The residential streets in most of a city’s road system are usually amenable to bike riding, but when these residential streets meet main arterials, the streets are often less friendly to biking. This may mean that fewer people are likely to consider a bike as a viable transportation option for going across town. A recent study described in theatlanticcities.com found that a modest investment could dramatically improve the connectivity of a city’s bike network. Suggested improvements include traffic-calming measures and intersection safety measures including median refuge islands, bike lanes and separated cycle tracks.
