: Lane splitting is the practice of riding a powered two-wheelers between lanes when the traffic is slow or vehicles are stopped (Sperley et Pietz, 2010). Although lane splitting is not allowed everywhere in France, it is a common riding practice among motorcyclist drivers. As transport policy is a key driver for promoting sustainable and safe transport, a first experiment (2015-2018) was conducted in eleven departments where a secure form of lane splitting was allowed on highways and urban expressways (Eyssartier et al., 2018). A second experiment is conducted since 2021 in ten new departments with eight specific conditions regulating this practice. The aim of this article is to present the results of this second experiment by analyzing the social acceptability of this road safety policy. This involves studying acceptability and therefore identifying the factors impacting the general attitude towards the measure and the behavioral intention to comply with the rules, based on the Unified Theory of Acceptance a[...]
: The paper presents a model designed to analyse port governance. It considers that thestakeholders ability to adopt cooperative behaviors constitutes the key element to portdevelopment. Its focus is on medium-sized European ports and fifteen cases were studied. Eachterritory was first subject to a qualitative survey and analysis of the contents of local stakeholdersdiscourse (over 80 interviews conducted). The material is rich, allowing for the comparisonbetween two or even three ports, yet the delicate nature of the relations brought to light addsconsiderable complexity to the comparison within a larger ensemble. The paper, therefore,proposes a semi-automatic treatment which helps to mitigate this difficulty by means of acomputer model based on graph theory. It involves a modelling system based on the relationsbetween the entities of the system. In this context, the relations between stakeholders wereanalysed in order to create typologies and eventually envisage some standard models ofgovernance. In order to[...]
