Rhode Island's Strategic Highway Safety Plan was developed as a guiding document for efforts to reduce the number of highway crashes and resulting fatalities and injuries by sharing information, combining resources, and targeting efforts to the areas of greatest need.
RIDOT's State Traffic Engineer serves as the technical advisor to the State Traffic Commission, which reviews requests for traffic control devices such as stop signs, traffic signals and roundabouts. The Commission also reviews other traffic and safety initiaives such as crosswalks, speed limit changes, and striping changes and has the authority to direct RIDOT to peform traffic safety and speed studies, crash analyses, and other traffic-related investigations.
Parade & Event Permit Application
RIDOT has established this permit to streamline the approval process for parades, road races, cycling tours or other organized events on State roads and bridges. Please fill out this application completely and mail to:
The application can also be submitted via Fax to: 401-222-3006 or emailed to: firstname.lastname@example.org.
Applicants should provide any supporting documentation they feel would be important in describing the event. It is the permittee’s responsibility to obtain approval from each city or town the event will take place in.
RIDOT has developed a new approach to identifying and addressing safety and congestion problem locations. Called Rhode Island's Strategically Targeted Affordable Roadway Solutions (RI*STARS), the Department hopes to target locations based on the level of congestion and high crash rates with a systematic and data-driven approach. From this analysis, RIDOT will have the best information possible to determine which projects need to be tackled first.
RIDOT has installed a new type of traffic signal at the corner of Elmwood Avenue and Daboll Street in Providence that has been proven to increase pedestrian safety. Known as a “HAWK” signal, it is the first of its kind in Rhode Island and in New England. Click here to learn more.
RIDOT in April 2012 installed Rhode Island's first flashing yellow arrow traffic signal on Route 3 in Coventry. The signal technology is being adopted at protected-permissive traffic signals to reduce crashes and make left turns easier. Read more here.
RIDOT in Spring 2011 completed two projects aimed at improving nighttime visibility with the installation of reflective markings called roadside delineators along most limited access highways in Rhode Island. The Department also placed additional signage, striping and installed embedded reflective markings at three of the sharpest curves on I-95. Click here to learn more.
RIDOT in Spring 2010 began a street lighting curfew aimed at reducing electrical costs and providing more funds for maintenance of Rhode Island's roads and bridges. This is being accomplished by establishing a lighting curfew during the early morning hours when traffic is lightest.
Traffic Research is responsible for maintaining and updating several of the Department’s primary database and information management systems. These systems are listed below:
Traffic Research is also involved in ITS deployment statewide through contracts for the design and installation of various types of vehicle detection devices such radar, acoustic, fiber optic, piezo-electric and other non-invasive technologies.
Application for a Business Sign
The Application for a Business Logo Sign form and a brochure explaining the program is available here. This is the form that would be used by a business who wishes to advertise their locale with a sign indicating the exit to their location. The application lists all of the qualifications for such a sign and the step-by-step process to obtain one.
Application for Accessible Pedestrian Signals
Accessible sidewalks and street crossings are vital for pedestrians with vision impairments. Accessible Pedestrian Signals communicate information about the time of a crossing using non-visual formats such as audible tones, verbal messages, and/or vibrating surfaces. Read our policy to learn more.
