Barry’s Bay Intersection Traffic Flow and Geometric Design Optimization

Optimize Barry’s Bay intersection traffic flow & geometric design for efficiency & safety. Expert solutions for smoother commuting.

Introduction:

The Barry’s Bay Intersection, situated at the confluence of Opeongo Line (Highway 60) and Bay Street (Highway 62) in Ontario, Canada, plays a vital role in the community and region. This comprehensive traffic study analyzes the intersection’s geometric layout, traffic flow patterns, and safety measures to identify potential improvements.

Methodology:

• Data Collection: 

• A four-day turning movement traffic count survey captured detailed traffic volume and movement data for six vehicle classifications across all six intersection approaches.

• Traffic Analysis: 

• The collected data underwent rigorous analysis, revealing temporal traffic patterns, peak hours, and congestion trends.

• Existing Conditions Assessment: 

• A thorough evaluation of the current intersection layout, signage, signalization, and control mechanisms was conducted.

• Scenario-Based Performance Evaluation: 

• Utilizing traffic data, various scenarios were simulated to assess performance metrics like delays and traffic flow efficiency under different circumstances.

• Feasibility Study of Layout Modifications: 

• Proposed layout modifications were evaluated based on their impact on traffic performance and geometric feasibility.

• Geometric Design Layout Development: 

• A detailed geometric design layout for the proposed improvements was prepared, incorporating considerations for traffic lanes, signage, signals, turning radii, and pedestrian facilities.

Key Findings:

• The existing intersection layout generally performs adequately.
• Proposed modifications with additional right-turning lanes on the South Approach showed marginal traffic flow improvements.
• Two main layout options were considered for geometric enhancement:
  • Option 1: Adding a right-turning short lane on the South Approach.
  • Option 2: Enhancing turning radius and geometry.
• Option 2 emerged as the preferred choice for its significant geometric improvements, alignment with design standards, symmetry preservation, and space for future expansion.

Recommendations:

• Implement Option 2, the enhanced geometric layout, for improved traffic flow and future adaptability.
• Consider detailed geometric design aspects for the chosen layout.

This study provides valuable insights for enhancing the Barry’s Bay Intersection’s traffic flow and safety while ensuring future growth and development. Implementing the recommended geometric improvements will contribute to a more efficient and user-friendly transportation network for the community.
