Integrated Traffic Management Using Data from Traffic, Asset Conditions, Energy and Emissions

Background: Proposed Structure And Elements Of A (Future) Tms

Modern TMS and even more future TMS are receiving or requesting more and more data from different sources. Age, quality and content of those data will be spread more than in past. The Figure 1 shows some of the sources and receivers of information of the TMS in the real-time environment. Naturally the TMS receives the timetable and network structure from the planning and collects data for the later analysis and controlling. The TMS is the core of the integrated mobility management in middle of Figure 1. It receives and sends information to individual customer interfaces as smart phones as well as public ones as the information pages in the internet. On the other side of the middle column it exchanges information with the control, command and signaling systems which are the interlocking and train control systems. Those systems can be trackside or onboard of the trains, too.

Real-time data exchange of the TMS

To make the optimal decision in the case of deviations from the original timetable the TMS has to take into consideration information from many other sources. Four examples are given in Figure 1. The timetables or – if available – the real-time information from other transportation systems have to be used to ensure the best service for the traveler. The maintenance management can deliver information about the status of the infrastructure and vehicles. It will be able in the future to give a prognosis, too. The power and energy management can support the TMS to decide in an energy-efficient way. Finally the interface for collaborative decision making can help to bridge the gap to other decision processes. Therefore the traffic management of public transport systems has to ensure that the transport system delivers the best quality of service to the customer. It has to take into account influences from many sources:

• •

  Customer demand

• •

  Current traffic status of the transport system by the command, control and signaling system

• •

  Asset conditions and predictions

• •

  Power/energy management

• •

  Maintenance management

• •

  Minimized power consumption

• •

  Local reduction of noise and other emissions
