Our Company

We have been advising decision-makers on traffic planning and traffic engineering issues since 1998. We support municipalities, public authorities and private companies from conceptual questions to simulations and the implementation of traffic measures. Our understanding of our work is characterised by our roots and proximity to the TU Darmstadt, the application of current methods and tools in transport consulting and a clear customer orientation.
Our work focuses on the optimisation of traffic systems, processes and technologies. We are professionalised at all scale levels: from the regional transport network to the individual intersection, from the overall transport system to individual sub-transport systems. Our approach is to ensure that our solutions are compatible with transport objectives and can be implemented.

Our range of services consists of the consulting fields:

  • Traffic development concepts
  • Traffic engineering analysis
  • Site development and accessibility planning
  • Traffic consultation

The company currently consists of a team of about 25 experienced and young employees with predominantly traffic planning, technical and economic training. Our consistently integrated approach leads to customised solutions, many of which we realise in cooperation with other partners. Independence from any vested interests is a very high priority for us.

We use common macro- and microscopic traffic modelling software (VISUM, VISSIM), work with planning tools for capacity performance calculations and use the usual programmes and geographic information systems (GIS, CAD) to create planning concepts. Overall economic assessments (standardised evaluation, benefit-cost studies) of traffic infrastructure projects (rail/road) and the preparation of mobility concepts are part of our range of services. We conduct traffic counts and organise complex traffic surveys including the evaluation and interpretation of the results.
