Transport Management
New technologies can be used to collect and process real-time information in order to improve traffic flow. One way to use the information is to control public transport. Trendsetter proves that even a few junctions with bus priority systems can have big effects.

The number of roads, junctions, traffic lights and vehicles in large cities can seem never-ending. But it is possible to monitor the actual traffic situation in real-time and then control the flow using that information. This is what modern traffic management is all about. This way, congestion, emissions and traffic volume can be reduced.
Within Trendsetter, Stockholm and Graz have introduced different systems and databases for information collection and exchange. Both cities, as well as Lille and Prague, also try to improve public transport flow by using advanced traffic signal systems or high service bus routes.
Traffic information and controlThe traffic situation depends on congestion, weather, accidents, road works, time of day, etc. Information from different sources and systems about the current situation can be collected and used for traffic management. The collected data also forms a basis for traffic planning overall.
Stockholm has introduced a system for traffic management which will be used to predict the traffic and manage it the best way possible. Several data sources are used and will eventually be connected to a control system for e.g. lane closure, speed advice and traffic signals. This will make the whole road transport system more efficient, which also can have good environmental effects. Furthermore, Stockholm has set up a digital road network where data is linked together and made available.
Graz is also introducing a new traffic management system which includes information from different sources and use different channels to distribute the information. The system was delayed for two years, but is expected to reduce emissions and congestion due to better traffic flow.
A common experience from Stockholm and Graz is that it takes longer than planned to build a traffic management system. One reason is that the system is technically complex and dependent on so many sources. Another reason is the large number of involved stakeholders.
Improving public transport flowBuses that get stuck in traffic jams cause irritating delays for passengers and make it harder for drivers to keep the timetable. One solution is a control system that gives buses priority at intersections. This reduces delays at traffic lights and increases the average speed. Another solution is high level service bus lines.
Dynamic bus priority systems have been introduced in Stockholm and Prague within Trendsetter. The systems are based on computers at major traffic crossings that optimise the priority for every bus arriving at the traffic lights. For buses in Stockholm, the travel time has decreased 15–20 percent and for cars 10 percent due to the installation of the new system at eleven intersections. In Prague, five traffic lights have installed the new system and the reliability of the bus service is now 100 percent. The speed for buses has increased as well as the number of trips with public transport. The quality of service is considered to be very high. Emissions and energy use are reduced as well.
A high service bus route in Lille Metropole has made public transport more popular among commuters and reduced the car traffic in the city centre. The buses have priority at crossroads and the reduction in travel time is estimated to 20 percent. Twelve routes are expected long-term.
Graz has introduced new technology on trams and buses in order to manage and control public transport better. The vehicles have been equipped with on board computers so they can be located and a control centre has been renewed.
