Dynamic Eco-Driving

By PSU EcoMerge Capstone - 4:14 PM

Surface transportation consumes a vast quantity of fuel and accounts for about a third of the US carbon emissions. In addition to the use of more fuel-efficient vehicles and carbon-neutral alternative fuels, fuel consumption and carbon emissions can be lowered through a variety of strategies that reduce congestion, smooth traffic flow, and reduce excessive vehicle speeds. Eco-driving is one such strategy. It typically consists of changing a person's driving behavior by providing general static advice to the driver such as: not accelerating too quickly, reducing overall speed within reason, not carrying excess cargo, etc. Dynamic eco-driving is a strategy where advice is given in real-time to drivers in changing traffic conditions within the vehicle’s vicinity. This dynamic strategy takes advantage of real-time traffic sensing and telematics, allowing for a traffic management system to monitor traffic speed, density, and flow, and then communicates advice in real-time back to the drivers. By providing dynamic advice to drivers, approximately 10-20% in fuel savings and lower carbon emissions are possible without a significant increase in travel time. Based on simulations, it was found that in general, higher percentage reductions in fuel consumption and emission occur during severe compared to less congested scenarios. Real-world experiments have also been carried out, showing similar reductions but to a slightly smaller degree. More information.

In the current climate of rising fuel costs and tight margins, any strategies for reducing fuel consumption must be a key priority for all logistics operators. By linking driving behavior with positive environmental outcomes, the opportunity exists to significantly reduce fuel consumption and costs.

The key benefits of the Eco-Drive™ program include:

Cost Savings - Reducing fuel consumption through behavioural change can cut your fuel bill by up to 20% - that’s hard to ignore

Reduce GHG Emissions - Mitigating carbon pollution by enhancing the behaviour of drivers will cut dangerous emissions

Compliance with Legislation – NGERS legislation institutes a legal imperative to cut emissions – Eco-Drive™ represents an opportunity for a low cost, practical and fast achievement in emissions reduction

Engaging Staff - The program helps drivers and other staff feel part of the climate change solution, not part of the problem - boosting morale leads to longer term commitment
