A recently published study from Montreal sheds new light on the importance of the built environment in influencing bicycle commuting and the resulting impacts on greenhouse gas emissions. The researchers also estimated the effect of bicycle infrastructure accessibility on cycling mode share. They estimated the effect of the new bicycle infrastructure as yielding a 1.7 percent reduction in transportation GHG emissions, roughly equivalent to the estimated effects of replacing the city’s buses with hybrid models and electrifying the city’s commuter trains.
Car sharing is maturing, expanding options beyond the initial model of a station-based system structured around accessing and returning cars parked at designated location. Of particular interest is the free-floating car share model, or FFCS, which allows members to pick up and drop off a car anywhere within the service area without being tied to a designated parking location. This new choice, in use in Montreal, expands service flexibility geographically, but also broadens the member demographic, which could have additional environmental and congestion mitigation benefits.
