TrafficPlan.ca – Guided Traffic Control Risk Assessment

  • TrafficPlan.ca Guided Traffic Control Risk Assessment

  • TrafficPlan.ca Guided Traffic Control Risk Assessment

    This Guided Traffic Control Risk & Compliance Assessment is designed to evaluate work zone conditions, identify hazards, and support safe traffic control planning in accordance with WorkSafeBC Part 18 and the BC Traffic Management Manual (TMM 2020).

    This tool provides a structured risk evaluation based on site inputs including roadway conditions, traffic behaviour, worker exposure, and environmental factors.

    The assessment supports decision-making and documentation but does not replace site-specific planning, supervision, or professional judgment.

    All traffic control must be implemented in accordance with applicable regulations and site conditions.

  • Project & Site Information

    This section documents project details and identifies responsible parties for traffic control planning and implementation.
  •  - -

  • Assessment reflects conditions at the time of completion. Changes in site conditions require reassessment.

  • Roadway Characteristics

    Defines roadway type, alignment, and configuration influencing traffic control design and worker exposure.

  • ⚠️ HIGH-RISK TRAFFIC ENVIRONMENT IDENTIFIED

    Multi-lane roundabouts introduce:
    - Lane changing within the traffic stream
    - Driver confusion and missed exits
    - Reduced predictability of vehicle paths

    This configuration significantly increases risk to traffic control personnel.

    Additional controls are required to maintain safe operations.

    WorkSafeBC Part 18 requirements for worker positioning, visibility, and traffic control must be met.

  • Traffic Conditions

    Assesses traffic volume, road users, and operating conditions that influence driver behaviour and control effectiveness..

  • Work Zone Setup

    Defines the type, location, and configuration of the traffic control operation in accordance with TMM 2020 requirements.

  • Worker Exposure

    Evaluates worker proximity to live traffic and level of exposure in relation to active vehicle movements.

  • Environment & Emergency Conditions

    Identifies environmental factors and emergency readiness requirements impacting worker safety and response capability.

  • Emergency Preparedness & Response

    These items do not affect risk score but must be completed to ensure compliance with WorkSafeBC requirements.

  • 🚨 CRITICAL COMPLIANCE FAILURE

    This assessment has identified critical safety deficiencies within the work zone setup.

    🚫 Work should NOT proceed until these issues are corrected.

    The current conditions present unacceptable risk to workers and/or road users, and do not meet minimum safety requirements under WorkSafeBC Part 18.

  • ⚠️ COMPLIANCE GAP IDENTIFIED
    One or more required emergency preparedness elements are incomplete.
    WorkSafeBC requirements are not currently satisfied.
    Work must not proceed until corrective actions are implemented.

  • ✅ COMPLIANCE VERIFIED

    All required emergency preparedness elements have been confirmed.
    WorkSafeBC Part 18 requirements for emergency readiness have been satisfied.

  • Traffic Control Risk Assessment Summary

    Summary of identified risks, required controls, and overall traffic management considerations based on the assessment inputs.

  • Based on the conditions identified during this assessment:

    Key Risk Factors Identified

    • Workers exposed to live traffic
    • Frequent equipment crossings
    • Workers required to cross roadway during operations

    Traffic Safety Considerations

    Appropriate traffic control measures must be implemented to protect workers and road users. Controls may include:

    • Advance warning signage
    • TCP positioning with clear escape routes
    • Additional advance warning signage where equipment frequently crosses the roadway.
    • Supervisor oversight where worker exposure is high

  • Traffic Control Risk Threshold Scale

     

    Risk Score Range 
    Risk Classification
    Operational Guidance
    🟢   0–15
    Low Risk
    		  Standard traffic control measures appropriate
    🟡 16–30
    Moderate Risk
    		 Additional supervision and enhanced traffic control measures recommended
    🟠 31–50
    High Risk
    		 Enhanced traffic control plan required with additional control measures and supervision
    🔴    51+  Critical Risk Immediate safety review required – specialized traffic control measures or redesign recommended

  • Assessment Methodology

    Risk scores are calculated using weighted factors including traffic speed, worker exposure, work zone complexity, environmental conditions, and emergency preparedness. This framework supports hazard identification and aligns with WorkSafeBC Part 18 and the BC Traffic Management Manual (TMM 2020).

  • 🟢 LOW RISK RESULT

    Standard traffic control measures are appropriate for this operation.

    Ensure:
    • Advance warning signage is installed correctly
    • TCP positioning includes clear escape routes
    • Workers remain visible and protected from live traffic

  • 🟡 MODERATE RISK

    This work zone presents moderate operational risk. Standard traffic control measures may require enhancement to ensure worker and road user safety.

    Recommended controls include:

    • Additional advance warning signage where driver reaction time may be limited
    • Increased supervision of traffic control operations
    • Review of TCP positioning to ensure clear escape routes
    • Enhanced channelization to guide traffic safely through the work zone
    • Monitoring of traffic speeds and driver compliance

    Where conditions change or worker exposure increases, additional controls should be implemented.

     

  • 🟠 HIGH RISK

    This work zone presents a high level of operational risk and requires enhanced traffic control planning and supervision.

    Additional safety measures should be implemented prior to commencing work.

    Recommended actions include:

    • Development of a formal Traffic Management Plan (TMP)
    • Increased advance warning signage and improved work zone visibility
    • Enhanced channelization and buffer space where possible
    • Dedicated supervisor oversight for traffic control operations
    • Evaluation of equipment crossing points and worker exposure areas
    • Consideration of additional traffic control devices or personnel

    Work activities should be reviewed carefully to ensure that worker exposure to live traffic is minimized.

  • 🔴 CRITICAL RISK

    This assessment has identified critical risk conditions within the proposed work zone.

    Immediate safety review is required before work proceeds.

    The current conditions may present unacceptable risk to workers or road users without additional controls or redesign of the traffic control strategy.

    Recommended actions include:

    • Immediate review of work zone layout and traffic control measures
    • Implementation of enhanced traffic control protections
    • Engineering or traffic management consultation
    • Modification of work methods to reduce worker exposure
    • Consideration of lane closures, detours, or specialized traffic control systems

    Work should not proceed until appropriate safety controls have been implemented and verified.

  • Regulatory Alignment

    This assessment aligns with the hazard identification principles outlined in WorkSafeBC OHS Regulation Part 18 and the BC Traffic Management Manual for Work on Roadways (TMM 2020).

  • TrafficPlan.ca Safety Assessment Tool

    This assessment is intended to support hazard identification and traffic control planning.
    Final traffic control decisions must be made by a qualified person familiar with site
    conditions and applicable regulatory requirements.
