simTD concept: clearly defined goals.

simTD is pursuing the following principle objectives:

  • Increased road safety and improved efficiency of the existing traffic system through the use of car-to-x communication

  • Definition and validation of a roll-out scenario for the identified functions and applications for scientific questions through practice-oriented experiments and field operational tests

  • Consolidation of car-to-x functions from the categories of traffic efficiency, driving and safety as well as value-added services

  • Definition, analysis, specification and documentation of those functions that are to be developed and tested, as well as of the resulting requirements for the overall system for selected functions and tests within sub-project 1

  • Development of test and validation metrics and methods in each phase of the overall system development in order to allow measurement and evaluation of the results 

  • Consolidation and harmonisation of requirements from the perspective of feasibility and performance as well as their compatibility of requirements within the sub-projects

  • Verification of functions and requirements within the context of individual milestones

During a systematic and methodically sound process, the consortium partners selected the following functions in the categories traffic, driving and safety as well as value-added services. As a first major result, the following functions were selected for implementation:





Monitoring of traffic situation and complementary information/basic functions

  • Data collection in the infrastructure side

  • Data collection by the vehicle

  • Identification of road weather

  • Identification of traffic condition

  • Identification of traffic events/incidents


Traffic (flow) information and navigation

  • Foresighted road/traffic information

  • Road works information system

  • Advanced route guidance and navigation


Traffic management

  • Alternative route management

  • Optimised urban network usage based on traffic light control

  • Local traffic-adapted signal control


Driving and safety



Local danger alert

  • Obstacle warning 
  • Congestion warning
  • Road weather warning
  • Emergency vehicle warning


Driving assistence

  • Traffic violation assistant/warning
  • Traffic light phase assistant/traffic light violation warning
  • Extended electronic brake light
  • Intersection and cross traffic assistance


Additional services



Internet access and local information services

  • Internet-based usage of services 
  • Location-dependent services
