Case Study: Vehicle Classified Traffic Count Survey at Syed Nazrul Islam (Bhairab) Bridge

Project Background with Traffic Survey Research Firm AIR Ltd

The Roads and Highways Department, under the Ministry of Road Transport and Bridges of Bangladesh, recently implemented an essential road study. To successfully execute this initiative, Maxwell Stamp Ltd. collaborated directly with our team. Therefore, we conducted a comprehensive Vehicle Classified Traffic Count Survey at the busy Syed Nazrul Islam (Bhairab) Bridge in Kishoreganj.

As a premier Traffic Survey Research Firm, AIR Ltd delivered continuous traffic monitoring, clear vehicle classification, and expert traffic data analysis services for this important national project.

Technical Survey Planning by a Leading Transport Consultancy Firm

To maximize field efficiency and ensure data accuracy, our project management team first prepared a clear traffic survey plan. Because of this, the strategic blueprint clearly defined the survey scope, exact counting locations, timelines, and safety procedures near the Bhairab Bridge road area.

Immediately after completing the planning phase, our research team conducted a careful pre-field check to evaluate real road conditions. Since we identified potential field challenges early, our team calibrated the equipment perfectly ahead of time. Consequently, the actual field operations started smoothly and efficiently.

Basic Team Training for the Vehicle Count Survey

Since large-scale field data collection requires great care, we hired experienced transport survey workers specifically for the vehicle counting tasks. Meanwhile, our core team organized intensive, structured training sessions for all selected workers and supervisors. During these interactive workshops, participants thoroughly learned several key skills:

• Official government vehicle classification standards

• Simple manual and digital traffic counting steps

• High-definition video recording system operations

• Quick data checking methods

• Strict field safety rules

As a direct result of this training process, the field staff maintained very high data quality standards throughout the entire data collection window.

Continuous 72-Hour Traffic Count Operations at Bhairab Bridge

Once the preparatory phases were fully completed, the survey team launched a continuous 72-hour traffic count survey that captured both busy weekdays and weekend periods. Simultaneously, modern video recording systems documented traffic movement in both directions across the Syed Nazrul Islam Bridge.

In addition to standard counts, our field researchers gathered detailed movement data during both peak hours and quiet hours. Therefore, the project generated a highly reliable baseline of traffic information for future road development.

Advanced Data Analysis by Traffic Survey Research Firm AIR Ltd

After completing the extensive fieldwork, our data analysts split the recorded video footage into short 5-minute pieces for careful review. Consequently, each video segment underwent strict vehicle classification across 13 separate categories recognized by the Bangladesh government.

Following this phase, our transport research team analyzed traffic speed, vehicle distribution numbers, and local movement patterns. As a result, the client received a highly accurate, classified traffic dataset perfectly tailored for technical reviews.

Data Grouping and Simple Quality Control Steps

To make the final report highly useful for road planners, we grouped the raw traffic counts into both 15-minute and hourly blocks. Thanks to this structured approach, the project team easily spotted short-term traffic changes alongside broader daily rush-hour trends.

Finally, senior supervisors performed thorough data cleaning and quality checks using advanced verification methods. For instance, they carefully cross-checked vehicle types and corrected any minor errors where necessary. Therefore, the finalized dataset achieved the high level of reliability required for long-term transport planning.
