While my knowledge base doesn't contain specific documentation on incident investigation procedures, safety protocols, and regulatory compliance requirements for traffic control companies following a workplace accident or near-miss event, I can provide general safety guidance based on industry best practices for traffic management plans. A Traffic Management Plan (TMP) is crucial for mitigating the impact of construction, maintenance, incidents, and special events on roadways, ensuring both traffic mobility and worker safety. [3] [2]

Key components of a traffic management plan include:

• Risk Assessment: Identifying potential hazards related to vehicle traffic and work zone conditions.
• Traffic Control Procedures: Written procedures for setting up, maintaining, and removing the work zone.
• Roles and Responsibilities: Clearly defined roles for setting up, maintaining, inspecting, and removing the work zone.
• Work Zone Layout: Flexible layouts that adapt to changing work needs.
• Speed Management: Setting and enforcing maximum speed limits within the work zone.
• Signaling and Devices: Using appropriate traffic control devices and signals.
• Hazard Management: Managing hazards like dust, falling rocks, and potholes.
• Communication Strategy: Informing the public about road work and traffic diversions.
• Incident Procedures: Plans for responding to incidents effectively.

An Incident Management Plan is a sub-plan within a TMP that documents a plan for detecting incidents and managing incident response operations. It includes priorities and procedures for incident detection, response actions that will restore traffic flow as quickly as possible, and a review and analysis process for reducing incident frequency and severity. [4]

Incident Management Plans should define processes for responding to unplanned events or traffic incidents in the work zone so that incident response operations within the work site are managed effectively. [1]

Key elements to include in incident management are:

• Emergency contact information
• Traffic Control Supervisor name and responsibilities
• Traffic Control Manager name and responsibilities
• Types of traffic incidents that could occur within work zone
• Procedures for responding to traffic incident that occurs within work zone
• Procedures to restore traffic flow around incident site as quickly as possible
• Procedures to clear incident and restore normal project traffic operations as soon as possible
• Procedure to inform and update Ministry regarding incident in work zone
• Procedure to inform travelling public of estimated duration of delay and alternative routes (if applicable)
• Incident Reporting
• Investigation Process
• Review and Continuous Improvement Process
