Available in PDF, EPUB and Kindle. Book excerpt: Congestion pricing and managed lanes (ML) have been recently gaining interest around the country as a congestion management tool and as a means of revenue generation for facility maintenance and expansion as well repayment of highway construction debts. Congestion pricing in MLs entails one of several strategies, including time of day pricing, dynamic pricing based on predicted/anticipated traffic conditions, and real-time dynamic pricing based on actual traffic conditions. The overall goal of this study has been to develop a Decision Support System (DSS) tool based on drivers' revealed willingness to pay (WTP) values. This should determine more effective dynamic toll pricing that achieves the ML corridors' operational goals. A key challenge has been estimating drivers' revealed WTP as influenced by their perceived values of time or by other factors such as enhanced safety and more reliable travel times. While there are significant advances made in the available methods to estimate WTP, research still lacks in the area of dynamic pricing. Indeed, for dynamic toll pricing systems, setting real-time toll prices based only on drivers' average WTP values appears ineffective. However, the WTP values estimated through existing methods represent the average value of travel time saving and/or reliability (VOT and/or VOR) for the total population. This makes the current approaches more compatible with static networks, which cannot efficiently address the nature of dynamic corridors. Another major drawback associated with current methods is that the travelers WTP values are measured in terms of price paid to save one unit of travel time (VOT). However, the travelers' WTP to use MLs has been shown to be for a number of intertwined reasons and not just for time savings. This study suggests a number of unique approaches in estimating WTP values. These include a new revealed data source as well as an alternative analysis method for estimating WTP. To obtain more accurate results, the study was limited to the North Tarrant Expressway (NTE) drivers in North Texas and was conducted for different time periods. For this study, traffic count data were reduced from the camera images for different vehicle categories and for five different time periods, including AM and PM peaks, AM and PM inter-peaks, and off-peak periods. In addition, real-time toll prices associated with the study segment and the day and time of the data collection were obtained from the NTE website. The data analysis method involved an existing toll pricing model (TPM) developed in a former Texas Department of Transportation study for setting tolls for MLs. The model was modified and calibrated based on actual ML shares and associated toll prices for the NTE ML corridor. The modified version of TPM (version 5.0) can be employed as a DSS tool to estimate the WTP values for drivers of any vehicle class and for any time of day. Values of about $119, $101, $71, $75, and $59 per hours were estimated as the revealed average WTP for the NTE SOV drivers during AM peak, PM peak, AM inter-peak, PM inter-peak, and off-peak periods, respectively. In addition, a value of $85 per hour was estimated for the mean revealed WTP (all periods inclusive) for the NTE SOV drivers. The results of this study showed relatively high WTP values and ML share percentages for the NTE drivers, indicating a high level of acceptance of MLs in the region. Finally, this study suggested applying a new paradigm in WTP estimation studies. The employed data collection and analysis methods were two components of the new paradigm. Besides, the new paradigm recommended evaluating real-time WTP by time of day instead of average WTP values for dynamic pricing schemes. The last component was a recommendation to attribute the WTP values to the travelers' willingness to pay to drive one unit distance on toll lanes instead of to save one unit of travel time.The DSS tool developed in this study for the NTE ML has the potential to be used by ML operators to measure the real-time WTP values for the ML users. The results of this new methodology may not directly address the questions about travelers' behavior in terms of their reasons to choose between the MLs and GPLs. However, these results can significantly contribute to decision making about transportation policies, in particular, the policies associated with dynamic congestion pricing for ML corridors.

This book was released on 2020 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Express lanes or priced managed lanes provide a reliable alternative to travelers by charging dynamic tolls in exchange for traveling on lanes with no congestion. These lanes have various locations of entrances and exits and allow travelers to adapt their route based on the toll and travel time information received at a toll gantry. In this dissertation, we incorporate this adaptive lane choice behavior in improving the dynamic pricing and long-term planning models for managed lanes with multiple entrances and exits. Lane choice of travelers minimizing their disutility is affected by the real-time information about tolls and travel time through variable message signs and perceived information from past experiences. In this dissertation, we compare various adaptive lane choice models differing in their reliance on real-time information or historic information or both. We propose a decision route lane choice model that efficiently compares the disutility over multiple routes on an express lane. Assuming drivers’ disutility is only affected by tolls and travel times, we show that the decision route model generates only up to 0.93% error in expected costs compared to the optimal adaptive lane choice model, making it a suitable choice for modeling lane choice of travelers. Next, using the decision route lane choice framework, we improve the current dynamic pricing models for express lanes that commonly ignore adaptive lane choice, assume simplified traffic dynamics, and/or are based on simplified heuristics. Formulating the dynamic pricing problem as an MDP, we optimize the tolls for various objectives including maximizing revenue and minimizing total system travel time (TSTT). Three solution algorithms are evaluated: (a) an algorithm based on value-function approximation, (b) a multiagent reinforcement learning algorithm with decentralized tolling at each gantry, and (c) a deep reinforcement learning assuming partial observability of traffic state. These algorithms are shown to outperform other heuristics such as feedback control heuristics by generating up to 10% higher revenues and up to 9% lower delays. Our findings also reveal that the revenue-maximizing optimal policies follow a “jam-and-harvest” behavior where the toll-free lanes are pushed towards congestion in the earlier time steps to generate higher revenue later, a characteristic not observed for the policies minimizing TSTT. We use reward shaping methods to overcome the undesired behavior of toll policies and confirm transferability of the algorithms to new input domains. We also offer recommendations on real-time implementations of pricing algorithms based on solving MDPs. Last, we incorporate adaptive lane choice in existing long-term planning models for express lanes which commonly represent these lanes as fixed-toll facilities and ignore en route adaptation of lane choices. Defining the improved model as an equilibrium over adaptive lane choices of self-optimizing travelers and formulating it as a convex program, we show that long-term traffic forecasts can be underestimated by up to 45% if adaptive route choice is ignored. For solving the equilibrium, we develop a gradient-projection algorithm which is shown to be efficient than existing link-state algorithms in the literature. Additionally, we estimate the sensitivity of equilibrium expected costs with demand variation by formulating it as a convex program solved using a variant of the gradient projection algorithm proposed earlier. This analysis simplifies a complex express lane network as a single directed link, allowing integration of adaptive lane choice for planning of express lanes without significantly altering the components of traditional planning models. Overall these models improve the state-of-the-art of pricing and planning for managed lanes useful for evaluating future express lane projects and for operations of express lanes with multiple objectives

Available in PDF, EPUB and Kindle. Book excerpt: This report documents the development of a decision support methodology that accomplishes two objectives: (1) sorts out the relationships between managed lanes concepts and strategies, and (2) maps the knowledge territory in order to identify gaps. In conjunction with this particular research task, a user-friendly preliminary screening tool has been developed to assist the Texas Department of Transportation (TxDOT) in identifying managed lanes strategy options very early in the conceptual planning process. The framework for the decision support methodology is the backbone for the Managed Lanes Handbook, which offers the resources and guidance to develop a managed lanes project, addressing characteristics unique to individual facilities. This report also summarizes the evolution of managed lanes in Texas over the last five years, the legislative initiatives that have shaped TxDOTs current approach to implementation, and the gaps in the knowledge base that still leave many questions unanswered. At the national level managed lanes are a relatively new and emerging concept. However, TxDOT has led the nation in research and development with two highoccupancy toll (HOT) lanes and 10 freeway high-occupancy vehicle (HOV) facilities in operation and over a dozen managed lanes projects currently under development in 10 Texas cities. Even with the experience to date, there are still many unanswered questions related to the long-term operation of managed lanes and numerous unknown factors that will require further research and documented practical experience through diligent monitoring and evaluation of facilities as they are implemented.

Download or read book Digital Twin and Blockchain for Smart Cities written by Amit Kumar Tyagi and published by John Wiley & Sons. This book was released on 2024-09-11 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book uniquely explores the fundamentals of blockchain and digital twin technologies and their uses in smart cities. In the previous decade, many governments explored artificial intelligence, digital twin, and blockchain, and their roles in smart cities. This book discusses the convergence of two transformative technologies, digital twin and blockchain, to address urban challenges and propel the development of smarter, more sustainable cities. This convergence empowers cities to create real-time replicas of urban environments (digital twins) and secure, transparent data management (blockchain) to improve city planning, management, and civic services. In this application, the concept of a digital twin involves creating a virtual, data-driven replica of a city or specific urban systems, such as transportation, energy, or infrastructure. This digital twin mirrors the real world, gathering data from various sensors, IoT devices, and other sources to provide a holistic view of the city’s operations. Furthermore, blockchain technology offers a decentralized and tamper-resistant ledger for securely storing and managing data. In the context of smart cities, blockchain can ensure data integrity, privacy, and transparency, enabling trust and collaboration among various stakeholders. This book covers many important topics, including real-time city modeling; data security and the trustworthy storage of sensitive urban data; transparent governance to facilitate accountable governance and decision-making processes in smart cities; improved city services; disaster resilience (by providing insights into vulnerabilities and efficient resource allocation during crises); sustainable urban planning that optimizes resource allocation, reduces energy consumption, and minimizes environmental impact, which fosters sustainable development; citizen engagement; and much more. This book will not only provide information about more efficient, resilient, and sustainable urban environments, but it also empowers citizens to be active participants in shaping the future of their cities. By converging these technologies, cities can overcome existing challenges, encourage innovation, and create more livable, connected, and responsive urban spaces. Audience This book has a wide audience in computer science, artificial intelligence, and information technology as well as engineers in a variety of industrial manufacturing industries. It will also appeal to economists and government/city policymakers working on smart cities, the circular economy, clean tech investors, urban decision-makers, and environmental professionals.
