Research that is Essential, Indispensable, and Connected to our Customers.
GDL also helps coordinate the interaction of key players in IHSDM software development, including research contractors, software developers, end-users, and commercial CAD/ roadway design software vendors. GDL markets IHSDM to decisionmakers and potential end-users, and supports staff research related to roadway design and safety.
GDL’s transportation engineering expertise supports the laboratory’s function of reviewing and assisting in the development of the engineering models included in IHSDM for evaluating the safety of roadway designs.
By combining transportation and software engineering expertise, the GDL has the unique ability to evaluate software from both the software developer and end-user perspective.
Communications and engineering skills help the GDL staff to understand the needs of the audience (e.g., design engineers), thereby supporting effective technical assistance to end-users.
IHSDM development is a long-term effort, involving many research contractors, software developers, and Federal Highway Administration (FHWA) staff. In addition, FHWA seeks input from end-users and user organizations to help ensure that IHSDM is responsive to user needs. GDL helps coordinate the interaction of all those involved with IHSDM development.
PRODUCTS AND SERVICES
