Abstract  :Over the last few years, we are seeing a convergence of technology, data, analytics and new modeling approaches in transportation systems leading to efficient and sustainable cities. This trend is expected to continue with unprecedented advances in artificial intelligence, telematics, growth of
connected and automated technologies and availability of high velocity spatio-temporal data. These advances promise significant benefits in the realization of smart mobility and sustainability; however, many challenges exist on the research frontier. This talk with present ongoing research and insights from information rich transportation environments and innovations in connected/autonomous vehicles.

Abstract: Newer technologies and high market penetration of personal communication systems along with the advent of autonomous and connected vehicle systems bring up many new possibilities for different paradigms of operation in transportation systems. Facilitated by significantly more peer-to-peer (P2P) communication, users in the future can consume transportation supply with more complete information on individual heterogeneity in utility satisfaction. Several possibilities exist in such a world of shared economy, with regard to using road and vehicle space in a temporally efficient manner. Breaking the traditional First-Come-First-Served paradigms with P2P monetary exchanges to compensate for utility disparities can improve system and user level efficiency. Car-sharing and ride-sharing are two of the more well-known systems of relevance. Autonomous vehicles bring up another dimension in terms of shared ownership as well. There is also recent research in collaborative negotiated consumption of other elements of transportation supply such as signal timings, and lane space availability. This presentation focuses on the possibilities, and discusses recent research into such mechanisms for signal and lane usage, and ride-matching in shared-ride systems. It also describes the associated pricing and behavioral issues where economic concepts such as envy-freeness are introduced as a basis for such schemes to be user-driven and equitable, without system level mandates.

Abstract  :Major disruptions are taking place in how people move in cities. Rapid developments in Information Technology have given a thrust to shared mobility systems that hold the promise of massive transformation in the mobility systems and help deal with the current problems of congestion, pollution and increasing road accidents. Falling battery prices, increasing emphasis on renewable energy have made electric vehicles a lot more attractive than was considered feasible in the past. If these developments are to be effectively leveraged, national policies need to be modified to align with these developments. Old enactments need to recognize the new reality and embrace them. Research needs to ensure that developments in other countries are not merely copied in India but we adapt them to meet our unique needs. Good research can help guide policy in the right direction. However, it needs to be application oriented and have a sense of urgency.

Abstract:

The presentation will talk about the various methods for traffic flow modeling under Indian traffic conditions highlighting their advantages and disadvantages, taking specific applications as an example.

Abstract: In this talk, the various stages of a highway project namely, identification, formulation, appraisal, implementation, monitoring and evaluation, the associated issues, and possible solutions will be discussed. The considerations and the view-points expressed by the government as well as by the technical experts, related to the project identification, inception of new projects, asset creation, maintenance priorities on the existing pavement structures etc. will be highlighted. The issues related to land-acquisition, and introduction of new technologies will be mentioned. Finally, the need of scientific approach to select the new project and upgradation of existing assets and the need of collective effort in project execution will be emphasized.

About the speaker: Mr. V.K.Singh worked in Public Works Department U.P. (PWD-UP) for nearly 36 years. He retired as Engineer-in-Chief and Head of the Department in September 2019. Under his leadership the government saved nearly Rs.942 crores in the year 2018-19 by implementing two new technologies in pavement construction namely, cement treated base and emulsion treated base. Adoption of these new technologies also lead to the savings of nearly 30.0 lakh tonnes of stone aggregates and nearly 1.2 million tones carbon emission during the year 2018-19. Mr. Singh is a member of various technical committees appointed by Indian Roads Congress, namely, Flexible pavement and Airfields of Running (H-2), Road Safety and of Design (H-7), Maintenance and Rehabilitation of Bridges (B-8),  and Reduction of Carbon Footprint in Road Construction and Environment  (G-3).
