Topic: Identifying Transit Deserts in Eight US Cities: Where the Supplies Missed the Demands

[Abstract] The term "transit desert" is a new concept that looks at the gap between level of transit service (supply) and needs of a particular population (demand). These populations are often referred to as "transit dependent," people that are too young, too old, or too poor or who are physically unable to drive. "Transit deserts" in this case are defined as areas that lack adequate public transit service given areas containing populations that are deemed transit-dependent. This study aims to analyze and establish a clear method for calculating and quantifying gaps between transit demand and supply using Geographic Information Systems (GIS). The study looks at eight major US cities: Charlotte, NC; Chicago, IL; Cincinnati, OH; Portland, OR; Austin, TX; Dallas, TX; Houston, TX; and San Antonio, TX. Transit deserts often occur in neighborhoods surrounding historic downtowns; however, exceptions occur in very isolated rural areas.

Topic: Development of a Security Platform for Vehicle to Infrastructure Network

[Abstract] Ensuring that the connected transportation ecosystem is cognizant of potential cyber-attacks is extremely important. Specifically, ensuring the secure communication between diverse stakeholders in connected transportation systems is perhaps the major challenge to the safe and reliable system operations. The primary security risks may originate in different interface levels in connected transportation systems, such as Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I) or Infrastructure to Infrastructure (I2I). However, today's Information Technology (IT) security ecosystem, which relies on a combination of static perimeter network defenses (e.g., firewalls and intrusion detection/prevention systems), ubiquitous use of end-host based defenses (e.g., antivirus), and software patches from vendors (e.g., Patch Tuesday), is fundamentally ill equipped to handle the security issues in the connected vehicle ecosystem. In this presentation, a flexible and reliable security protection platform will be discussed. This platform leverages emerging network techniques that support the development of Vehicle to Infrastructure security solutions.

Topic: Mode Choice Behavior and Motorization of E-bike Users in China

[Abstract] China has seen unprecedented increases in motorization in the past decade, and will continue to see growth in vehicle ownership and use. While economic growth and the rising middle class influence this motorization trend, there are several factors that make this new motorization trend stand out from historical increases in motorization in the West.

This study examines household vehicle purchase decision concerned with regular vehicles and electric vehicles by two surveys conducted in 2013 and 2015 in China. The first survey explores vehicle purchase decision with broad geographic, environmental, and socio-economic characteristics focusing on a subset of households who own e-bikes and rely on a telephone survey from an industry customer database. From these responses, we estimate two three-level hierarchical choice models to assess attributes that contribute to 1) recent car purchases and 2) the intention to buy a car in the near future. The second survey aims at understanding new transportation mode's impact on adoption of vehicle purchase and symbolic meanings of electric vehicles in China. This study will assist policy makers in developing appropriate regulations or incentives that encourage judicious purchase and use of vehicles of various types, and suggest potential region-specific policy approaches to managing car purchase may be necessary.

Topic: Using simulation or the HCM to assess LOS in highway facilities: The case of 2-lane highways and 2+1 highways

[Abstract] The seminar will start with a brief introduction of the Escuela de Ingenieros de Caminos at Universidad Politecnica de Madrid (UPM), and its exchange program. In some consulting circles, in recent times, microsimulation has been embraced as the main tool to analyze how transportation, and in particular, highway facilities run, what are their capacities and to what Level of service (LOS) are they operating. In this regard, tools like the HCM are being overlooked as obsolete, or primitive. Is this correct? Has microsimulation completed the run to displace all other tools? Mostly, the validation and calibration efforts have to be taken into account when budgeting the study, and quality of the final model has to be discussed. In the seminar we will introduce the subject and consider two examples: 2-lane highways and 2+1 highways. We will introduce this new (for most of the US) kind of highway, and discuss MOEs to assess the quality of any simulation. The available macro models, research results and microsimulation results will be compared. We will also mention the upcoming version of HCM (6th Edition). Finally, comments on the role of Civil Engineers in the next generation of transportation studies will be discussed, in a time when digital infrastructure is starting to play a major role in transportation studies and facility management.

Topic: New Advances in Cooperative Games Based Highway Cost Allocation

[Abstract] The objective of Highway Cost Allocation (HCA) is to divide fairly and rationally construction, rehabilitation, maintenance, and operation costs of highways and bridges among vehicle classes using them. This presentation highlights a new HCA approach that recognizes variable capacity and pavement thickness requirements among vehicle classes. Considering vehicle classes as players and groups of vehicle classes as coalitions, a characteristic function of the game is proposed to estimate the cost for each coalition considering lane and traffic loading requirements. The cost of the grand coalition (including all players) is allocated by a linear programming formulation with constraints representing three requirements of a game-theory model known as the least core: completeness, marginality and rationality. If the optimal basic solution is unique, it is known as the nucleolus. Otherwise, the nucleolus is the average of all multiple solutions. A primal-dual tie breaking procedure is used to determine the nucleolus without identifying the multiple solutions.

[Speakers' Bio] Saurav Kumar Dubey is pursuing his PhD in the Department of Industrial and Systems Engineering at the University of Tennessee, Knoxville. His research interests include strategic cost management, game theory, cost/benefit optimization, and transportation economics.

Topic: Traffic Signal Control Systems Transforming to Connected and Driverless Vehicles

[Abstract] Hardware/software improvements to traffic signal control systems are proposed to provide cost-conscious solutions and technologies to supplement existing transportation systems and alleviate rural arterial congestion with built in safety features. The optimization models for better traffic flows have three layers.

The fundamental layer is the traffic propagation models, which take traditional traffic data and connected vehicle data (with some penetration rate) in real time as input. The traffic then propagates from one intersection to another to provide near team forecast. In the middle layer, the splits of phases are adjusted to balance the predicted upcoming demands of approaches of all intersections based on the real time information above. In the outer layer, the models optimize offsets of all intersections simultaneously. Dynamic programming is utilized to solve the offset optimization. An advanced traffic simulator with connected vehicle communication/traffic signal hardware-in-the-loop simulation capacity, ETFOMM, was selected to program, debug, implement, and evaluate the performance of the models. Case studies with connected vehicles penetration rates of 10%, 25% and 50% on an arterial, at State Street in Jackson, MS, were conducted. The field signal timing plans were coordinated and optimized using TRANSYT-7F as the benchmark. The simulation results indicate the models significantly outperform TRANSYT-7F with about at least 50% control delay (second per vehicle) reduction, and with an increase of throughput (no less than 4.4%) in both directions of major and minor streets.

Topic: Incorporating Behavioral Effects from Vehicle Choice Models into Bottom-Up Energy Sector Models

[Abstract] Many types of models are used for evaluating climate-change-related programs and policies, ranging from "top down" models of the entire economy (e.g., computable general equilibrium, or CGE models) to specialized models focused exclusively on specific markets (e.g., Oak Ridge's MA3T model of the personal vehicle market). Somewhere in the middle are "bottom up" models of the energy sector (so-called E4, or "energy/economy/environment/engineering" models). A major concern is that E4 models, despite their high level of technological detail, yield unrealistic consumer market responses, calling into question their value for making policy decisions. We have developed a theory-based framework for modifying E4 models to produce more realistic market behavior, by incorporating behavioral factors from more detailed models like MA3T.

[Speakers' Bio] Professor Bunch is an internationally recognized expert on discrete choice modeling methods, which are used to understand and predict consumer choices when they select one product from a competing set. His research interests include new product development and introduction, travel behavior, and vehicle choice, including market potential for alternative fuel vehicles.

Topic: Energy Management, Eco-driving and Traffic Coordination Systems: Paths to Address Transportation Efficiency

[Abstract] Environmental concerns along with stronger governmental regulations regarding automotive fuel-economy and greenhouse-gas emissions are contributing to the push for development of more sustainable transportation technologies. Furthermore, the widespread use of the automobile gives rise to other issues such as traffic congestion and increasing traffic accidents. Consequently, two main goals of new technologies are the reduction of vehicle fuel consumption and emissions and the reduction of traffic congestion. While an extensive list of published work addresses the problem of fuel consumption reduction by optimizing the vehicle powertrain operations, particularly in the case of hybrid electric vehicles (HEV), approaches like eco-driving and traffic coordination have been studied more recently as alternative methods that can, in addition, deal with the problems of traffic congestion and traffic accidents. This talk will address the equivalent consumption minimization strategy and approaches to tune its equivalent coefficient to achieve more efficient operation of hybrid electric vehicles. It will also include an overview of research efforts to address transportation efficiency through the implementation of eco-driving and traffic coordination systems.

Topic: Efficient Algorithms for Networked Data Processing Challenges in Connected Vehicle Networks

[Abstract] With advances in vehicle-to-vehicle communication, future vehicles will have access to a communication channel through which messages can be sent and received when they get close to each other. This enabling technology makes it possible to view connected vehicles as a networked computational platform, where a range of algorithmic challenges arise for processing data efficiently. In this seminar, we consider a few challenges related to this platform, focusing on two key problems: first, how can we process distributed user queries efficiently within delay bounds? Second, how can we generate estimates on collected sensing data from vehicles with limited computational resources? We present approximate and probabilistic algorithms for both challenges, and provide insights on how to implement the algorithms in future vehicular testbeds.

Topic: Decentralized Optimal Control of Connected and Automated Vehicles

[Abstract] Recognition of the necessity for connecting vehicles to their surroundings is gaining momentum. In this "new world" of massive amounts of data from vehicles and infrastructure, what we used to model as uncertainty (noise or disturbance) becomes an extra state information in a much higher-dimensional vector. This talk will address the problem of coordinating vehicles that are wirelessly connected to each other at different transportation segments, e.g., intersections, merging roadways, to achieve a smooth traffic flow without stop-and-go driving. We present a closed-form solution that optimizes the acceleration profile of each vehicle in terms of fuel consumption while avoiding collision with other vehicles. The proposed solution is validated through simulation. The results show connectivity can significantly reduce fuel consumption and travel time.

Topic: On-Road and Test Cycle Fuel Economy: Is the Gap Growing?

[Abstract] US government fuel economy tests are used: 1) to monitor automobile manufacturers' compliance with fuel economy and greenhouse gas emissions standards and 2) to inform consumers about the fuel economy of passenger cars and light trucks. This study analyzes a unique database of 75,000 fuel economy estimates self-reported by customers of the US government website (www.fueleconomy.gov) to evaluate the effectiveness of the government's estimates for these two purposes.

The analysis shows great variability in individuals' own fuel economy estimates relative to the official government estimates, but much smaller bias relative to the sample average. The analysis also examines correlations between individuals' fuel economy estimates and specific technologies, vehicle class, driving style, method used to calculate fuel economy, manufacturer, and state. There is some evidence that the shortfall between test cycle fuel economy estimates and in-use fuel economy estimates has been increasing since 2005.

If this trend continues, it could affect the benefits realized by fuel economy and greenhouse gas emissions standards.

Topic: Driving Volatility in a Connected and Cooperative Vehicle Environment: Algorithms for Driver Warnings and Control Assists

[Abstract] Innovative connected vehicle solutions will address major societal problems of safety, mobility, energy, and air quality. A technical challenge in this regard is to enable drivers to take advantage of new and intelligent technologies and estimate how drivers will respond to such information, and how warnings and controls assistance can help improve performance.

Especially important in this context is driving volatility, characterized by hard accelerations/braking, jerky movements, sharp lane changes or turns, and abnormally high speeds for the operating conditions. Can these be mapped to a combination of local and global traffic states surrounding the vehicles? Are they related to how surrounding vehicles behave and are they related to socio-demographics of drivers?

These questions will be discussed in the context of connectivity between vehicles and civil infrastructure. Chakraborty will review several analytic procedures for understanding driving volatility, as well as the use of empirical data for generating valuable information and driver feedback. Specifically, he will discuss algorithmic means to formulate and evaluate parameters of a Markov Decision Process based model, which will be a step towards anticipating instantaneous driver maneuver decisions.

He will also present a framework for learning driver-specific estimates of rewards and penalties for available maneuver choices in a particular situation, using a Bayesian Inverse Reinforcement Learning framework. Gossip algorithms to incorporate the effect of social persuasions from other drivers in an autonomous and connected vehicle environment will also be discussed.

Topic: Real World Practical Influences on Vehicle Routing and Urban Delievery

[Abstract] Logistics activities at major corporations and supply chains around the world include the routing and delivery of products to hundreds of locations spread over large geo- graphical areas. To improve the efficiency and effectiveness of routing and delivery operations, transportation managers regularly utilize supply chain software packages to solve multiple versions of the vehicle routing problem. These solutions are implemented by transportation managers and dispatch managers of the vehicle fleets responsible for product delivery. However, the stability of traditional algorithms may not be consistent when faced by real world conditions including variations in spatial patterns of delivery locations and problems created by traffic, construction or other unexpected events. This is especially true in urban environments where last mile delivery has become a major is- sue for transportation companies across the nation. This presentation covers the results of research in vehicle routing under real world conditions, and also highlights an on-go- ing stream of research that focuses on strategies and analytical approaches for solving urban delivery and routing issues. Results from this research stream have implications for transportation managers and are expected to shed light on new challenges and future opportunities for transportation researchers and practitioners."

Topic: Tennessee's Highway Traffic Safety Culture - What We Think We Know


The presentation will be webcast and archived. The URL access is: Seminar Webinar

[Abstract] 14,850 individuals lost their lives in traffic crashes on Tennessee roadways from 2000 through 2013. The encouraging news is that both the number of annual fatalities and the fatality rate have declined substantially in the state since 2004. Unfortunately, almost 1,000 Tennesseans were killed in traffic crashes in 2013, thus the highway safety issues facing Tennessee are far from resolved. In 2011 the Tennessee Traffic Safety Culture Survey was initiated through a partnership between the UT Center for Transportation Research (CTR) and the Tennessee Governor's Highway Safety Office (GHSO). It measures attitudes and opinions about traffic safety issues and driving habits of Tennesseans. Since 2011, thousands of Tennesseans have participated in this annual survey. This seminar will present research findings from the survey program.

Topic: Designing Power Electronics to Meet the Demands of Future Electric Vehicles


[Abstract] In March 2012, President Obama announced the EV Everywhere Grand Challenge-to produce plug-in electric vehicles (PEVs) as an affordable and convenient form of transportation for the American family to replace gasoline-powered vehicles by 2022. Meeting these objectives will require significant advances in the electric-drive systems of PEVs, including 40% reduction in weight, 400% reduction in cost, and 40% reduction in power losses. At the heart of these systems are power electronic circuits, which control and convert between chemical, mechanical, and various forms of electrical energy. This talk will give an overview of the role of power electronics in the electric vehicle and their affects on transportation; it will present design tradeoffs and ongoing research at UTK that address the needs of future generations of electric vehicles.

Topic: The "Big Move:" Challenges in Transporting a Super Heavy and Over Sized Load


[Abstract] The Big Move was a project to transport the largest electric generator component of Dominion Power's Virginia City Hybrid Energy Center from Knoxville TN to St. Paul VA-a 176-mile, 19-day trip. An intricately specialized 28-dolly rig was chosen to handle the extreme weight and size of the stator. Weighing 1.4 million pounds, the rig with the stator was 265' long, 23' wide, and more than 17' tall; its top speed was 10 mph and it could not back up during the haul. The rig had more than 224 tires, and was powered by as many as six trucks with 600+ horsepower each. Several state police vehicles, utility bucket trucks, support trucks, and escort vehicles accompanied the rig. Key safety, risk management, and operational considerations included roadway geometrics, load/stress limitations on bridges and pavements, clearance envelopes, and traffic control along the route. The project required specialized route control documents and engineering support for innovative techniques for hauling across bridges, as well as intense stakeholder coordination, and a context sensitive approach to communicating with affected communities. The seminar will highlight challenges involved with this unusual and complex transportation situation, and present the innovative and successful strategies adopted to address them.

Topic: The Future of Transportation Finance


[Abstract] Motor fuel taxes at the state and federal levels have for nine decades provided a very large share of the revenue used by transportation agencies to build, maintain, and operate transportation systems. Falling fuel tax revenues have put transportation agencies into deep fiscal crisis because fuel taxes have not been increased in twenty years. Rising infrastructure costs and improved fuel efficiency of vehicles have reduced the real value of fuel taxes by more than half. This seminar will review the decline in these revenues and will look at several alternative mechanisms for funding transportation programs. Short- term and longer term solutions to this problem will be discussed. Especially highlighted will be local option sales taxes that are widely used by counties in California and longer term prospects for replacing motor fuel taxes by mileage based user fees which are advocated by many academics but which face a wide variety of challenges in the political arena.
