Traffic Impact Assessment (TIA) Case Study
Traffic Impact Assessment (TIA) Case Study
Commercial Building Development – Dhaka, Bangladesh
🏗️ Project Overview
A detailed Traffic Impact Assessment (TIA) was conducted for a proposed commercial building development in Dhaka, Bangladesh. The objective of this study was to evaluate the impact of additional traffic generation from the proposed development on surrounding road networks, intersections, and parking facilities.
The project is located in a high-traffic urban corridor of Dhaka, where existing road capacity is already under pressure due to rapid urbanization and increasing vehicle demand.
📍 Project Location
Dhaka, Bangladesh
Urban commercial corridor with high traffic congestion
Proximity to major arterial and collector roads
🏢 Project Type
Commercial Building Development
Mixed-use (Retail + Office Space)
⚠️ Project Challenge
The proposed development was expected to generate a significant number of additional vehicle trips during peak hours. The surrounding road network already experiences congestion, particularly during morning and evening peak periods.
Key challenges included:
High background traffic flow in adjacent corridors
Limited road capacity during peak hours
Parking demand uncertainty
Potential increase in intersection delays
Safe access/egress design requirements
🔍 Study Methodology
The following technical assessments were carried out:
Classified traffic volume count (PCU/day)
Peak hour traffic analysis
Intersection capacity and delay analysis
Trip generation forecasting
Parking demand estimation
Access road impact evaluation
Future traffic projection (5–10 years horizon)
📊 Key Findings
The study identified the following:
Significant peak hour congestion near the project access point
Existing intersections operating near or above capacity
Insufficient initial parking provision for projected demand
Increased delay at nearby junctions during peak periods
Potential queuing impact on adjacent road segments
🛠️ Recommendations
To mitigate the identified impacts, the following measures were proposed:
Redesign of entry and exit points to improve traffic flow
Provision of adequate on-site parking based on demand analysis
Traffic circulation plan within the site
Signal timing optimization at nearby intersections
Dedicated loading/unloading zone to avoid road blockage
Implementation of a traffic management plan during peak hours
📈 Project Outcome
After implementation of recommended mitigation measures:
Improved traffic flow efficiency around the project area
Reduced risk of congestion caused by site-generated traffic
Enhanced road safety for vehicles and pedestrians
Compliance achieved for planning authority review requirements
Improved accessibility for future users of the building
🧠 Technical Value of the Study
This Traffic Impact Assessment ensured that the proposed development is traffic-safe, compliant, and sustainable, while minimizing negative impact on the surrounding urban transport network in Dhaka.
The study also supported approval processes under relevant planning authority requirements.
