- Abstract
- Cyclists’ riding comfort, related to pavement texture and unevenness, has not been thourougly investigated, partly due to the lack of condition assessment methods specifically adapted to the speed and space limits on cycle paths. Metrics that better describe the perceived comfort of cyclists, rather than that of car users, are needed. In this paper a novel method, the Bicycle Measurement Trailer (BMT), is proposed to bridge this gap. Eight different cycle path surface types have been assessed with regards to pavement texture and for four of these surfaces the longitudinal evenness was assessed. The accuracy and repeatability of the BMT were evaluated. Finally, five different metrics (Dynamic Comfort Index, Evenness Coefficient, 0.5 m... (More)

Eight different cycle path surface types have been assessed with regards to pavement texture and for four of these surfaces the longitudinal evenness was assessed. The accuracy and repeatability of the BMT were evaluated. Finally, five different metrics (Dynamic Comfort Index, Evenness Coefficient, 0.5 m Straight Edge, International Roughness Index and Root Mean Square), were calculated from the collected data and assessed. The main findings suggest that the BMT has a high accuracy at normal and high cycling speeds and a high level of repeatability at normal cycling speed. The surfaces could be ranked according to texture, and the evenness was successfully analysed. In conclusion, the BMT could be a valuable tool to assess the cycle path surface condition in relation to bicycle riding comfort. (Less)
- Abstract (Swedish)
- Cyklisters åkkomfort, kopplat till cykelvägens textur och jämnhet, har hittills inte undersökts på ett uttömmande vis. Det beror delvis på att det saknas tillståndsbedömningsmetoder som är speciellt utvecklade för cykelvägarnas lägre hastighetsgränser och begränsade utrymme. Det behövs textur- och jämnhetsmått som passar cyklisters, och inte bilisters, upplevda åkkomfort. I den här artikeln presenteras och utvärderas en ny mätmetod, Cykelmätvagnen, som bidrar till en mer lämplig tillståndsbedömning av cykelvägsytor. Åtta olika typer av cykelvägsytor utvärderades med avseende på textur- och för fyra av dessa utvärderades även den längsgående jämnheten. Tillförlitligheten i resultaten av mätningarna utvärderades, och fem olika mått... (More)
- Cyklisters åkkomfort, kopplat till cykelvägens textur och jämnhet, har hittills inte undersökts på ett uttömmande vis. Det beror delvis på att det saknas tillståndsbedömningsmetoder som är speciellt utvecklade för cykelvägarnas lägre hastighetsgränser och begränsade utrymme.

I den här artikeln presenteras och utvärderas en ny mätmetod, Cykelmätvagnen, som bidrar till en mer lämplig tillståndsbedömning av cykelvägsytor. Åtta olika typer av cykelvägsytor utvärderades med avseende på textur- och för fyra av dessa utvärderades även den längsgående jämnheten. Tillförlitligheten i resultaten av mätningarna utvärderades, och fem olika mått (Dynamiskt komfortindex, Jämnhetskoefficienten, 0,5 m rätskena, IRI och RMS) beräknades från inmätta data och resultaten analyserades. Resultaten indikerar att Cykelmätvagnen ger tillräcklig noggrannhet i mätningarna och att repeterbarheten är hög för normala cykelhastigheter. Ytorna kunde rankas med avseende på textur och jämnhet. Slutsatsen är att Cykelmätvagnen är ett lämpligt verktyg för att bedöma cykelvägars yttillstånd kopplat till cyklisters åkkomfort. (Less)
