Economic Implications of the Use of Technology in Commercial Vehicle Operations

Publication Date: 2012
Summary:

The effective and efficient movement of freight is essential to the economic well-being of our country but freight transport also adversely impacts our society by contributing to a large number of crashes, including those resulting in injuries and fatalities. Technology has been used increasingly to facilitate safety and operational improvements within commercial vehicle operations, but motor carriers operate on small profit margins, limiting their ability to make large investments without also seeing an economic benefit from such technologies. This dissertation explores the economic implications associated with using onboard monitoring systems to enhance safety in commercial vehicle operations.

First, to better understand how electronic on-board systems work, paper-based methods of recording driver hours of service are compared to automated (or electronically recorded) hours of service for three motor carriers using process analysis. This analysis addressed the differences between manual (paper-based) and electronic methods of recording hours of service, specifically as they relate to the frequencies and magnitude of the errors. Potential errors are categorized by operations within an information-based process and the findings suggest that a reduction of errors can be achieved with an electronic system.

A benefit-cost analysis provides a better understanding of the economic implications of onboard monitoring systems from the perspective of the carrier. In addition to the benefits of reduced crashes, benefits associated with electronic recording of hours of service, reduced mileage, and reduced fuel costs are considered. A sensitivity analysis is used and demonstrates that on-board monitoring systems are economically viable under a wide range of conditions. Results indicate that, for some fleet types, reducing crashes and improving hours of service recording, provides a net benefit of close to $300,000 over the five-year expected lifespan of the system. Furthermore, when exploring additional benefits such as reduced fuel consumption and reduced vehicle miles, benefits can be upwards of seven times more than safety-related benefits. This research also shows that net positive benefits are possible in large and small-sized fleets. Results can be used to inform policies for motivating or mandating carriers to use such systems and to inform carriers regarding the value of system investment.

Pages: 88-94

Summary:

The outer coast of Washington State is exposed to significant seismic and tsunami hazards. A Cascadia Subduction Zone (CSZ) event is expected to cause high earthquake intensities and tsunami inundation resulting in considerable infrastructure loss, inundation of developed land, and degraded functioning of coastal communities.

One area of particular concern is Pacific County, located in southwest Washington, where over 85% of the population is expected to experience severe shaking intensities.

This paper establishes the pre-disaster passenger and freight transportation patterns and the damaged post-disaster road network in Pacific County. The hazard used in the analysis is the CSZ magnitude 9.1 earthquake and resulting tsunami. Passenger travel is compared to forestry travel along the following characteristics: overall change in travel distance, percentage of trips that are longer, the percentage of trips that are no longer possible, and the distributions of travel distance.

Because passenger and freight travel have different purposes and patterns, understanding how they are affected differently can serve as a foundation for community-based disaster recovery planning to increase community resilience to earthquakes and tsunamis.

Assessing the Safety Effects of Cooperative Intelligent Transport Systems: A Bowtie Analysis Approach

Publication: Accident Analysis and Prevention
Volume: 99 (A)
Pages: 125-141
Publication Date: 2017
Summary:

The safety effects of cooperative intelligent transport systems (C-ITS) are mostly unknown and associated with uncertainties, because these systems represent emerging technology. This study proposes a bowtie analysis as a conceptual framework for evaluating the safety effect of cooperative intelligent transport systems. These seek to prevent road traffic accidents or mitigate their consequences. Under the assumption of the potential occurrence of a particular single-vehicle accident, three case studies demonstrate the application of the bowtie analysis approach in road traffic safety. The approach utilizes exemplary expert estimates and knowledge from literature on the probability of the occurrence of accident risk factors and of the success of safety measures. Fuzzy set theory is applied to handle uncertainty in expert knowledge. Based on this approach, a useful tool is developed to estimate the effects of safety-related cooperative intelligent transport systems in terms of the expected change in accident occurrence and consequence probability.

  • Freight Mobility in Urban Areas
  • Transportation Technology Evaluation
  • Freight Systems Performance Measurement

Dr. Ed McCormack’s research program is broadly around the theme of the use of technology to improve mobility for people and goods. Improved data storage, wireless communications, and faster computers have created new streams of high quality transportation information. This information allows operators and the public to be more strategic and efficient about using our transportation system but also requires new thinking and innovative approaches. Given the belief in our society that technology can solve many problems, one challenge that he frequently addresses in his research is elemental: what works? For example, his research has evaluated the application and usability of different in-vehicle tracking technologies and of freight-oriented traveler information systems.

A second topic of importance is his recent research—derived from his interest in technology—that explores the development of quantitative tools that can use streaming data. Many of his projects have used these data to create performance measures that allow the monitoring of vehicle travel activity and the calculation of metrics that support engineering and planning decisions.

He has increasingly focused on freight mobility. Despite freight’s obvious importance to our society, this area of transportation has traditionally been understudied by academics, particularly in comparison to people transportation. As a researcher, he has found that there are opportunities to provide innovative insights in this area.

Paper

Exploring Transportation Applications of Small Unmanned Aircraft

Publication: Institute of Transportation Engineers (ITE) Journal
Volume: 79 (12)
Pages: 32-36
Publication Date: 2009
Summary:

This article describes the promise of small unmanned aerial vehicles (UAVs) in transportation-related applications. Small UAVs are increasingly affordable, easy to transport and launch, and can be equipped with cameras that provide information usable for transportation agencies. Potential uses of UAVs include accident scene photography, surveying, security inspections, construction data collection, and monitoring the condition and congestion of roadways. However, there are currently limitations that hinder the use of UAVs by state departments of transportation. The limitations are linked to the need to obtain authorization from the Federal Aviation Administration, which has expressed concern about the ability of UAVs to see and avoid manned aircraft. Recent tests were conducted by the Washington State Department of Transportation to evaluate the technical capabilities and institutional concerns related to the use of UAVs. Results from these tests indicate that the UAVs can perform effective and autonomous aerial surveillance, but concerns linger about the reliability of UAVs and the consequences of a crash.

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

A catastrophic earthquake could disrupt marine transportation across coastal British Columbia, severely affecting supply chains to coastal communities and emergency response capabilities. This project seeks to better understand such risks and develop effective resilience strategies for different types of coastal communities. It inquires into how disaster events would likely affect ports, marine transportation routes, and the associated movement of people and resources in the emergency response phase, and what strategies would be effective to alleviate potential consequences.

Co-principal investigators on this project are David Bristow at the University of Victoria (infrastructure systems modeling), Ron Pelot and Floris Goerlandt at Dalhousie University (shipping risk), C. Lin and L. Zhou at the University of Victoria (port geotech and structural modeling), and Anne Goodchild at the University of Washington (shipping logistics).

This project aims to improve understanding of how coastal marine transportation systems would be disrupted in natural hazard events, how such disruption would impact coastal communities, and what strategies could effectively address this risk. Focusing on the movement of people and goods in the emergency response phase of a disaster, the study develops new tools, information, and risk assessments to support preparedness planning by local and provincial governments and the transportation sector. The research delivers: (1) workshops for engaging government and transport sector stakeholders; (2) a framework for assessing coastal community resilience to shipping disruption; (3) a simulation tool based on this framework; and (4) specific findings and recommendations for two case studies – a detailed analysis of catastrophic earthquake risk in British Columbia and exploratory analysis of hurricane risk in Atlantic Canada.

Summary:

Freight transport is a challenging economic sector, as it is essential for the functioning of production and distribution systems but and the same time is at the origin of many nuisances such as congestion, greenhouse gas emissions, pollution and noise. When responding to these issues, planners dispose nowadays of a growing body of freight data that can be used for the implementation of policies towards achieving smart mobility. Because contrary to current practice and dominant discourse, smart mobility is not just a matter of passengers: it also largely relies on more sustainable freight plays an transport. Policy makers see in those new sources of data an opportunity to increase their knowledge on freight transport as well as to have suitable decision support tools to the choices they need to make. In developed countries this trend is illustrated by the increasing requirement of data by recent legislation on freight transport. But these data are not always easily available, and when they are, they are not necessarily adapted to the needs of practitioners. This mismatch partly results in a lack of dialogue between researchers and practitioners, that this special issue intends to promote.

Behavior-Based National Freight Demand Modeling

Current models for forecasting freight movement in the United States have been developed primarily at the statewide level, along with a few regional freight forecasting models. This project is developing a national freight forecasting model for the FHWA. The model, the first of its kind at the national level, will support national freight policy making and planning. As a subcontractor to RSG, UW researchers are helping to identify the most useful and promising structures for a national model and are leading the evaluation of model components and their integration. They are also developing an approach to test the potential specifications for each model component and are contributing to the development of national sources of data for use in the model. The project will demonstrate the model in a software application.

Publication: Transportation Research Record: Journal of the Transportation Research Board
Volume: 2097
Pages: 19-25
Publication Date: 2009
Summary:

This paper summarizes a broad literature review on system resilience. After these interpretations of resilience are considered, a definition of resilience in the context of freight transportation systems is provided. The definition of resilience offered here captures the interactions between managing organizations—namely, state departments of transportation, the infrastructure, and users—which is critical considering that the freight transportation system exists to support economic activity and production. A list of properties of freight transportation system resilience is outlined. These properties of resilience can contribute to the overall ability of the freight transportation system to recover from disruptions, whether exhibited at the infrastructure, managing organization, or user dimension. This contribution provides a framework that can serve as a starting point for future research, offering a shared language that promotes a more structured conversation about freight transportation resilience.

Summary:

As of June 2020, the novel coronavirus disease (COVID-19) has infected more than eight million people worldwide. In response to the global pandemic, cities have been put under lockdown, closing non-essential businesses and banning group gatherings, limiting urban mobility, and issuing stay-at-home orders, while nations closed their borders.

During these times, logistics became more important than ever in guaranteeing the uninterrupted flow of goods to city residents. At the same time, the same supply chain providing the goods experienced profound disruptions. Documenting the impacts the COVID-19 outbreak had on individual organizations and their responses is an important research effort to better understand the resiliency of the supply chain.

The Urban Freight Lab, a structured workgroup of senior executives from major supply chains, supply chain related companies, and academic researchers from the University of Washington, carried out a survey to address two main questions:

  • What are the most common and significant impacts of the COVID-19 outbreak?
  • What short-term actions and long-terms plans are supply chains taking in response to the pandemic?
