Abstract
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 19 years. Given that the expected life of a wind turbine is 25 years, thisarrangement is demonstrated to be an economically viable solution. Climate change poses a major challenge to society and opportunities such as thisto reduce CO2 emissions should be implemented to help address this globalissue. (Secondary source).
