    • Capacity of a freeway lane with platoons of autonomous vehicles mixed with regular traffic 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (2021-05)
      Article
      Accés obert
      In the near future, autonomous vehicles (AVs) will travel sharing the current freeways with human driven vehicles. The efficiency of this mixed traffic scenario will depend on the ability of AVs to behave cooperatively. ...

    • Effects of low speed limits on freeway traffic flow 

      Soriguera Martí, Francesc; Martínez Josemaria, Irene; Sala Sanmartí, Marcel; Menéndez, Mónica (2017-04)
      Article
      Accés obert
      Recent years have seen a renewed interest in Variable Speed Limit (VSL) strategies. New opportunities for VSL as a freeway metering mechanism or a homogenization scheme to reduce speed differences and lane changing maneuvers ...

    • Empirical findings regarding lane changing activity on Barcelona B-23 freeway 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (Universidad de Oviedo, 2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Lane changing activity is thought to play an important role in the capacity degradation in congested freeways. However, proofs of this negative impact are scarce due to the difficulties in obtaining suitable data. In this ...

    • Freeway lab: testing dynamic speed limits 

      Soriguera Martí, Francesc; Sala Sanmartí, Marcel (2014)
      Text en actes de congrés
      Accés obert
      This paper presents the Dynamic Speed Limit (DSL) experiment that took place in June 2013 on the last 13 km stretch of the B-23 freeway accessing the city of Barcelona (Spain). The DSL system installed on that freeway in ...

    • Freeway lane-changing: some empirical findings 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (Elsevier, 2018)
      Article
      Accés obert
      Lane changing activity is thought to play an important role in the capacity degradation of congested freeways. However, proofs of this negative impact are scarce due to the difficulties in obtaining suitable data. In this ...

    • Freeway traffic experiment - empirical traffic data under dynamic speed limit strategies 

      Sala Sanmartí, Marcel (Universitat Politècnica de Catalunya, 2014-05)
      Tesina
      Accés obert

    • Lane-changing and freeway capacity: a Bayesian inference stochastic model 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (2020-07)
      Article
      Accés obert
      This article presents a new stochastic computational model for determining freeway capacity reduction as a result of lane-changing activity. The probability density function for the maximum flow that can be sustained on a ...

    • Macroscopic modeling of connected autonomous vehicle platoons under mixed traffic conditions 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (Elsevier, 2020)
      Article
      Accés obert
      Autonomous vehicles (AV) will be present in freeways, and they will have to share current infrastructure with human driven vehicles. This mixed traffic scenario needs to be planed and managed. Some research points that an ...

    • Measuring traffic flow and lane changing from semi-automatic video processing 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc (Universitat Politècnica de València, 2016)
      Text en actes de congrés
      Accés obert
      Comprehensive databases are needed in order to extend our knowledge on the behavior of vehicular traffic. Nevertheless data coming from common traffic detectors is incomplete. Detectors only provide vehicle count, detector ...

    • Measuring traffic lane-changing by converting video into space–time still images 

      Sala Sanmartí, Marcel; Soriguera Martí, Francesc; Huillca, Kevin; Vilaplana Besler, Verónica (2019-06)
      Article
      Accés obert
      Empirical data is needed in order to extend our knowledge of traffic behavior. Video recordings are used to enrich typical data from loop detectors. In this context, data extraction from videos becomes a challenging task. ...

    • Microsimulación de platoons de vehículos autónomos conectados en autopistas 

      Oriol, Laura; Martínez Díaz, Margarita; Sala Sanmartí, Marcel; Soriguera Martí, Francesc (Universidad de La Laguna. Servicio de Publicaciones, 2023)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Se espera que los vehículos automatizados y conectados (VAC) mitiguen las actuales externalidades negativas del tráfico rodado, por ejemplo, los accidentes, la contaminación y la congestión. Las razones detrás de estas ...

    • Modeling present and future freeway management strategies : variable speed limits, lane-changing and platooning of connected autonomous vehicles 

      Sala Sanmartí, Marcel (Universitat Politècnica de Catalunya, 2019-10-29)
      Tesi
      Accés obert
      Freeway traffic management is necessary to improve capacity and reduce congestion, especially in metropolitan freeways where the rush period lasts several hours per day. Traffic congestion implies delays and an increase ...

    • Nuevos datos de tráfico en autopista con límites de velocidad variable 

      Soriguera Martí, Francesc; Sala Sanmartí, Marcel; Martínez Josemaria, Irene (2015-09)
      Article
      Accés obert
      Este artículo presenta el experimento con Límites de Velocidad Variable (DSL) que se realizó en Junio de 2013 en la autopista B-23 de acceso a Barcelona. El sistema DSL instalado en esta autopista, así como la alta densidad ...
