Lesson 6 Practice RSA 6 1 Learning Outcomes

Lesson 6 | Practice RSA 6 -1

Learning Outcomes • 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

Learning Outcomes • Assemble an RSA presentation. • Present the results of the practice RSA to a project owner. • Discuss possible findings and recommendations with project owner. 6 -3

Practice RSA: Before Site Visit • • • (Site Visit Only) Arrange transportation. Gather materials. Gather equipment. Take safety precautions (vest). Wear comfortable clothing. Designate a secretary and photographer. 6 -4

Practice RSA: During Site Visit • • Drive all approaches. Walk site. Observe traffic. Interview road users, enforcement, etc. Note positive safety features. Document with photos. Discuss observations. Think about GORE. 6 -5

Practice RSA: During Site Visit Focus on your team’s road user perspective. • Observe and interview your road user (pedestrian, motorist, etc. ) on site. • Observe and note safety successes and issues for your road user. (Site Visit Only) 6 -6

Practice RSA: After Site Visit • • • Review notes. Assemble photos. Analyze field data. Agree on safety successes. Identify safety issues, prioritize them, and suggest mitigation. • Prepare findings presentation. (Site Visit Only) 6 -7

Example Chambers Rd / State Route 22 Intersection Road Safety Audit Team 3 May 23, 2008 (Sample Presentation: Location)

Project Description and Team Members Example Project Description Analyze the existing intersection of Chambers Rd and State Route 22 to identify potential safety improvements. Assessment Team Scott Parker – Traffic Engineer Jane Hearn – Maintenance Engineer Bob Hammond – Maintenance Engineer Mary Wood – Transportation Engineer Tony Bobbitt – Deputy Sheriff / Traffic Enforcement (Sample Presentation: Objective and RSA Team)

(Sample Presentation: Optional Aerial Photo or Drawing)

Resources and Site Visits Example Resources Information about the intersection was provided by the Bibb County Sheriffs office. Site Visits The 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)

Safety Successes 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 SR 22 was offset (Sample Presentation: Safety Success)

Rating Risk to Prioritize Safety Issues Frequent Crash Frequency Occasional Rare RISK CATEGORY A = Lowest priority F = Highest priority Negligible Low Med Crash Severity (Sample Presentation: Safety Issue and Suggestion) High

EXPECTED FREQUENCY EXPECTED SEVERITY RISK RATING Frequent Moderate C OBSERVATION: Conflicting movements of Chambers Dr to 1 -475 North -bound with the West-bound movement from SR 22 to I-475 North. Example 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 SR 22. (Sample Presentation: Safety Issue and Suggestion)

EXPECTED FREQUENCY EXPECTED SEVERITY RISK RATING Frequent Moderate C OBSERVATION: Poor delineation of Chambers South-bound receiving lane and are non-existent. Example SUGGESTION: Refurbish lane markings and modify the northern most exit from “Circle K” to an exit only. (Sample Presentation: Safety Issue and Suggestion)

EXPECTED FREQUENCY EXPECTED SEVERITY RISK RATING Frequent Moderate D OBSERVATION: The total configuration and geometry of the two intersections are too close together. Pedestrian facilities at the corners are not well-delineated. Example SUGGESTION: Reconfigure Chambers Rd to “Right In – Right Out” only operation. Provide ADA compliant pedestrian accommodations. (Sample Presentation: Safety Issue and Suggestion)

Summary 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.
