Grade changes, wind, stop +signs, traffic signal timing, rough pavement, undulations, etc. all contribute +to the time and energy costs [Broach2012]_. Urban planners and civil engineers +design infrastructure and routes for bicyclists that have specific time and +energy costs associated with them. In fact, automobile routes and +infrastructure often have more preferable time and energy costs than the +parallel bicycle routes and infrastructure. These bicycle routes are quite +squiggly and are not optimizing the convenience of the bicyclists over the +automobile drive. Using simple physics-based simulations, existing and future +routes and infrastructure designs can be evaluated for time and energy costs. +This puts a clear quantitative numbers to important aspects of the convenience +of bicycling. + +Products +======== + +Theses + +- S.
