Clients’ expectations from RSAudit • SANRAL wants findings for high and extreme risk
Clients’ expectations from RSAudit • SANRAL wants findings for high and extreme risk • Clients want design check • Clients want to pass risk to the auditors • Consultants want design check • Road safety assessment as part of audit
Practical engineering questions • What to report if there is no safety risk: good design • What to report if the design report adequately explains the design exemptions • What to report if the design standards are known to be high (SSD based on h=0. 15)
Personal preferences of auditors Auditors • Are human • Have personal experiences • Have specific knowledge • What is yours? ? ?
Personal preferences of auditors Slipways and intersection angles
Personal preferences of auditors Slipways and intersection angles
Personal preferences of auditors Trees next to road
Practical aspects of RSAudit • Site visit relevance and context • What if the existing road is completely redesigned • Extreme hazards to be reported • Separate letter • Maintenance laxities • Road signs and markings • Vegetation
Preliminary design issues 1 • Rest areas • Tourism facilities e. g. Kaaimans lookout • Lay-byes • Vegetation • Landscaping on medians • Mist belts • Access control
Preliminary design issues 1 • Rest areas • Tourism facilities e. g. Kaaimans lookout • Lay-byes • Vegetation • Landscaping on medians • Mist belts • Access control
Preliminary design issues 2 • Auxiliary lanes • Separation of low-speed and high-speed traffic • High-speed two-way traffic • Rural four lane roads: divided or not • Lane widths • Shoulder widths
Preliminary design issues 3 • Lack of recovery area / lateral clearance • Low Fill • Cut with side drain • Culvert head walls • Drainage • Superelevation
Issues relating to roadworks and traffic accommodation • Standards details • Project specific exceptions • Separation of workers • Detours • Delay at one way working
Good practice and standard details 1 • Guardrails: lengths and starts, end treatment • Hazard markers and chevrons • Bridge balustrades and transition from guardrails • Protection for bridge piers • Location of bus and taxi stops • Universal access
Good practice and standard details 2 • Wrong markings • Consistent signage • Signage at T-junctions: line of sight or offset? • Signage at roundabouts • Landscaping on roundabouts • Pedestrians at roundabouts
High risk issues in detail designs 1 • Slipways: high and low speed designs • NMT / pedestrian accommodation at slipways • NMT / pedestrian accommodation at roundabouts • Tapers • Oblique intersections for trucks
High risk issues in detail designs 2 • Ribbon development • Schools • Transitions rural to urban • NMT / Pedestrian facilities • Public transport • Rail crossings
RSAudit response • Lack thereof • Inadequate feedback • No design exceptions registers • No institutional memory of good practice
Way forward? • Sharing information • High standards of design • Ultimately out of work • The End
