ROAD SAFETY AUDIT OVERVIEW
Basic Concepts What is a Road Safety Audit (RSA)? Why do we need RSAs? When do we conduct RSAs? 16
What is a Road Safety Audit? A road safety audit is a formal safety performance examination of an existing or future road or intersection by an independent audit team. 17
What is a Road Safety Audit? formal: procedures and documentation safety performance: focus on safety independent: audit team: auditors detached from project team general experience and specialists 18
A Road Safety Audit also Considers the safety of all road users Examines the interaction of project elements Considers interactions at the borders or limits of the project Proactively considers mitigation measures 19
Why do we need RSAs? Typical Reported Crash Causes Human Factors (93%) Road Environment Factors (34%) 3% 1% 3% 27% 57% 3% 6% Vehicle Factors (13%) Source: HSM Chapter 3 Figure 3-3 20
Why do we need RSAs? Relatively few road-related safety issues are identified in collision reports. Road designs need to anticipate and accommodate common driver/pedestrian/bicycle errors. Easier to design and build safer roads than to modify some entrenched driver/pedestrian/bicycle behaviors 21
Why do we need RSAs? There are many competing interests in the planning and design process: Cost, Environment, Capacity, Safety Compromises are a reality RSAs identify safety implications, safety is an explicit consideration in planning and design, and that safety does not fall through the cracks. 22

FIELD REVIEW RESPONSIBILITIES
Field Review Responsibilities Wear your safety vest! Everyone should take as many notes and pictures as they can! Drive entire corridor, south to north then north to south Walk west and east sidewalks Observe and record pedestrian activity and issues Drive every intersection approach 36
Field Review Responsibilities At each signalized intersection Walk all crosswalks presence and condition of ped/bike facilities Presence of intersection or roadway lighting Intersection sight distance Levels of pedestrian and bicycle activity Interaction with transit Driver/pedestrian/bicycle behavior Record on handout Walk and Flashing Don t Walk timings Phasing Clearance intervals (Y+AR) At each unsignalized (and signalized) intersection Sight distance Proper signage Proper sign placement (not obstructing view) 37
Discussion Corridor issues and opportunities Project goals 38
