Urban Road Network Management

Many different organizations are interested in using the area above and below the streets. One of the most important things is to co-ordinate and harmonize the various areas of interest. The purpose of this report is to show who decides how the street zones in cities are used; to show different organizational solutions chosen to share access, and the type of laws that form the basis of this work; to define those who have an interest in using street zones and the conflicts that arise; to show the [...]

International Experiment to Compare and Harmonize Skid Resistance and Texture Measurements

This document presents the International Experiment involving 41 friction and texture measuring devices that operated on 58 locations (including 10 airfield runways) in Spain and Belgium in September-October 1992. The analysis of the results and conclusions bear on correlations between texture measuring devices and friction measuring devices; relationships between friction and texture according to different models; repeatability of each device; reproductibility between devices and a proposal [...]

The Quality of Road Service - "Evaluation, Perception and Response Behaviour of Road Users"

The quality of service is defined as the capability of a product or a service to meet the needs of its beneficiaries (users, residents, elected representatives, road owners and operators, etc.). Their expectations may vary from one country to another depending on specific cultural and socio-economic contexts and it is the policy makers' responsibility to set quality objectives consistent with those contexts. The paper differentiates between two main types of indicators. On the one hand, technical [...]

Planning & Budgeting on Road Network Level - Presentation of Budgets for Decision-Makers

The maintenance of road networks is becoming increasingly important. For this reason we must seek to employ new management systems. Construction and maintenance of public roads are paid by taxpayers. Fundamentally the taxpayer (the road user) has financial responsibility for the system - their interests need to be taken into consideration. The public wants decision-making to be transparent and has the possibility to control the system. The issue as a whole can be seen in the fact that all steps [...]

The Role of Economic and Socio-economic Models in Road Management

In a context where the Public Administrations experience a stronger and stronger demand on social policy, and where road budgets, especially road maintenance budgets, tend to be tightened or even scaled back, the economic evaluation - and optimization - of road maintenance actions and/or policy becomes a recurrent requirement. There is, therefore, a growing need for methods and tools to meet this requirement. The development of such tools implies a number of technical obstacles, including: [...]
