• Perform a practice-RSA of a design-stage or an in-service road.
• Analyze data acquired from site visit or design plans and from other sources to identify safety issues, and develop a set of suggestions to address them.
6-2
• Assemble an RSA presentation.
• Present the results of the practice RSA to a project owner.
• Discuss possible findings and recommendations with project owner.

• Arrange transportation.• Gather materials.• Gather equipment.• Take safety precautions (vest).• Wear comfortable clothing.• Designate a secretary and
photographer.
6-4(Site Visit Only)
• Drive all approaches.• Walk site.• Observe traffic.• Interview road users, enforcement,
etc.• Note positive safety features.• Document with photos.• Discuss observations.• Think about GORE.

• Observe and note safety successes and issues for your road user.
6-6(Site Visit Only)
Focus on your team’s road user perspective.

Project Description and Team Members
Example
ResourcesInformation about the intersection was provided by the Bibb County Sheriffs office.Site VisitsThe assessment team conducted two on site visits:
• May 23, 2008 from 10:00 – 11:00 pm during light traffic•Weather during the site visit was partly cloudy with dry pavement• Assumed this visit was representative of abnormal traffic since the college was not in session
(Sample Presentation: Information Sources and Visit Data)
Resources and Site Visits
Example •Intersection capacity appeared adquate
•Lane assignment signs clearly designated on Chambers Rd.
• Apparently well-lit intersection
• Free flow right turn lane for Chambers Rd.
• Left turn of west-bound SR22 was offset

SUGGESTION: Place a dedicated signal head above the right turn lane for SR 22. Place “Chicken Tracks” separating the two left turn lanes from Chambers Dr onto West-bound SR22.
OBSERVATION: Conflicting movements of Chambers Dr to 1-475 North-bound with the West-bound movement from SR22 to I-475 North.
Example

EXPECTED FREQUENCY EXPECTED SEVERITY RISK RATING
CFrequent Moderate Moderate
SUGGESTION: Refurbish lane markings and modify the northern most exit from “Circle K” to an exit only.
OBSERVATION: Poor delineation of Chambers South-bound receiving lane and are non-existent.
Example

EXPECTED FREQUENCY EXPECTED SEVERITY RISK RATING
DFrequent Moderate Moderate
SUGGESTION: Reconfigure Chambers Rd to “Right In – Right Out” only operation. Provide ADA compliant pedestrian accommodations.
OBSERVATION: The total configuration and geometry of the two intersections are too close together. Pedestrian facilities at the corners are not well-delineated.
Example
Example
•Place dedicated signal head above right turn lane for west-bound SR-22.
•Place Chicken Tracks separating the two left turn lanes from Chambers to west-bound SR-22.
•Refurbish lane markings from east-bound SR-22 to south-bound Chambers Rd.
•Provide ADA compliant pedestrian accommodations for the entire intersection.
