This was no mean feat for our developers and work began by taking vehicle location once every three minutes, as is standard in the Zeti Hub, and creating ‘zones’ by plotting the mileage that vehicles had driven to group locations together. When our fleet size expanded into the thousands, we adapted our approach and shifted to hourly GPS data collection, while still retaining access to the more frequent three-minute data, then started incrementally expanding the heatmaps and caching the results, ensuring the heat map remained accurate and responsive. Following this development, we were confident in launching the feature across Zeti Invest and Zeti Operate, allowing users to provide feedback and enabling us to make iterative improvements to the user interface. The customer response to the heatmap since its launch has been overwhelmingly positive and it’s been encouraging to see the likes of Otto Car affirming its value, particularly in discussions with local authorities regarding the improved environmental impacts of their fleet operations. We’re also seeing this positive feedback across the pond in the US, from an American green bank operating under a localized emission-savings mandate in New York City, who expressed great interest in using the heat map to verify the environmental benefits of their financed assets. Looking ahead, the potential applications of the heat map are vast. We are already working on enhancements that will allow us to quantify emission savings, rather than simply categorising them from ‘low’ to ‘high,’ as the current format does. The same principles can also be applied to track reductions in other localised pollutants, such as microplastics from standard tyres. Our collaboration with companies like ENSO Tyres, which are advancing the use of sustainable tire technologies, will enable us to visualise these additional savings geospatially. As we continue to refine and expand the capabilities of the NOx emission-saving heat map, we remain committed to driving innovation that not only meets the needs of our users but also contributes meaningfully to the global effort to reduce emissions and protect our environment.
