Several determinants affect the reason to cycle or not, and some of them are described in a detailed way in the current technical literature review. The recent spread of new modes of active mobility brings up questions for urban transport planners on how to foresee future demand and assess safety conditions; from this comes the need to explore the...

With increasing emphasis on new soft mobility in urban areas, it becomes more and more important to provide effective speed control measures for vehicular traffic. Among those, the ones based on vehicle vertical deflection, namely vertical traffic calming measures, are historically the most widespread. However, since the basic operating principle o...

Pavement maintenance is essential to prevent the deterioration of asset value and satisfy all stakeholders’ expectations. However, the budgets are often insufficient to keep the road pavement at optimum levels. Therefore, a decision-making process ought to be used to prioritize different maintenance activities to optimize the fulfillment of the pre...
Chapter
It is a consolidated knowledge that road macrotexture affects direct primary aspects related to road safety as friction or aquaplaning and secondary aspects related to environmental issues as noise or fuel consumption. These premises highlight how the prediction of road macrotexture is still an open research field for pavement designer, especially...

Objective Given the strong relationship between road accident and traffic speed, the evaluation and prediction of this latter have always been considered as a critical issue for road safety analysis and for the evaluation of road network safety improvements. Prediction models developed to date mainly focused on spot speed in a rural environment or...
Article
Pavement skid resistance, affecting wet-road accidents, deteriorates over time because of material properties, laying conditions, weather/seasonal effects and traffic. Skid resistance deterioration models are critical for design, maintenance and rehabilitation purposes, but very few of them explored the influence of traffic in terms of vehicle type...
