- "Bicycle Research: Cargo Bikes and Bike-Truck Interactions"
Cargo e-bikes are two-, three-, or four-wheeled vehicles with cargo-carrying capacity. Since they are human-powered and often have an electric pedal assist, they are an alternative mode of delivering goods in dense urban areas. They present several advantages over the traditional modes of urban freight: they are more agile in navigating traffic, they occupy less space, and can potentially park anywhere. However, previous studies and pilots showed mixed results. The Urban Freight Lab has been collecting and analyzing data from cargo bike pilot studies and simulations to address questions on their operational efficiency, sustainability, and safety. Bike-truck conflicts are interactions between a bicyclist and another road user such that at least one of the parties must change direction or speed to avoid collisions.

Summary:
There is little research on the behavioral interaction between bicycle lanes and commercial vehicle loading zones (CVLZ) in the United States. These interactions are important to understand, to preempt increasing conflicts between truckers and bicyclists. In this study, a bicycling simulator experiment examined bicycle and truck interactions. The experiment was successfully completed by 48 participants.

Summary:
Urban freight deliveries are increasingly challenged in dense urban areas, particularly where delivery trucks are required to meet delivery time windows. Depending on the route characteristics, Electric Assist (EA) cargo bikes may serve as an economic and environmentally sustainable alternative to delivery trucks. In this paper, the cost trade-offs between a box delivery truck and an EA cargo bikes are compared.

Summary:
The Seattle Department of Transportation (SDOT) partnered with the University of Washington to explore how commercial vehicle parking in Seattle’s downtown area affects the safety of bicyclists. The hypothesis was that increased truck access to SDOT’s commercial vehicle loading zones (CVLZs) can positively contribute to bicycle safety.

Summary:
Introduction Completing urban freight deliveries is increasingly a challenge in congested urban areas, particularly when delivery trucks are required to meet time windows. Depending on the route characteristics, Electric Assist (EA) cargo bicycles may serve as an economically viable alternative to delivery trucks.

Summary:
This research report investigates the relationship between pedestrians and bicyclists on paths parallel to railroad tracks and with a road perpendicular to the path. The possible conflicts at intersections within these design parameters are of concern to ODOT, and therefore, has been recognized as an opportunity to conduct research that improves this type of intersection.
