Topic of presentation : Modelling Traffic Streams in Two-Dimensions.

Abstract : Traffic dynamics is typically represented and modelled with time and longitudinal distance as the two dimensions. In this world vehicles move in a line over time; episodically they change from one line to the other. In such a world features like lane width, lateral clearance, curvature, steering angle, lateral closeness of other vehicles, etc. cannot be represented as the lateral dimension does not exist. Consequently, neither dynamics of disorderly traffic streams, where vehicles in a stream are not arranged in lines but spread somewhat haphazardly in the road space, nor effect of geometry on traffic stream (disorderly or otherwise) behaviour can be modelled using the one (spatial) dimensional framework. Realistic traffic stream models must represent space using both the longitudinal and lateral dimensions. In this talk I explore the past, present and future of two dimensional models of traffic dynamics both at the microscopic and macroscopic levels.

Topic of presentation : Data Considerations for Connected and Automated Vehicles and Infrastructure Systems

Abstract :Data exchange between vehicles and infrastructure elements is integral to connected, automated vehicles and infrastructure systems (CAVIS) operations. Key data include extent and conditions of the infrastructure, user and vehicle characteristics, user-vehicle-system interactions. Considerations include temporal and spatial resolution, accuracy, relevance, timeliness, risks, and threats. The presentation will highlight data needs, considerations, and concerns from the perspectives of CAVIS users, infrastructure system owners, operators, and managers. The comments will also touch upon sources for such data, future opportunities, and limitations.

Topic of presentation : User Exchanges of  Transportation Supply for Efficiency in a Shared-Connected-Autonomous Future

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.

Topic of presentation : Safer Highways and Urban Roads in India: Challenges in Standards and Priorities

Abstract: In India, Road Traffic Injuries continue to be one of the leading causes of death, disabilities and serious injuries. As per MoRTH‚Äôs Road Accidents in India (2017) Report, a total of 464,910 road accidents were reported claiming 147,913 lives and causing injuries to 470,975 persons. MORTH had set a Vision 2020, ‚ÄúTo make the transport on roads efficient, safe and sustainable. To reduce the fatalities on roads by half compared to 2010 reported deaths.‚ÄĚ However, this remains a distant goal as the number of fatalities are in fact on the rise. As a country we are nowhere near the target we had set for ourselves. In 2010, the number of accident deaths reported was 134,513 and in 2017 the same figure was 147,913. Instead of reduction in deaths as per the Vision, the accident deaths have increased by 10%. In the context of this rising number of fatalities and injuries on Indian Highways and Urban roads, the role of current design standards is explored. Engineering theory suggests that road designs - lane width, shoulder presence, number of lanes, median design - influence driving behaviour (operating speeds, lane changes etc.), therefore, one could expect that roads themselves play an important role in road safety, and improved geometry design and infrastructure could in turn help to improve road safety. Are current road standards adequate to meet the safety requirements of Indian traffic?

Topic of presentation : Aligning policies and research agenda to the emerging paradigms in urban mobility

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.

Topic of presentation : Performance-Based Bituminous Mixtures Testing - The Past, Present, and Future


Synopsis of the talk: Mechanical characterization of bituminous mixtures for quantification of performance has come a long way in the last several decades. From the rudimentary mix design based testing procedures used in the 1950s, the current test methods and post-processing techniques use advanced material testing that takes into cognizance the complex response of bituminous mixtures. 


In this talk, I discuss the innovations under three different broad areas. The first is related to sample preparation techniques, and here I focus on the shear box compactor (ASTM D7981). Such compactors produce samples with minimal variation in density spatially. The second is related to the Asphalt Mixture Performance Tester (AMPT). From the original testing protocols for flow number and dynamic modulus, this equipment is currently used for fatigue damage quantification using a cyclic direct tension test and provides in the laboratory a compact UTM with the flexibility to design and execute a wide variety of test methods. Finally, I discuss the four-point bending test method for fatigue damage quantification and the challenges in the design of the jig as well as in the development of precise post-processing methods. 


At the end of the talk, I give indications on expected trends in material testing, and this includes non-contact measurement techniques for bituminous mixtures as well as model-based real-time performance characterization
