The thesis analyses the effect of an increase in speed on energy consumption, pollutant emissions and railway operating costs. Besides focusing on the direct consequences of speed variation, the analysis also considers ...
El comportamiento a fatiga de las mezclas bituminosas es de vital importancia para el diseño de pavimentos. Como componente que cohesiona la mezcla, el ligante hidrocarbonado influye fuertemente en esta propiedad de la ...
El constante crecimiento de la urbanización de las ciudades hace necesaria una continua expansión de los servicios públicos municipales hacia las zonas recién urbanizadas. El coste del mantenimiento de las infraestructuras ...
Taxis are a necessary mean of transport in cities for meeting the mobility needs of its citizens. The impact of the taxi market in the daily life is quite important, concerning both financial (e.g. taxi drivers' salaries) ...
Traffic congestion is a major source of inefficiencies in metropolitan freeways (e.g. productivity loss, energy waste, pollutant emissions, among other externalities). Active traffic management (ATM) strategies are used ...
Building a high-speed line requires significant investment and its design strongly influences the operation, with the aggravating circumstance that subsequent modifications not initially planned are not always feasible at ...
The relationship between the railway network and the city system has been the subject of numerous studies in recent decades. The railway has assumed great importance as a key element of transport infrastructure for the ...
Over the past 30 years, high speed railway in Europe has experienced a great development due to, among other things, the reduction of travel times, the increase of frequency and the continuous improvement of service quality. ...
The contemporary networks of towns and cities continue to emancipate themselves by embracing ever larger territories while shaping their interstices in heterogeneous mosaics of settlements and open spaces of variable ...
The informal settlement’s associated predicament must be addressed by concurrent remediation and prevention urban policies. Nevertheless, the growing social pressure to respond to the situation through decent and effective ...
The Ground Penetrating Radar test applied to road engineering is overall used to determine the geometric characteristics of the pavement structure by analyzing the wave in the time domain. On many cases, it is often used ...
Asphalt mixtures cracking is one of the most common deterioration mechanisms in flexible pavements. This phenomenon is due to both the application of loads and the degradation of the material as a result of its exposure ...
The use of bituminous material milled from the pavement (known as Reclaimed Asphalt Pavement, or RAP) in the manufacture of recycled bituminous mixtures is growing day by day due to the economic and environmental benefits ...
This doctoral thesis analyzes the impact of the creation and implementation of transport infrastructures, specifically high-capacity road axes, on the territory and the welfare of the population with a marginal approach: ...
Investments in major transport infrastructure projects involve a significant mobilisation of economic resources both for construction and operation. In these projects, to assess the efficiency of the resources used, ...
Traditional design procedures of asphalt mixtures are based on volumetric parameters and the compliance with certain mechanical and functional properties, and do not provide minimum requirements in terms of cracking ...
This PhD thesis aims to analyse and verify the tense and intense relation that is established between the architecture, civil engineering and art worlds. Such analysis is conducted not only in a formal manner, but also at ...
The illegal on-street parking is one of the traffic elements that has more effect in urban environments provoking the presence of bottlenecks in the different roads and, consequently, facilitating the appearance of congestion. ...
Cities face problems influencing urban mobility, such as traffic growth, congestion, explosive population growth, urban sprawl. According to the literature, traffic, congestion, and urban development have an interrelationship ...
(English) The objective of this research is to delve into the decision-making processes that shape the provision of transport infrastructure. To this end, it analyses the historical evolution of transport networks in ...
