English title:	Characterization of overtaking cyclists on rural roads in Spain using instrumented bicycles.
Spanish title:	Caracterizaci�n de adelantamientos a ciclistas en carreteras convencionales de Espa�a mediante bicicleta instrumentada
English abstract:	In Spain, the presence of cyclists on rural roads is very common. he reasons for these trips are of a sporting and recreational nature. The most important interaction that occurs between bicycles and motor vehicles on conventional roads is the overtaking maneuver. Differences in speed, volume and level of protection can compromise the safety of cyclists, who are the most vulnerable road users. Under the Bike2lane research project, a methodology has been developed to collect data on interactions between cyclists and drivers using GPS instrumented bicycles, VIRB Elite video cameras, perceived level of risk device and laser . Overtaking data were collected on five stretches of conventional roads with different geometric and traffic characteristics. In this experiment, the number of cyclists forming the group of instrumented bicycles and their configuration in line or in parallel have also been varied, thus more than 2000 overtaking maneuvers have been recorded. The results show that the methodology is valid to characterize the analyzed phenomenon. From the data obtained, the effect of several factors related to the road, the number of cyclists in the group and their configuration, as well as factors related to the overtaking maneuver itself have been analyzed.
Spanish abstract:	En Espa�a la presencia de ciclistas en carreteras convencionales es muy habitual. Los motivos de estos desplazamientos tienen car�cter deportivo y recreativo. La interacci�n m�s importante que ocurre entre bicicletas y veh�culos a motor en carreteras convencionales es la maniobra de adelantamiento. Las diferencias de velocidades, de volumen y nivel de protecci�n pueden comprometer la seguridad de ciclistas, que son los usuarios vulnerables. Bajo el marco de proyecto de investigaci�n Bike2lane se ha desarrollado una metodolog�a para tomar datos de interacciones entre ciclistas y conductores mediante el uso de bicicletas instrumentadas con GPS, c�maras de video VIRB Elite, pulsadores para el nivel de riesgo percibido y distanci�metros/veloc�metros l�ser. Se han tomado datos de adelantamientos en cinco tramos de carreteras convencionales con diferentes caracter�sticas geom�tricas y de tr�fico. En este experimento tambi�n se ha variado el n�mero de ciclistas que forman el grupo de bicicletas instrumentadas y su configuraci�n en l�nea o en paralelo, de esta manera se han registrado m�s de 2000 maniobras de adelantamiento. Los resultados muestran que la metodolog�a es v�lida para caracterizar el fen�meno analizado. A partir de los datos obtenidos se ha analizado el efecto de varios factores relativos a la carretera, al n�mero de ciclistas que forman el grupo y su configuraci�n, as� como factores relativos a la propia maniobra de adelantamiento.
