Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual counting methods, however over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Due to cost and other resource considerations, permanent counts are still limited to small subsets of networks...

How Can E-bike Purchase Incentives Grow the E-bike Market?
John MacArthur
Christopher Cherry , Luke Jones
The electric bicycle (e-bike) is a low-emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security, among others. Despite the establishment of a stable and growing market, e-bike ownership remains prohibitively expensive for many people. Across the world, incentive programs have emerged as a popular technique in the effort to bridge the chasm of e-bikes' technology...
