The Department oversees and administers programs, policies, and regulations to ensure that our transportation system keeps traveling Americans safe while contributing to the Nation’s economic growth. Congress established the Department in 1966 to consolidate more than 30 transportation agencies and functions. DOT employees work across the country in the Office of the Secretary of Transportation, […]
This program guide is designed to support federal agencies developing and refining workplace charging programs for employee POVs. While it provides guidance and best practices, it does not replace agencywide policies or agency-specific legal counsel. This document contains a roadmap for agency workplace charging programs and defines roles and responsibilities. For example, it recommends that […]
State and local transportation agencies increasingly rely on proactive safety analysis to inform roadway design and improvement decisions before crashes occur. However, uncertainty regarding the potential use of proactive safety methodologies, manuals, and guidance in tort litigation has raised concerns about increased exposure to liability. Addressing Liability Issues of Proactive Safety Improvements
Multimodal transportation infrastructure and services are built, owned, maintained, and operated by multiple levels of government and the private sector, supported by a complex mix of interdependent funding and financing sources. This paradigm presents challenges for project development, operations, and service delivery. Navigating this environment requires creative strategies to leverage all eligible resources. Interdependence of […]
The rapid pace of technological advancements is changing how people and goods move through communities. The transportation workforce is adapting to the expansion of emerging technologies that have raised awareness of challenges that are inhibiting the industry’s ability to efficiently and effectively leverage their value. Although every transportation agency’s strategy for workforce adaptation is unique, […]
Motorcycle helmets, specifies minimum performance requirements for helmets designed for use by motorcyclists and other motor vehicle users. FMVSS No. 218 includes three performance test types that have remained largely unchanged since it was first published in 1973: an impact attenuation test, a penetration test, and a retention system test. In 2013 NHTSA initiated a […]
Traffic volume data are used by state departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other local agencies in various analyses and functions related to transportation planning, design, traffic operations, safety, pavement design and maintenance, enforcement, environmental analysis, and construction, among others. Leveraging Existing Traffic Signal Assets to Obtain Quality Traffic Counts
State departments of transportation (DOTs) have effective procurement processes for highway construction but lag in acquiring new business technologies. As they invest in advanced solutions for communications, asset management, and human resources, they aim to leverage artificial intelligence and cloud-based big data tools. However, traditional procurement methods typically relied on by state DOTs focus on […]
State departments of transportation (DOTs) have begun changing the medium of construction contract documents from paper or 2D plans to 3D models that are contractually binding. The driver of this major change is the ability for contractors and inspectors to use 3D models directly to support project activities and communicate the design intent. However, changing […]
Advances in automotive technology aim to enhance traffic safety beyond the capabilities of earlier vehicles. Vehicle technologies have progressed from basic assistance systems to higher levels of automation. As these technologies continue to develop, it is essential to understand how drivers’ perceptions and attitudes toward these systems are evolving. Examining these trends can help us […]
