Analysis of the Influence of Sport Cyclists on Narrow Two-Lane Rural Roads Using Instrumented Bicycles and Microsimulation

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 null or impassable shoulder. Currently, drivers have share interact, affecting safety traffic operation. The possibility overtaking offers an improvement operation, however it can be difficult, meaning greater invasion the opposite lane thus creating more dangerous situations implying higher duration. To analyze phenomenon, field data from instrumented bicycles naturalistic videos collected, then some performance measures characterize operation obtained. increase number manoeuvres obtained observations, microsimulation has been used by adapting model include their interaction vehicles. microsimulator was calibrated validated data. results show that cycle presence decreases vehicle average travel speed increases percent followers delays. Microsimulation study other scenarios help road administrations safely efficiently integrate vehicular roads.
