Course Outline:

🟢 Day 1: Introduction to Road Safety and Traffic Impact Assessment

🔹 Global road safety statistics and accident trends.
🔹 Road safety policies, standards, and frameworks (IRAP, WHO, PIARC).
🔹 Fundamentals of road safety audits (RSA) and traffic impact assessments (TIA).
🔹 Key stakeholders in road safety and impact analysis.
🔹 Case study: Analyzing a high-accident corridor and proposing safety measures.

🟢 Day 2: Road Safety Audit (RSA) Process & Risk Assessment

🔹 Stages of an RSA: Feasibility, design, construction, operation, post-crash evaluation.
🔹 Identifying and assessing road safety risks (human factors, environmental influences).
🔹 Crash data analysis and risk assessment techniques.
🔹 Countermeasures: Engineering, enforcement, education, and emergency response (4E approach).
🔹 Site visit simulation: Identifying road safety hazards and proposing mitigations.

🟢 Day 3: Traffic Impact Assessment (TIA) and Modeling

🔹 Traffic flow fundamentals and capacity analysis.
🔹 Impact of road projects on vehicle congestion, pedestrian movement, and public transport.
🔹 Microsimulation tools for evaluating traffic patterns.
🔹 Developing mitigation strategies for minimizing negative traffic impact.
🔹 Case study: Conducting a TIA for a new highway interchange.

🟢 Day 4: Advanced Tools for Safety and Impact Analysis

🔹 Use of GIS and AI in road safety and traffic impact analysis.
🔹 Safety performance functions (SPF) and crash prediction models.
🔹 Application of software: HCS, VISSIM, SIDRA, iRAP tools.
🔹 Non-motorized transport (NMT) safety considerations.
🔹 Case study: Redesigning an urban intersection to improve road safety.

🟢 Day 5: Case Study & Real-World Application

🔹 Hands-on case study: Performing a full road safety audit and impact assessment.
🔹 Group discussion: Best practices for safer road infrastructure.
🔹 Presentation of audit findings and improvement recommendations.
🔹 Course assessment and feedback session.
