Project Structure and Division of Work

The METRASYS project is headed by the Transportation Studies Group at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt in der Helmholtz-Gemeinschaft (DLR)). The German project partners are:

  • Wuppertal Institute for Climate, Environment and Energy (WI),
  • AS&P - Albert Speer & Partner GmbH,
  • Fraunhofer FIRST (FIRST),
  • Freie Universität Berlin (TEAS) and
  • LUAX Software Consultancy.

The Chinese project partners are:

  • Research Centre for Software Engineering Technology (ASEC),
  • Chinese Academy of Transportation Science (CATS) Beijing,
  • Tongji University Shanghai,
  • Chinese Academy of Science (CAS).

On the local level, the following partners are involved:

  • Hefei Municipal Traffic Police Department (HMTPD),
  • Hefei Communication Bureau (HCB),
  • Hefei Department of Communication (HDC),
  • Hefei Environmental Monitoring Center (HEMC),
  • Hefei Institute of Urban Planning and Design (HIUPD),
  • The Local 38th Institute in Hefei (HI 38)

The project work is distributed in four different working areas, each containing several work packages:

 Working Areas in METRASYS

WA 1: Data Acquisition and Set Up of a Geographic Information System (GIS)

Data on the traffic in Hefei as well as data on the land use and emissions will be incorporated into the GIS. The validated data is the basis for the traffic management system, the emission modeling, and the assessment of the political and institutional framework for an alternative transportation system and its financing. Thus, the acquisition, provision and management of qualified, adequate, reliable and resilient data are crucial for the success of the METRASYS project. The GIS will be used for the scenario development and assessment (WA 3). Work Area 1 is headed by TEAS and involves DLR, FIRST, WI, LUAX as well as ASEC, CAS, HIUPD, CATS, TONJII and HDC.

WA 2: Technology Development

DLR, LUAX, FIRST and AS&P are going to develop a Floating Car Data-System (FCD) in cooperation with ASEC, HMTPD and HCD. The system will serve for the measurement of the traffic flows in Hefei. Taxicabs, busses and express busses will be equipped with GPS responders and on-board units. Thus, a large-scale and dynamic measurement of the traffic flows in Hefei is possible. The equipped taxicabs, busses and express busses transmit their GPS position, time, speed and driving direction. On an aggregated level, the transmitted data provides an overview of the traffic situation in Hefei.

For the short term, the live data of the traffic flows in Hefei will be transmitted to the already existing traffic management center of the Hefei Municipal Traffic Police Department, the traffic control laboratory of ASEC and the Radio Anhui station. In the long term, the incoming data will be redistributed to all road users through Digital Media Broadcasting (DMB).

WA 3: Traffic Management

After developing technologies in WA 2, the German and Chinese project partners will evaluate the environmental impacts of the traffic management system in Hefei. For the assessment of the environmental and climate impacts of the traffic management system in Hefei, FIRST and the Wuppertal Institute (WI) will developed traffic emission models and air pollutants dispersion models. The Anhui CDM Technology Service Centre of the Anhui Productivity Promotion Centre (CDM Service Center), Hefei Environmental Monitoring Center and CAS will collaborate in the development of those models. Furthermore, different scenarios will be created and the emission impact of each scenario will be calculated in the models. In conjunction with the scenarios, the feasibility of financing sustainable mobility through Clean Development Mechanism (CDM) will be analyzed. The developed traffic management system is to be integrated into the general transportation planning and transportation policy scheme in Hefei, thus linking climate protection and energy efficiency with other governmental responsibilities.

WA 4: Dissemination

WA 4 focuses primarily on public relations and includes activities aiming at the communication of the project as well as at the dissemination of project results via internet, flyers, presentations and papers. It also includes marketing strategies as well as the dialogue with experts, the scientific community and the public. DLR, TEAS, AS&P and FIRST as well as ASEC, CAS, CATS and TONJII are responsible for WA 4.
