Analysis of the current traffic management in the city of Ústí nad Labem was conducted. It describes in detail the architecture of the existing transport subsystems and their mutual integration and communication, which is not optimal and is often realised via telephone connections of operators of individual subsystems. Data transfer is neither rapid nor complete. Therefore, information may not be available to all or to some of the subsystems of traffic management in required time.
Given the large number of separate subsystems for traffic management, road maintenance, PT operation, parking management, management of the Integrated Rescue System, etc., and their problematic interconnection, the proposed solution for strategic traffic management in Ústí nad Labem was not based on the existing architecture of management systems. The reason was particularly the problematic sharing of traffic information, which optimisation would require significant investments and technological and organizational changes.
The more effective solution is to change the entire traffic management system, which would enable integration of all the existing subsystems and continuous real-time sharing of information. The proposal of new traffic management scheme was based on conclusions of the previous study, specifically in terms of identified shortcomings of the current management scheme. The proposal defines an integrated traffic management system gathering, processing, storing and sharing information among the relevant bodies in the city with centralised management. Entities proposed to be included within the architecture of ITS are primarily administrators of roads, units of the IRS and road users (drivers, pedestrians, cyclists and PT passengers). Surveillance and regulation functions were also proposed to be integrated to effectively eliminate violations of traffic rules.
The proposed solution is designed to contribute to improving the quality of transport in the city, increasing traffic flow, improving road safety and lowering negative effects of traffic in the city, including the amount of accidents, injuries, deaths, material damages, emissions, noise pollution. The impact of the proposed traffic management scheme is essential particularly during emergency events, which in Ústí nad Labem typically result from unfavourable weather conditions, such as floods and winter ice and snow. As a result of improved strategic traffic management, the city is more suitable for development of non-motorised transport (pedestrians and cyclists) and for PT services.
The proposal was integrated into the Sustainable Urban Transport Plan of Ústí nad Labem.
