Highway Safety Improvement Program

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.

Work Zone Safety & Mobility

State Traffic Commission

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:

      State Traffic Engineer
      Rhode Island Department of Transportation
      Two Capitol Hill
      Providence, RI 02903

    The application can also be submitted via Fax to: 401-222-3006 or emailed to: ccaouette@dot.ri.gov.

    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.

RI*STARS

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.

HAWK Signal

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.

Flashing Yellow Arrow Signal

Flashing Yellow Arrow

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.


Reflective Markings & Delineators

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.

Street Lighting Curfew

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 Activities

Traffic Research is responsible for maintaining and updating several of the Department’s primary database and information management systems. These systems are listed below:

  • The Electronic Accident Reporting System (EARS) – all annual crash data for the State of Rhode Island is electronically collected from state and local police, stored, processed and analyzed through this system.
  • The Pavement Management System (PMS) – through network pavement data collection efforts, the overall condition of the state maintained road network is tracked, updated and analyzed. The PMS generates an annual pavement rehabilitation / preservation program within the Department’s budget constraints. In addition to the pavement data, Traffic Research staff also collects a video log of state highways that is widely used throughout the Department.
  • The Highway Performance Monitoring System (HPMS) – the HPMS is a federally mandated program that provides an annual report to the Federal Highway Administration (FHWA) as to the status of Rhode Island’s highway network. The HPMS is one of the primary tools used by FHWA to apportion funds to the States.
  • Traffic and Speed Monitoring – this database contains all current and historic vehicle volume, speed, classification, and weight data. This information is used to produce the annual Traffic and Truck Flow Maps.
  • In addition to the managing the above databases, the Traffic Research Section produces several federally mandated annual reports including the Truck Size and Weight Enforcement Plan, The Truck Size and Weight Certification, and the Certified Public Road Mileage.

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.
