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...

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors
Miguel Andres Figliozzi
Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In parti...
