swept path analysis

What is a Vehicle Swept Path Analysis?

This is a crucial process used in transportation engineering and urban planning to assess the available turning radius for typically longer and wider loads (Abnormal Loads) that need to access and egress site accesses. (Abnormal loads refer to oversized or overweight vehicles that require special permits due to their size, weight, or dimensions, which may exceed standard legal limits).

Here are the steps Whites Traffic Management Ltd take in conducting a vehicle swept path analysis for abnormal loads:

1. Data Collection: We gather detailed information about the abnormal load vehicle, including its dimensions, weight distribution, wheelbase, turning radius, and any other pertinent specifications.
2. Software Utilization: We use specialised software designed for Swept Path Analysis and using these software tools this allows our engineers to simulate the movement of vehicles and analyze their paths under various conditions.
3. Roadway Data: We acquire accurate data about the road or site where the abnormal load will be transported. This includes information about lane widths, curves, junctions, gradients, obstacles, and any other relevant features.
4. Simulation Setup: We input the vehicle and highway data into the software, setting up the simulation parameters based on the specific route and conditions. Define the starting point, destination, and any critical points along the route.
5. Swept Path Analysis: We run simulations to visualise the path that the abnormal load vehicle will take. We then programme the software to generate detailed diagrams, showing the vehicle's path, including any potential conflicts with obstacles, clearance issues, or areas requiring adjustments.
6. Assessment and Adjustment: We then analyze the results of the swept path analysis to identify potential challenges or conflicts. We then determine if modifications are necessary, such as adjusting the route, obtaining road closures, modifying junctions, or using additional assistance like escort vehicles.
7. Permitting and Compliance:  We ensure that the proposed path complies with local regulations and obtain necessary permits for transporting the abnormal load. This may involve coordination with authorities to address any concerns and obtain required permissions.
8. Implementation and Monitoring: Once approved, we implement the planned route and continuously monitor the movement of the abnormal load to ensure it follows the predicted path and safety measures.

It is important to note that Swept Path Analysis is critical to ensuring the safe and efficient transport of abnormal loads while minimising risks to infrastructure, other vehicles, and pedestrians.

It helps in planning and making necessary adjustments to accommodate the unique characteristics of oversized or overweight vehicles during transportation.
