Guided by the federal highway administration （FHWA）, many states are promoting the implementation of transportation systems management and operations （TSM＆O） pro- grams. TSM＆O is traditionally managed by traffic engineers that focus on optimizing ef- ficiency and operations within a particular corridor utilizing common techniques such as re-timings and access modifications. With the emphasis moving towards maximizing current infrastructure, the practice of managing TSM＆O can be applied to all units and disciplines, within a transportation entity, for increased efficiency. One main reason of the stagnated integration is the lack of policies which could support the integration of TSM＆O strategies within the planning or design stages. This paper provides detailed guidance on how to apply TSM＆O strategies from the planning stages to the construction phase of any general transportation project. TSM＆O programs established around the nation are dis- cussed to understand the current initiatives underway and the best practices to create a robust and performance-based program. The developed TSM＆O project cycle process provides a detailed structure for the potential interactions between phases of a project and department staff as a key to ensure that the program achieves the highest level of opti- mization. Continuous evaluation must be undertaken by the agencies to ensure that theperformance of the system is at an optimal level. Developing performance measures, which accurately describe the objectives of the agency, is critical to ensure the plan to be brought to practice.

Implementation of blockchain technology in integrated IoT networks for constructing scalable ITS systems in India

BLOCKCHAIN-RESEARCH AND APPLICATIONS 2024年第2期5卷 99-125页

The implementation of blockchain technology in integrated IoT networks for constructing scalable Intelligent transportation systems (ITSs) in India has the potential to revolutionize the way we approach transportation. By leveraging the power of IoT and blockchain, we can create a highly secure, transparent, and efficient system that can transform the way we move people and goods. India, one of the world's most populous countries, has a highly congested and inefficient transportation system that often leads to delays, accidents, and waste of time and resources. The integration of IoT and blockchain can help address these issues by enabling real-time monitoring, tracking, and optimization of traffic flows, thereby reducing congestion, improving safety, and increasing the overall efficiency of the transportation system. This paper explores the potential of blockchain technology in the context of integrated IoT networks for constructing scalable ITS systems in India. The methodology followed is to develop a proof-of-concept blockchain-based application for ITS, implement the blockchain solution into the existing ITS infrastructure, and ensure proper integration and compatibility with other systems. Conduct thorough research and maintenance to ensure the reliability and sustainability of such blockchain-based systems. This research discusses the various benefits and challenges of this approach and the various applications of this technology in the transportation sector, including the green sustainability concept. The results find various ways in which such implementations of blockchain and IoT-Machine Learning (IoT-ML) can revolutionize transportation systems.

Output feedback control of pantograph–catenary system with adaptive estimation of catenary parameters

引用

Journal of Modern transportation 2015年第4期23卷 252-261页

With the increasing railway vehicle speed, pantograph--catenary （PAC） system has become an important part as its incidents still stand among the prin- cipal causes of railway traffic interruption. Indeed, when a rail vehicle moves, the pantograph should constantly press against the underside of the catenary. Nonetheless, it is difficult to get around the complexity of the physical interaction between the pantograph and the contact wire, which could deteriorate the quality of the electricity transfer. Thus, PAC system performances could dramati- cally be reduced because of bad current collection. Therefore, in this paper, we present an output feedback solution in order to design an active control of PAC system. The proposed solution is based on the backstepping control and an adaptive observer that estimates both the （unknown） catenary parameters and the system state. All synthesis steps are given and the closed-loop analysis shows asymptotic tracking behavior regardless of the time-vary- ing catenary stiffness. Furthermore, a numerical example shows that the PAC contact can be regulated with desired effect.

High-speed rails （HSR） are playing an important role in the transportation systems across the world. In Japan, the Shinkansens carry more than 250 million passengers each year. In Europe, the trans-European high-speed rail network is in operation. At the beginning of 2011, U.S. President has called for a six-year, $53 billion budget for HSR. Nowadays, China has built the world＇s largest HSR network of over 4 600 miles.
