    This report is the final report of project VERT (evaluation of the bicycle as a feeder mode to rail outside urban areas). The VERT project aims at studying bicycle use as a feeder mode to railway stations, for regular use, in exurban areas. It focuses first on a state of the art fostered by international and French experience, providing quantitative and qualitative elements for research (T2), second on economic analysis (T3) implemented in several modeled scenarios (T4), making it possible to compare bike and ride solutions with park and ride solutions, and to draw a cost-benefit analysis for users and the community. Third, project includes qualitative analyses (T5) backed by interviews with stakeholders, and is applied in a case study in Amboise (T6), comparing scenarios for developing the bicycle as a feeder mode to train, built from observations of present situation, software development to map catchment areas of bicycles and pedelecs,analysing feeder routes and computing the cost-benefit balance of bike and ride. This very positive balance as well as other results show that the Amboise site possesses characteristics enabling this intermodal development, that are supported by some local stakeholders' projects. This confirms that this intermodal potential must be backed by local policies, as shown by experience in other regions or in other countries.Ce rapport est le rapport final du projet VERT (le vélo évalué en rabattement dans les territoires). Le projet VERT vise à étudier l'utilisation du vélo comme mode d'accès aux gares, pour un usage régulier, dans le milieu périurbain. Il se concentre sur un état de l'art nourri d'expériences étrangères et françaises, fournissant des éléments quantitatifs et qualitatifs pour la recherche (T2), sur un bilan économique (T3) mis en oeuvre dans plusieurs scénarios modélisés (T4) permettant de comparer les solutions de vélo+train à des solutions de voiture+train, et d'en établir un bilan économique pour l'usager et pour la collectivité. Le projet inclut aussi des analyses qualitatives (T5) appuyées par des entretiens avec les acteurs, et comporte une étude de cas sur le terrain d'Amboise (T6), comparant plusieurs scénarios de développement du vélo en rabattement sur la gare, construits à partir d'observations de la situation actuelle, du développement de logiciel cartographiant les zones atteintes par le vélo et le VAE (vélo à assistance électrique), analysant des itinéraires de rabattement et établissant un bilan économique de l'intermodalité vélo-TC. Ce bilan très positif et les autres résultats montrent que le site d'Amboise possède des caractéristiques permettant de développer cette intermodalité, confortées par les projets de certains acteurs locaux. Cela confirme que le potentiel de cette intermodalité doit être appuyé par les politiques locales, comme l'ont montré les expériences d'autres régions ou d'autres pays

    A simple method to retrieve the complex eigenfrequency of the Earth's nearly diurnal-free wobble; application to the Strasbourg superconducting gravimeter data

    International audienceWe have analysed more than four years of data from the Strasbourg superconducting gravimeter to retrieve the period and damping of the nearly diurnal-free wobble (NDFW). The removal of noise spikes is found to be crucial for an accurate determination of tidal-wave amplitudes and phases. A new simple algorithm is derived which allows an analytical solution for the NDFW pertod and damping using the complex gravimetric factors of three resonant diurnal waves. The results show a huge reduction of the confidence intervals when compared with a previous investigation from a Lacoste Romberg spring meter operated at the same station. Our results are in close agreement with values obtained from two other European superconducting gravimeters. The results are also compared with respect to values inferred from very long baseline interferometry (VLBI) measurements

    From international experience to French case studies, PORT-VERT, a French research project investigating various possibilities of bicycle-transit intermodality

    The PORT-VERT research project aimed at investigating bicycle-transit intermodality. After a selective state of the art, and the analysis of German best practices, the project explored technical and organizational aspects, socio-economic analysis and behavioural surveys, architectural aspects, ergonomics (as regards on board loading), and the involvement of multiple players. Finally, case studies in Marne-la-Vallée and Rouen were considered. The main results stated that to develop bicycle-transit intermodal use, the entire transport chain must be improved: the bicycle and its use, public transport (networks, stations, rolling stock) and intermodal facilities and services such as bicycle parking near stations. There is no single solution; individual contexts and potential for increase must be considered. An application study was carried out in Marne-la-Vallée for one Parisian suburban train station serving a large university; it showed how estimated potential use varies with different hypotheses with regard to local or global supporting measures

    The PORT-VERT project: a multi-facetted investigation of bicycle-transit intermodality

    The bicycle-transit intermodality, that refers to bicycle and transit use in a single trip, could contribute to increase car-free travel as it overcomes the bicycle’s limited range and the fact that public transport does not provide a door-to-door service. This paper presents some results of a multidisciplinary investigation of this complementary aspect, that has not been much considered in France until now, in spite of an actual potential for increase in many areas on various scales (urban, suburbs, interurban). This potential could be exploited in several ways according to the various needs and preferences of cyclists (B&R or R&B, bicycle parking or loading, etc.). As the solutions are location-specific, two case studies have been conducted
