This is one of five fliers that highlight aspects of coordination between Information Technology (IT) and Transportation Systems Management and Operations (TSMO) in transportation agencies. Each flier draws from Principles and Strategies for Effective Coordination of IT and TSMO, a Reference Document.
Challenges in highway construction management and field operations include the lack of real-time and integrated information, gaps between planned solutions and practical implementations, quality assurance, and effective project communications. Three-dimensional (3D) model-based design and construction workflows are becoming more common on highway p

Innovator, published by the FHWA Center for Accelerating Innovation, advances implementation of innovative technologies and processes in the highway industry. Its audience is transportation professionals in highway agencies, trade and research groups, academia and the private sector, and the driving public.
This TechBrief describes an experiment examining the effect of lateral support systems on driving behavior and user acceptance of lateral support systems. The research team used a driving simulator to compare lane-keeping behavior when drivers were controlling the vehicle without lateral assistance (i.e., manual control) or were assisted by lane-de
