About Us

DHC delivers consultancy, planning and research services on integrated transport and related topics to a wide range of public and private sector clients. We start from the perspective of users of systems to ensure that providers deliver sustainable and inclusive solutions adding value to traditional approaches and challenging established practices.

In our projects we try to use the language of transport users wherever possible such as “access to services” and “safe routes to town centres”. Our award winning customer relationship platform The Loop incorporates the accessibility planning approach within new smartphone apps.

Why DHC?

DHC delivers consultancy and research on transport, accessibility, infrastructure and regeneration to a wide range of public and private sector clients. We have pioneered many new approaches taking concepts from theory to practice. DHC has helped to prepare official national guidance for central Government on development planning, planning access to services and organising community and stakeholder involvement in transport delivery.

DHC uses state of the art technology to ensure that solutions are efficient, flexible and progressive. Our pioneering services for accessibility indicators and smartphone apps are increasingly widely adopted by clients and partners.

DHC aims to:

  • Tailor methods and results to the needs of our clients.
  • Deliver products on time and within agreed budgets.
  • Produce high quality output which adds value for our clients.
  • Understand barriers to change, and break down those barriers.

We specialise in projects where:

  • A novel or innovative methodology can be applied to the work, or
  • High level skills are needed to understand and develop new concepts.

Our clients regularly tell us that we provide added value, we identify solutions which can be acted on, and that our commitment and enthusiasm to secure practical delivery sets us apart from other competing organisations.


DHC is built on the skills, enthusiasm, experience and innovation of its staff. DHC can draw on an extensive network of specialists from psychologists to engineers who have worked with us on projects over the two decades years.
