ITS and renewable energy

This paper examines how the CO₂ cost of implementing and operating some ITS schemes could be almost halved through the use of renewable energy. A case study analysis of an ITS scheme which includes 40Km of Variable Mandatory Speed Limits (VMSL) and road lighting shows that wind turbine generation is a feasible power supply option, with an estimated payback period of 18.6 years. Given that the expected life of a wind turbine is 25 years, this arrangement is demonstrated to be an economically viable solution. Climate change poses a major challenge to society and opportunities such as this to reduce CO₂ emissions should be implemented to help address this global issue.
