Tesis doctoral de Thais Rangel Guilherme Christiano
Many countries around the world are seeking new means to involve the private sector in managing and financing infrastructure through public private partnerships (ppps). One of the keys aspects of ppps is to encourage the private sector to manage and operate the infrastructure in the best way. in the last few years, most of the infrastructure management contracts, including ppps, have introduced incentives to encourage the bidders to reach the highest possible level of service, in such a way that any increase in efficiency will be transferred to the users to increase quality. These contracts have usually set up a minimum quality in such a way that if the contractor performs below this quality level, the contractor will be penalized and if they perform above this level, they will be rewarded. this approach has moved many countries such as the united kingdom, finland, portugal and spain to introduce performance based indicators tied to bonuses and penalties in their ppp contracts. these performance based standards often refer to different aspects such as technical, environmental and safety issues. This thesis focuses on indicators that reward the ppp contractor in terms of safety performance in spain. the main aim of this thesis is to identify whether the incentives to improve road safety in ppps are ultimately effective at improving safety ratios in spain. To that end, poisson and negative binomial regression models have been applied using information from the spanish high capacity network in 2006. the results of this thesis show that, even though road safety is highly influenced by variables that are not much controllable by the contractor such as average annual daily traffic, percentage of heavy vehicles and number of lanes, the implementation of safety incentives in ppps have a positive influence in the reduction of fatalities, injuries and accidents.
