Abstract

Many factors make the management of city road networks more complex than the management of rural networks. As matter of fact in the former we have: many type of users, limited alternative routes to avoid temporary obstruction or road closure due to work zone, congestion issues, presence of guideway urban transit systems (e.g. tram and trolleybus), high sensibility towards the environmental issues (noise, vibration, air pollution etc.), town planning requirements, issues related to protection of monuments, etc. In Italy many city administration in order to optimize the road asset management and to improve performance and reduce costs, have ordered the management activity to external service provider by signing global service or concession agreement (see prEN15221-1 06). In these organisation we have three actors: the administration (owner), the manager (service provider internal or external to administration) and the end users. It is responsibility of the administrations to specify the requirements of the management service, which should be aligned to the economic, organisational and strategic objectives defined in the transport policy of the Administration. The most common objectives in urban areas are: accessibility for all users (i.e. vehicles, pedestrian cycle, etc.), safety, environment, transport quality and mobility, asset development and improvement. Once demand requirements of Admistration are clearly expressed the management service can be formalized and ordered through a service level agreement (SLAs). Level of Service is defined through Key Performance Indicators (KPIs), which are used by Administration to ensure that the system move towards the pre-defined goals, and by manager to select maintenance projects, evaluating the impact of each project on level of service. Therefore Performance Indicator are essential element in road asset management activities, delivered by both internal or external provider, as matter of fact in the last decade most international organization and public agency made substantial effort in order to develop criteria for measuring performance. The most significant findings of previous studies suggest, among other things, that that the indicators should be related to stakeholder, structured in quality levels (IQL) and that a relationship should exist between the various stakeholder and the IQL. In the following a framework of indicators to be used in urban areas are illustrated, particularly fixing the attention on the description of the environmental performance indicators.
