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: auditors detached from project team • audit 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%) 57% 3% 27% 1% 3% 6% 3% Vehicle Factors (13%) 20 Source: HSM Chapter 3 Figure 3-3
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
