Synchronized Mobility

Intelligent transport systems of the future begin to adapt the swarm behavior of animals, using different forms of synchronization to optimize traffic flows and contribute to sustainable mobility developments.

The Saxon high-tech initiative »Synchrone Mobilität 2023« (Synchronized Mobility) bundles the core competencies of both Saxon industry and research organizations. Currently, more than 40 partners are working together to demonstrate innovative research results regarding new vehicle concepts, assistance functions, IT networks, communication, locating and navigation technologies as well as cooperative traffic management in the Dresden area. The city has been selected as model region for automated urban driving.

The research initiative will continue seamlessly the successfully implemented model projects from the recent initiatives »Model region Electromobility in Saxony« (»Modellregion Elektromobilität Sachsen«) as well as »Showcase Bavaria-Saxony ELECTRIC MOBILITY CONNECTS«. Intelligent transport systems are closely related to electromobility with all its ecological advantages, but without neglecting the respective technological limitations. These can be overcome partially by using information and communication technologies in various traffic domains and in the field of charging infrastructure.

Projects

IVS-LOK

Lane-Precise Localization for Intelligent Transport Systems

In addition to vehicle sensors for environment perception and digital maps for navigation, the highly precise and lane-selective positioning of vehicles is an important precondition for automated driving functions. The IVS-LOK project realizes a suitable communication infrastructure for connecting superordinate reference receivers. On the other hand, a network of superordinate reference stations, spread across the entire urban catchment, provides virtual observables and correction data. With this network, it is possible to receive current GNSS corrections and virtual code and phase values for any location within the Dresden test bed. These location-specific data are transmitted to a traffic light system within the corridor, which is equipped with a RSU (Road-Side-Unit).

Fraunhofer IVI Contribution

  • Definition of protocols for the exchange of positioning data
  • Generation of correction data for the planned correction network and deployment of the data as highly precise positioning information via an existing cloud infrastructure
  • Evaluation campaigns with measurement vehicle in the urban Dresden area and rural surroundings
  • Identification of trouble spots using Key Performance Indicators (KPIs) for reproducibility of evaluation campaigns
  • Design of the overall system and vehicle integration
  • Assessment and comparison of various strategies for the supply of reference information from the transport infrastructure to the connected vehicles based on the KPIs
