Abstract

We report on the adaptation of an immune-inspired instance selection technique to solve a real-world big data problem of determining vehicle incident hot spots. The technique, which is inspired by the immune system self-regulation mechanism, was originally conceptualized to eliminate very similar instances in data classification tasks. We adapt the method to detect hot spots from a telematics dataset containing hundreds of thousands of data points indicating incident locations involving heavy goods vehicles (HGVs) across the United Kingdom. The objective is to provide HGV drivers with information regarding areas of high likelihood of incidents in order to continuously improve road safety and vehicle economy. The problem presents several challenges and constraints. An accurate view of the hot spots produced in a timely manner is necessary. In addition, the solution is required to be adaptable and dynamic, as thousands of new incidents are included in the database daily. Furthermore, the impact on hot spots after informing drivers about their existence has to be considered. Our solution successfully addresses these constraints. It is fast, robust, and applicable to all different incidents investigated. The method is also self-adjustable, which means that if the hot spots configuration changes with time, the algorithm automatically evolves to present the most current topology. Our solution has been implemented by a telematics company to improve HGV safety in the United Kingdom.

Highlights

Despite govern, industrial and societal efforts to improve road safety indicators, traffic incidents still reach unacceptable levels across the globe
Our work contributes to this area by introducing a big data instance selection (IS) method to identify heavy goods vehicles (HGVs) road incident hot spots
We were provided with a large data set containing three months of incidents collected via telematics

Summary

Introduction

Industrial and societal efforts to improve road safety indicators, traffic incidents still reach unacceptable levels across the globe. For HGVs, the emergence of complex logistics and transportation networks has required the widespread use of sensors, tracking devices, and mobile communication equipment to improve performance, economy and safety. These devices constantly gather information of vehicles and their journeys, including safety hazards and driving behaviour. The company is faced with the challenge of transforming millions of data records into actionable knowledge to enhance their business Part of this enhancement involves providing clients with bespoke software products and analytics that detect and manage risks of danger to vehicles tracked.
