances. Given the real price of mobility for humanity, public passenger transport is undoubtedly the most cost-effective means of achieving urban mobility, while being accessible to all segments of the population. It provides access to education, medical services, economic activity, and allows all areas of economic life to function effectively.

An important role is played by the quality of services provided by the public transport system, since the average city dweller spends a significant part of his time in it. On the other hand, the quality of service directly depends on the cost. Currently, the passenger reimburses the incomplete cost of the transport service rendered to him. The state pays part of this cost, spending substantial financial resources on it.

The professors of the department carry out a wide range of works to increase the efficiency of passenger transport by public transport. Among them, the following main areas can be distinguished:

• calculation of the average travel distance of the passenger. The average travel distance of a passenger is the main parameter that determines the fare. The professors of the department developed the “Methodology for calculating the average distance of a passenger’s trip on a regular public transport route network based on selective studies of passenger flows”. The technique has been successfully tested over many years when calculating the average passenger trip distance in the regional centers of the Gomel region, Gomel and Mogilev. The technique is patented;
• optimization of the capacity and number of buses with their distribution along the routes of work, taking into account the unevenness of passenger flows - a computer program has been developed that implements the author’s technique (a patent for the program) for optimal fastening of buses of different capacities on different routes, taking into account the unevenness and power of passenger traffic;
• adjustment of the public transport work schedule taking into account the duplication of routes and the need for coordinated work with other modes of transport;
• optimization of the route network of urban passenger transport of regular services, including using macro-modeling programs.
