This study uses two different methods, cost-benefit analysis (CBA) and data envelopment analysis (DEA), to assess the socioeconomic impacts of convoy driving on motorways. In the project studied here, convoy-equipped vehicles use a 60-GHz spread spectrum radio to communicate with other convoy-equipped vehicles when the vehicle is about to change lane or speed. The CBA method has been found to be very efficient where costs and benefits can be valued monetarily. DEA is a multiple criteria analysis method that can deal with discretionary or intangible impacts that cannot easily be expressed in monetary units. The results from a study of convoy driving in a three-lane motorway in the United Kingdom show that when the convoy lane is properly fed with convoy traffic, convoy driving may have significant socioeconomic benefits. Both the CBA and DEA show benefits when the percentage of traffic in a convoy is high and the demand of vehicles per hour is great. Omitting an output indicator, as often happens with CBA, may result in underestimation of the efficiency of decision making units. DEA is shown to be applicable to intelligent transportation systems projects which produce multiple impacts, including some that are difficult to measure in monetary terms but can be expressed with quantitative indicators.
