Traffic Impact Assessment (TIA) Case Study North Star Innovative Ltd.
Traffic Impact Assessment (TIA) Case Study
North Star Innovative Ltd – Knit & Woven Garments Industry, Gazipur, Bangladesh
🏭 Project Overview
A comprehensive Traffic Impact Assessment (TIA) study was conducted for North Star Innovative Ltd, a 100% export-oriented knit and woven garments manufacturing industry located in Tongi, Gazipur, Bangladesh.
The factory is a newly established industrial facility (2024) with a total built-up area of approximately 104,000 sq. ft. The development is expected to significantly increase traffic generation in the surrounding road network, particularly along the Dhaka–Mymensingh Highway corridor.
The purpose of this study was to assess the traffic impact of the proposed industrial operations and recommend mitigation measures to ensure safe and efficient transportation flow.
📍 Project Location
17/3, Sataish Sharak, Gazipura,
Ward 50, Tongi, Gazipur, Bangladesh
Adjacent to Dhaka–Mymensingh Highway corridor
🏢 Project Type
Knit & Woven Garments Industry
Export-Oriented Manufacturing Facility
Industrial Development Project
⚠️ Project Background & Problem Statement
The operation of the factory, along with future production expansion, is expected to generate additional traffic demand due to:
Movement of workers and staff
Freight and logistics transportation
Delivery of raw materials and finished goods
Daily peak-hour commuting activities
The surrounding road network already experiences high traffic congestion and limited capacity, particularly on the Dhaka–Mymensingh Highway.
Therefore, a detailed Traffic Impact Assessment was required to evaluate:
Existing traffic conditions
Future traffic generation (up to 2050 projection)
Road network capacity
Pedestrian movement and safety
Parking demand and transit limitations
🔍 Study Methodology
The following technical approaches were used in this TIA study:
Classified traffic volume count survey
Road inventory and condition assessment
Peak hour traffic flow analysis
Intersection and corridor capacity evaluation
Pedestrian movement and Level of Service (LOS) analysis
Origin–Destination and trip distribution analysis
Parking demand assessment
Public perception survey (willingness and transport behavior analysis)
📊 Key Findings
🚗 Traffic Composition
Three-wheelers (CNG & auto-rickshaw) dominate traffic flow
Approximately 55% of total vehicles are para-transit modes
🚧 Road Conditions
Existing road infrastructure is in poor condition (53.71%)
Footpath condition is also poor (71.14%)
Public transport facilities are inadequate (56.86% dissatisfaction)
🚦 Traffic Performance
Dhaka–Mymensingh Highway carries high AADT volume
Average free-flow speed: ~25 km/hr
Average delay observed: ~2 hours (peak congestion conditions)
Pedestrian flow is very high during morning and evening peak hours
🚶 Pedestrian & Transit Issues
High pedestrian congestion during office hours
Lack of proper bus terminal infrastructure
Transit facilities are insufficient for current demand
📈 Future Traffic Impact
Traffic demand expected to increase significantly by 2050
Existing road network has insufficient capacity for future growth
Additional traffic will further increase congestion in the corridor
🛠️ Recommendations & Mitigation Measures
Based on the analysis, the following measures were recommended:
🛣️ Road Infrastructure Improvements
Development of extended road network capacity
Road widening and junction improvement
🚶 Pedestrian Improvements
Construction and improvement of footpaths
Safe pedestrian crossing facilities
🚌 Public Transport Enhancement
Improvement of bus terminal facilities
Better integration of transit services
🅿️ Parking Management
Structured on-site parking facilities
Proper loading/unloading zone design
🚦 Traffic Management
Traffic flow regulation during peak hours
Improved access/exit design for industrial traffic
📈 Project Outcome
The study concluded that:
Existing infrastructure alone is not sufficient to accommodate future traffic demand
Without mitigation measures, congestion will increase significantly
However, with proper planning and improvements, the project can operate efficiently
The development will contribute positively to economic growth and industrial expansion in Gazipur
🧠 Conclusion
This Traffic Impact Assessment confirms that the proposed industrial development by North Star Innovative Ltd will generate additional traffic load on the surrounding network. However, with the recommended mitigation strategies, the project can operate in a safe, efficient, and sustainable transportation environment.
