Calibration of Smartphone Sensors to Evaluate the Ride Quality of Paved and Unpaved Roads
(2020)Transportation agencies report that millions of crashes are caused by poor road conditions every year, which makes the localization of roadway anomalies extremely important. Common methods of road condition evaluation ... -
Campus Parking Supply Impacts on Transportation Mode-Choice
(2014)Parking demand is a significant land-use problem in campus planning. The parking policies of universities and large corporations with facilities located in small urban areas shape the character of their campuses. These ... -
Characterizing Pavement Roughness at Non-Uniform Speeds Using Connected Vehicles
(2017)Methods of pavement roughness characterizations using connected vehicles are poised to scale beyond the frequency, span, and affordability of existing methods that require specially instrumented vehicles and skilled ... -
Characterizing Ride Quality With a Composite Roughness Index
(2022)There are many important applications that require ride quality characterization. However, the only international standard that specifies a roughness index is not suitable for applications beyond assessing the ride quality ... -
Closed Form Models to Assess Railroad Technology Investments
(2020)Class I railroads in North America collectively invested $11.2 billion to comply with a federal mandate to deploy positive train control. This amount dwarfs the potential savings from accidents the technology could prevent. ... -
A Cognitive Framework to Plan for the Future of Transportation
(2020)Automated, connected, electrified, and shared mobility will be cornerstones of the transportation future. Research to quantify the potential benefits and drawbacks of practice, and to identify barriers to adoption is the ... -
A Connected Vehicle Approach for Pavement Roughness Evaluation
(2014)Connected vehicles present an opportunity to monitor pavement condition continuously by analyzing data from vehicle-integrated position sensors and accelerometers. The current practice of characterizing and reporting ... -
Context Sensitive Solution: A Case Study of Northwest Highway White Rock Lake, Dallas in Texas
(2015)Loop 12 is the first ring around the city of Dallas. The project is a three-quarter mile section of Loop 12 on Northwest Highway. The project section of Northwest Highway is a set of six bridges that cross a 100-year ... -
Data-Driven Deployment of Cargo Drones: A U.S. Case Study Identifying Key Markets and Routes
(2023)Electric and autonomous aircraft (EAA) are set to disrupt current cargo-shipping models. To maximize the benefits of this technology, investors and logistics managers need information on target commodities, service ... -
Detecting Sources of Ride Roughness by Ensemble Connected Vehicle Signals
(2022)It is expensive and impractical to scale existing methods of road condition monitoring for more frequent and network-wide coverage. Consequently, defects that increase ride roughness or can cause accidents will go undetected. ... -
Effects of smartphone sensor variability in road roughness evaluation
(2021)Accelerometers embedded in smartphones have become an alternative means of measuring the roughness of roads. However, the differences in their sensitivity and sampling rates between smartphones could produce measurement ... -
Enabling Mobile Commerce through Pervasive Communications with Ubiquitous RF Tags
(2003)For many years we’ve heard of the existence of a wonderful new technology called radio frequency identification (RFID) that allows supermarket items to be checked out without human intervention. Advertisements claim ... -
Energy Efficiency of CSMA Protocols for Wireless Packet Switched Networks
(2004)The finite battery power in wireless portable computing devices is a motivating factor for developing energy efficient wireless network technologies. This paper investigates energy efficiency, relating it to throughput and ... -
Enhancement of Signals from Connected Vehicles to Detect Roadway and Railway Anomalies
(2019)Frequent network-wide monitoring of the condition of roadways and railways prevent fatalities, injuries, and financial losses. Even so, agencies cannot afford to inspect vast transportation networks using present methods. ... -
Error Sensitivity of the Connected Vehicle Approach to Pavement Performance Evaluations
(2016)The international roughness index is the prevalent indicator used to assess and forecast road maintenance needs. The fixed parameters of its simulation model provide the advantage of requiring relatively few traversals ... -
Exploratory Spatial Data Analysis of Traffic Forecasting: A Case Study
(2022)Transportation planning has historically relied on statistical models to analyze travel patterns across space and time. Recently, an urgency has developed in the United States to address outdated policies and approaches ... -
Extending Micromobility Deployments: A Concept and Local Case Study
(Springer, 2021)Micromobility is a recent phenomenon that refers to the use of small human- or electric-powered vehicles such as scooters and bikes to travel short distances, and sometimes to connect with other modes of transportation ... -
Forecasting the Effects of Autonomous Vehicles on Land Use
(2020)The widespread availability of connected and autonomous vehicles (CAVs) will likely affect social change in terms of how people travel. Traditional methods of travel demand and land use modeling require vast amounts of ... -
