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.
Urban transportation infrastructure includes facilities such as loading docks and curb space which are important for freight pick-up and delivery operations. Information about the location and nature of these facilities is typically not documented for public or private urban freight stakeholders and therefore cannot be used to support more effective private sector operations or public sector planning and engineering decisions.
This paper presents a framework to classify and mitigate roadway bottlenecks and that is designed to improve freight mobility. This is in recognition that roadway operations for trucks are under studied, truck-only bottlenecks are often not identified and freight-specific problem areas are therefore often overlooked. The framework uses four-steps. Step 1 identifies and locates the roadway sections where vehicle travel time is in excess of what would normally occur.
An inadequate supply of parking spaces for long-haul drivers creates safety issues that may lead to severe or fatal crashes, as tired drivers face the decision of choosing between parking at unsafe locations or continuing to drive.
To better understand the current use of truck parking facilities and safety issues caused by the lack of parking capacity in high-demand locations, the authors reviewed existing research and reports that describe the lack of parking in the PacTrans region. The researchers then identified and provided a qualitative analysis of future trends that will affect this problem.
Finally, the research team developed and executed a survey of truck drivers at two long-haul trucking parking facilities. The research team focused on two high-volume multi-state truck corridors, the Interstate 5 and 90 corridors, that are of interest to the Washington State Department of Transportation (WSDOT) and neighboring state DOTs. This study presents the data collection method, the overall survey results, and an analysis of the findings.
This research provides original data as well as expert insights to support state decision-making in determining the beneficiaries of building and maintaining public and private truck parking rest stops in Washington state.
This paper evaluates whether or not there is a sprawling tendency to the spatial patterns of warehouse establishments in the Chicago and Phoenix metropolitan areas. The trend of warehouses to move away from the urban centers to more suburban and exurban areas is referred to as “Logistics Sprawl”.
Two converging trends – the rise of e‐commerce and urban population growth – challenge cities facing competing uses for road, curb and alley space. The University of Washington has formed a living Urban Freight Lab to solve city logistics problems that cross private and public sector boundaries.
Goods delivery is an essential but little-noticed activity in urban areas. For the last 40 years, deliveries have been mostly performed by a private sector shipping industry that operates within general city traffic conditions.
This research paper estimates carbon dioxide (CO2) emissions and vehicle-miles traveled (VMT) levels of two delivery models, one by trucks and the other by unmanned aerial vehicles (UAVs), or “drones.” Using several ArcGIS tools and emission standards within a framework of logistical and operational assumptions, it has been found that emission results vary greatly and are highly dependent on the energy requirements of the drone, as well as the distance it must travel and the number of recipie
There are more than 212,000 at-grade railroad crossings in the United States. Several feature paths running adjacent to the railroad tracks, and crossing a highway; they serve urban areas, recreational activities, light rail station access, and a variety of other purposes. Some of these crossings see a disproportionate number of violations and conflicts between rail, vehicles, and pedestrians and bikes.
