Transportation Impact Analysis - Catherine & Mary Street Development

A comprehensive transportation impact assessment analyzing a proposed mixed-use development at the intersection of Catherine Street and Mary Street. This detailed study evaluated the transportation implications of a major development featuring townhouse condominiums (100 units), general office space (150 employees), high-rise apartments (250 units), and a shopping center (5000 sqm). The analysis employed advanced transportation modeling techniques including trip generation using ITE regression equations, trip distribution analysis, future background growth projections, and traffic assignment with full intersection diagrams showing approach volumes and turn movements.

Collaborated as part of a two-person team (Group 25) to conduct comprehensive transportation impact analysis. Applied ITE trip generation regression equations to calculate peak hour trips for four distinct land uses. Performed detailed trip distribution analysis determining directional traffic flow percentages at the intersection with totals of 1517 entering and 1517 exiting trips. Calculated future background growth using TMC growth factors for 7-year projections across all approach directions. Developed normalized trip distribution percentages ensuring accuracy with 100% totals. Created comprehensive traffic assignment diagrams showing existing TMC1, site-generated trips, and future total approach volumes with detailed turn movement analysis. Prepared professional technical documentation with data tables, calculations, and intersection diagrams.

Successfully completed comprehensive transportation impact analysis providing critical insights for development review and infrastructure planning. Key findings included: Trip Distribution revealed North (Catherine St) with 407 entering and 401 exiting, East (Mary St) with 266 entering and 383 exiting, South with highest volumes at 541 entering and 468 exiting (35.7% and 30.9% distribution), and West with 303 entering and 265 exiting. Trip Generation calculations showed AM Peak totals of 328 trips and PM Peak totals of 684 trips across all land uses, with Shopping Center as the primary generator at 110 AM and 417 PM trips. Future Background analysis projected growth across all approaches with 7-year factors applied to existing TMC1 volumes. Traffic Assignment diagrams illustrated complete intersection operations with approach volumes of 571 (north), 340 (south), 355 (east), and 476 (west) for total future conditions. The analysis demonstrated strong collaboration skills and technical proficiency in transportation engineering, providing stakeholders with data-driven recommendations for traffic management strategies, intersection improvements, and development approval decisions.
