Environmental and history research encompasses stormwater best management practices; ecology, including mitigation of animal-vehicle collisions; endangered species; waste management in VDOT maintenance operations; and the identification and management of historic and cultural resources in VDOT right of way, especially structures.

Planning research encompasses transportation planning at the state, regional, and local levels; socio-economic forecasting; access management; trip generation; transit research; bicycle and pedestrian studies; and performance measures.

Economics research includes return-on-investment and benefit-cost studies for improved materials and practices, transportation finance, and innovative funding approaches for transportation.

The VDOT Library provides online access for agency employees to a very large number of e-books and full-text materials available from subscription databases; circulation services for items the Library owns, including PE exam preparation materials; inter-library loan services; quick answers to reference questions; and customized technical literature searches by a professional librarian.
