Abstract
The aim of this study is to evaluate the bicycle compatibility of narrow back streets, which can be alternative routes for arterial roads like bypassed old type high streets. Bicycle users' sense and physical conditions, on cycling such as speed, vibration, conflicts with other road users, and air quality were compared between back streets, narrow streets, carriageway, and sidewalks. Back streets have better reputation than sidewalks shared with pedestrians, but have problems on the safety at junctions and conflicts with vehicles when it is narrow.
