[EN] The presented research used a driving simulator to study the effect of isolated vertical crest curves
overlapped with horizontal curves on driver¿s perception and behavior. The curves were consistent with the
existing ...
Montalbán Domingo, María Laura; Zamorano Martin, C.; Palenzuela Aviles, C.; Real Herráiz, Julia Irene(Hindawi Publishing Corporation, 2014)
The principal causes of cracking in prestressed concrete sleepers are the dynamic loads induced by track irregularities and imperfections in the wheel-rail contact and the in-phase and out-of-phase track resonances. The ...
Llopis-Castelló, David; Camacho-Torregrosa, Francisco Javier; García García, Alfredo(Elsevier, 2019)
[EN] Highway vehicles driving on rural roads account for more than 50% of all CO2 emissions produced by the transportation sector in Europe. Although the policy measures to mitigate Greenhouse Gas emissions are increasing, ...
MOLL MONTANER, SARA; López-Maldonado, Griselda; García García, Alfredo(MDPI AG, 2021-02)
[EN] It is frequent to see cyclists on Spanish two-lane rural roads, both riding individually and in groups. However, these roads were designed only for motorized vehicles, most of them having a narrow section with a null ...
