Summary:

This paper discusses how to promote high-speed rail (HSR) freight business by solving the congestion problem. First, we define the existing operation modes in China and propose the idea of relieving congestion by reserving more carriages of HSR passenger trains for freight between cities with large potential volume or small capacity. Second, we take one HSR corridor as a case to study, and use predictive regression and integrated time series methods to forecast the growth of HSR freight volume along the corridor. Finally, combined with forecast results and available capacity during the peak month of 2018, we offer suggestions on the mode adoption in each segment during the peak month from 2019 to 2022. Results demonstrate: (1) Among all 84 Origin-Destination (OD) city flows, the percentage of those monthly volumes over 1 ton increases from 17.9% in 2018 to 84.6% in 2022, and those over 30 tons rise from 3.6% to 26.2%. (2) Among the segments between seven main cities in the HSR corridor, T-J should be given priority to operate trains with reserved mode; the segment between X and J deserves to reserve most carriages during the peak month in the future. Specifically, our model suggests reserving 5.3–10.1 carriages/day for J-X, and 4.8–16.3 carriages/day for X-J during the peak month from 2019 to 2022.

Shipping Resilience: Strategic Planning for Coastal Community Resilience to Marine Transportation Risk (SIREN)

Many coastal communities across Canada are highly dependent upon maritime transportation systems that are vulnerable in natural disasters. This project aims to improve understanding of how coastal maritime transportation systems would be disrupted in natural hazard events, how such disruption would impact coastal communities, and what strategies could effectively address this risk.

Ports across Canada are vulnerable in natural disasters, and their disruption can pose severe consequences for marine transportation systems and the coastal communities that rely on them. This project aims to improve understanding of how different types of ports may be affected in hazard events, with focus on catastrophic earthquake risk in coastal British Columbia, and consideration of severe hurricane damage to ports in Eastern Canada.

Focusing on the movement of people and goods in the emergency response phase of a disaster, the research team develops new tools, information, and risk assessments to support preparedness planning by local and provincial governments and the transportation sector. Through iterative engagement with stakeholders, the research is also intended to foster dialogue and shared understandings of risk that are necessary for resilience planning.

The research consists of an interrelated set of activities:

  • Organization of workshops for engaging government and transport sector stakeholders.
  • Development of a framework for assessing community resilience to shipping and port disruption.
  • Development of a model and simulation tool for the coastal maritime transportation system and regional multimodal logistics system.
  • Development of a simulation model for port operations and vulnerabilities to natural hazards.
  • Development of an approach for evaluating the effectiveness of the modelling approach.

Research questions:

  1. How would a major disaster likely affect marine transportation routes?
  2. How would this marine transportation disruption affect the movement of people and resources in the emergency response phase?
  3. What strategies (e.g., alternate routes and/or transport modes) would be effective for different types of communities in alleviating the potential consequences?
  4. Will a port be available, and in what state, after a natural hazard event, considering its own vulnerability and the vulnerability of interdependent infrastructure (e.g., road access, electric power)?
  5. Based on expected states, what ports could be used for ingress and egress of populations and resources during the immediate and sustained response phases of a catastrophic disaster?
  6. What strategies would be effective for different types of ports to reduce failure risk or improve functional resilience?

Ridehail and Commercial Vehicles Access in Urban Areas: Implications for Public Infrastructure Management

Summary:

As urbanized populations and concentrations of activities increase, there is growing pressure in dense and constrained urban areas to unlock the potential of every public infrastructure element to address the increasing demand for public space. Specifically, there is a growing demand for space for parking operations related to the access to land use by people and goods. On one side, ridehailing services, such as those provided by Uber and Lyft, are on the rise and with them the associated passenger pick-up/drop-off (PUDOs) operations. On the other side, freight and servicing trips require a supply of adequate infrastructure to support vehicle access and load/unload activities and final delivery/service to customers. This dissertation aims to provide insights based on real-world datasets and tests to support the management of two key public infrastructure that provides access to land uses: alleys and curb lanes. To achieve this goal, first, this dissertation will investigate what roles alleys play in cities and inspect alleys’ physical characteristics and vehicle parking operations in these spaces. Secondly, this research will examine factors of PUDO dwell time and evaluate the impact of adding curb lane PUDO zones and geofencing ridehailing vehicles to these zones using a hazard-based duration modeling approach. Finally, this dissertation will analyze the impact of different ridehailing curb management strategies on curb lane utilization based on simulation.

Urban Goods Delivery Toolkit

URL: https://depts.washington.edu/toolkit/
Publication Date: 2020
Summary:

This Toolkit is designed to help transportation professionals and researchers gather key data needed to make the Final 50 Feet segment function as efficiently as possible, reducing both the time trucks park in load/unload spaces and the number of failed first delivery attempts.

In addition, the toolkit can help transportation planners, traffic engineers, freight system managers, parking and operations strategists, and researchers build a fundamental knowledge base for planning; managing parking operations; managing emergency management and response; updating traffic, land use and building codes; and modeling future scenarios and needs.

In short, the toolkit can be used to help cities meet the ever-increasing demand for trucks and other load/unload activities.
