Intelligent Road Traffic Solutions and Technologies – A Review of Research Field

Intersections, lane assignment and care of pedestrians are some of basic challenges of road traffic in and around the big cities. Classic solutions, made a many decades ago, based on priority right rules and time-managed schedule using traffic lights, are not enough satisfying, and quantity of vehicles is faster than development of road infrastructure. In order to decrease air pollution, traffic congestion and number of cars in the cities, there is necessary to invent and implement new approach to passenger-car interaction. Internet of Things and intelligent traffic solutions are trying to solve these problems using new smart technologies in autonomous driving, such a Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) technologies and protocols based on fast communication using DSRC (Dedicated Short-Range Communication) or 5G, within AI (Artificial intelligence) in the background. Number of these solutions were researched, simulated, presented, published, or even patented in last 10-15 years. Goal of this paper is to make review of relevant research works – architectures, requirements, challenges, solutions, but also proposal for the improvements or for new development in direction of optimizing traffic efficiency and safety.
