  4. 2. Winter maintenance and cycleways

    Author : Anna Bergström; KTH; []
    Keywords : cycleways; winter maintenance; maintenance service level; mode choice; winter cycling frequency; winter road condition assessment; bicycle measurements; friction measurement; winter maintenance equipment;

    Abstract : Increasing cycling as a means of personal travel couldgenerate environmental benefits if associated with acorresponding decrease in car-based transport. In seeking topromote cycling in wintertime, it is desirable to understandhow important the road surface condition is compared to otherfactors in people's decision to cycle or not. READ MORE
