– on the state of traffic congestion of the road network;

– on the parameters of vehicles (the state of the most critical components and aggregates, speed, congestion, etc.);

– about traffic safety on the route and emergency situations;

– about the environmental situation and the conditions of movement of vehicles depending on the state of the weather and the forecast of its changes;

– about the availability, fuel consumption and location of the nearest filling stations. [66]

For the successful functioning of dispatching and logistics services, the use of the Internet of Things makes it possible to obtain in information systems operational information about the state of transportation with geolocation of vehicles displayed on the map, taking into account restrictions on the movement of certain types of vehicles on highways. [66]

For drivers, the most obvious application of IoT technology is the use of navigators indicating congestion, for passengers – the use of an interactive screen with a public transport schedule. The main advantage is updating these devices online.

Optimal driving routes can be found for motorists due to the fact that data on car speeds in specified areas is processed in the cloud service. This leads to time savings for both drivers and passengers. At the same time, it is possible to reduce the risk of accidents, since there will be less congestion of vehicles.

IoT technologies in the activities of car manufacturers make it possible to significantly improve the work on the release of new models and decision-making on the refinement of existing ones due to the automated collection of a large amount of data on the operation of these vehicles around the world, as well as significantly accelerates the analysis of serial deficiencies. [38] The analysis of the performance of cars and modes of use by drivers of vehicles allows timely release of current software updates, which significantly improves the service provided to consumers.

The introduction of IoT in road transport will allow optimizing the movement of vehicles through analytical algorithms in the network, each vehicle in which is represented as a separate intellectual object. This is necessary for the construction of a new vehicle communication system and the transition from the organization of traffic through intersections through traffic light regulation to intelligent control using wireless communication channels. An alternative option is the use of IoT for intelligent control of traffic light operating modes and the organization of a «green wave» on a section of the road network based on operational data on the structure and capacity of traffic flows. A feature of the application of the «smart traffic light» is the optimal change in the time of the phases of its switching.

Special attention is paid to the organization of prompt and unhindered movement of emergency services to the destination, depending on the current traffic situation, the branching of the road network, the construction of the most rational route, the priority of the movement of these services in the organization of traffic light regulation.

The use of communication between traffic lights reduces fuel consumption and emissions of pollutants into the atmospheric air.

Thus, the introduction of IoT technologies in the automotive industry allows you to reduce congestion at intersections, total travel time, save fuel, reduce emissions of harmful substances from motor transport, reduce the time of emergency services to their destination, organize parking. [72]
