Car crashes are still a leading cause of death in the United States, with vulnerable road users like bicyclists and pedestrians being injured or killed at rates that outpace their mode share.
Planners, engineers, and advocates are increasingly adopting Vision Zero and Tactical Urbanism approaches and trying to better understand the underlying causes...

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods that address protected bike lanes (aka “cycle tracks” or “separated bike lanes”), only conventional striped bike lanes, shoulders, and shared streets. There are other methods for predicting comfort from a bicyclist’s perspective that do consider protected bike lanes, but they are either based only on expert opinion or on surveys in Denmark.
This presentation will describe how to evaluate the level-of-service of a protected bike lane using results from surveys conducted in the United States. The model developed by this project could be used to supplement the current HCM to objectively consider a wider...

Abstract: The New Energy Vehicles (NEVs) industry has become one of the national strategically rising industries in China under the pressure of energy safety and environment protection. In order to promote the use of new energy vehicles, China is now launching a big campaign, called "New Energy Vehicle 'Ten Cities & Thousand Units Demonstration' Plan". This presentation will be focused on the background, progress and some key issues to be addressed during the implementation of the demonstration plan. Specific cases of Shanghai, including the Expo demonstration and Chongming Island demonstration will also be mentioned.

Transportation and Road Weather
Where: Room 204 of the Distance Learning Center Wing of the Urban Center at PSU
Speaker: Rhonda Young, University of Wyoming
Topic: Transportation and Road Weather
Summary: Weather has a tremendous impact on the transportation system and is one of the largest contributors to non-recurring delay and increased crashes. Road weather is the a multidisciplinary area involving transportation engineers and meteorologists who are working to mitigate the negative effects of weather on the operation and maintenance practices of transportation systems. The talk covers the broad types of issues being studied in this field and looks at ways in which technology is playing a large part in the proposed solutions. The issue of weather as a complicating factor in the use of connected and autonomous vehicle technologies is also discussed.
