Scarinci R., Rast F., Bierlaire M. (2017). Needed reduction in mobility energy consumption to meet the goal of a 2000-watt society. Transportation Research Part A: Policy and Practice 101 ():133-148

Greenhouse gas emissions related to energy production is the main cause of climate change. Transportation accounts for 30% of the total energy consumption, and a reduction in the energy used for mobility is necessary. The 2000-watt society is an environmental concept that fixes a sustainable limit to the energy consumption in different sectors, including mobility. This paper evaluates the energy consumption in several mobility scenarios, and it assesses whether the goal suggested by the 2000-watt society is achievable. We investigate the social characteristics and travel habits of the population living in a case study area. Then, we calculate the modal shift induced by transportation policies such as car-sharing, car-pooling and car-free district. We evaluate the resulting energy consumption, and we compare it with the 2000-watt society limit. We conclude that only a set of measures combining car usage reduction, increase in walking and cycling, and reduction in the total travel distance can achieve the needed energy reduction.

Scarinci R., Markov I., Bierlaire M. (2017). Network design of a transport system based on accelerating moving walkways. Transportation Research Part C: Emerging Technologies 80 :310�328

Pollution, congestion and urbanistic considerations are leading to a change in the use of private vehicles in dense city centers. More frequently, the last-mile is covered with systems such as public transport, car sharing and bike sharing as well as an increase in walking and cycling. Following this trend, we assume a hypothetical scenario where the use of private cars is strongly limited in dense urban areas, and innovative transport modes must be used. This work investigates a futuristic system based on a network of accelerating moving walkways (AMW) to facilitate the movement of pedestrians in city centers where cars have been banned. Unlike constant speed moving walkways, AMWs can reach speeds of up to 15km/h thanks to an acceleration section. This paper presents a rigorous description of the system characteristics from a transportation point of view, develops a heuristic algorithm for the network design problem, and tests it on a real case study. Given a network of urban roads and an origin-destination demand, the optimization algorithm, which combines traffic assignment and supply modification, explores the trade-off curve between the total travel time and capital cost of the infrastructure. The results give practical insight on the possible dimensioning of the system, show the optimal network designs, and how these vary with a reduction of the available budget. This paper investigates for the first time the use of AMWs at a network scale, and provides results useful for analyzing the system feasibility. The results on travel time, investment budget and payback period indicates that AMWs could be an effective mode of transport in cities.

Scarinci R., Bahrami F., Ourednik A., Bierlaire M. (2017). An exploration of moving walkways as a transport system in urban centers. European Journal of Transport and Infrastructure Research 17 (2):191-206

Moving walkways (MW) have been imagined as a possible means of transport since the late 19th century, and this system has fascinated urban planners and engineers ever since. Contrary to what has been imagined, moving walkways are only used in transportation hub corridors, and not as a main transport mode in city centers. Today however, MWs are receiving increasing attention as a possible solution to congestion and pollution, as well as a catalyst for soft mobility. This paper explores the role of moving walkways as a transport system, and it presents an optimized design of a network of MWs in a city center. We review historical MWs, current installations and future possibilities, using different perspectives, from geography to urban planning to transport engineering. We discuss the way in which MWs influence how people inhabit the urban space, and we review this system in the context of history of urban planning. Then, we describe a technological development called accelerating moving walkways (AMW), i.e. MWs able to reach a higher speed than traditional ones. We develop an optimization framework to design a network of AMWs, and we apply it to a real case study. The results of the network design are a reference useful to discuss the feasibility of the system starting from an engineering perspective. We conclude that the use of MWs can facilitate the flexibility and spontaneity typical of pedestrian movements, and this system could be integrated in the mix of urban transport modes in city centers.

Accessibility based optimization of educational infrastructure networks

The aim of this project is to propose a methodology to assess and optimize educational infrastructure networks based on accessibility. In 2014, the World Bank launched the Global Program for Safer Schools (GPSS) with a focus on integrating risk reduction considerations into education infrastructure policies and investments. The GPSS aims to boost and facilitate informed, large-scale investments for the safety and resilience of new and existing school infrastructure at risk from natural hazards, contributing to high-quality learning environments. Understanding accessibility of school infrastructure networks is an important element to optimize risk reduction interventions as well as to improve the quality and efficiency of the educational service. To support this goal, the Transportation and Mobility Laboratory proposes a methodology to assess and optimize educational infrastructure networks based on accessibility; and proposes solutions to improve the performance of educational infrastructure networks. In other words, researchers will evaluate the risks based on the school network, including parameters like transportation network, home location of the students, mobility patterns... They will then provide a methodology in order to help direct investments to reduce the risks in case of disaster.

PostCarWorld: A Trans-Discplinary Multi-Dimensional Stimulation

The goal of this project is to explore the future of mobility through the role of the car. The main originality of this research is to raise the following problem: �What, if the world were a post-car world�. The basic idea is to define a hypothetical situation where the place of the car would have been dramatically reduced and to use qualitative and quantitative simulation methods to examine the consequences of this initial hypothesis. The research is based on the idea that by simulating the future through scenarios we can understand the present better. This project is fully interdisciplinary and trans-disciplinary. It brings together social sciences, engineering sciences, urban planning and urban design in six different laboratories associated to three different universities. The role of TRANSP-OR in this project is to study and optimize an innovative transport system based on accelerated moving walkways (AMW). Differently from constant moving walkways, AMW can reach speeds up to 15km/h thanks to an acceleration section. The project aims to identify the optimal design of a network of AMW using optimization. A network of accelerated moving walkway in a car-free urban environment may present an innovative solution, and this project could delineate the system feasibility.

Speed profile of an innovative catenary-free electric bus, Valentin Axel Olivier & Nicolet Adrien (Civil Engineering)

Supervision: Riccardo Scarinci, Virginie Lurkin, Michel Bierlaire
The TOSA bus system is a revolutionary catenary-free electric bus concept that includes small short-range on-board batteries and a series of fully automated fast charging stations installed at some bus stops. The automatic fast-charging stations partially replenish the bus batteries in a few seconds whenever a bus arrives at the bus stops, while avoiding any interference with the bus schedules and operations. This system has been defined during the project myTOSA 1.0 and implemented in a pilot test in the city of Geneva in 2013. The project myTOSA 1.0 is currently extended by the project myTOSA 2.0. myTOSA 2.0 is composed of several modules, the most relevant for this semester project is the traffic simulation. The traffic simulation represents the movement of the buses in a network, and requires a representation of the infrastructure as an input. This project aims to define the typical speed profile of an electric bus moving in an urban network. The speed profile includes acceleration and deceleration patters for different driver behaviour, network configurations and traffic levels. The influence of traffic lights, bus priority, roundabouts on the speed profile should be investigated. The first step to achieve this aim is to define the probability distribution of the number of intersections crossed by the bus. This step is necessary to complete this project successfully. Further steps in the directions of the definition of the speed profile are considerate optional. Methodologies from transportation modelling, geographical information system (GIS) and programming (MATLAB) will be used for completing this project.

Measure of user-oriented service variability in hubs, Anouk Allenspach and Dieynaba Dia (Civil Engineering)

Supervision: Nicholas Molyneaux, Riccardo Scarinci, Michel Bierlaire
This project's goal is to explore the service variability (reliability) in public transport hubs. Three operator oriented service characteristics are common in literature (robustness, reliability and punctuality). As these measures are operator oriented, they might not reflect actual level-of-service (LOS) experienced by users (pedestrians). To account for this difference, user-centered measures will be defined then observed using an already secured data set. Some examples of variability measures are OD travel time, passenger transfer times, passenger waiting times, train punctuality, etc. The main data sets used for this project is the pedestrian tracking data from the Lausanne and Basel train stations and possibly some effective train time tables.

Energy consumption of an innovative catenary-free electric bus, Xiaoran Yu

Supervision: Riccardo Scarinci, Yousef Maknoon, Michel Bierlaire
Electric busses help to decrease pollution in city centers. However, they need to be constantly attached to a power source. This limits their mobility and brings visual pollution due to continuous catenaries throughout the city. Focus of this project is a revolutionary catenaryfree electrical bus that includes short-range on-board batteries and a series of fast charging stations installed at some bus stops capable to charge the bus batteries in a few seconds without interference with the bus schedules. This project aims to develop a traffic simulation of this electric bus moving on a simple road network. A discrete event simulation representing the fundamental components of the system (e.g. bus, passengers load, on-board battery, charging station, storage level) should be developed, calibrated and validated using traffic data (such as number passengers on board, traffic and congestion information). Then, key indexes representing the system performance should be defined (e.g. travel time, dwell time, battery charge level). Methodologies from transportation modelling, simulation and programming (Java) will be used for completing this project.

Solar Decathlon: strategies for a sustainable mobility to achieve the goal of a 2000-Watt society, Charles Albert Jeanbart (Civil Engineering)

Supervision: Riccardo Scarinci, Michel Bierlaire
Solar Decathlon is an international competition that challenges twenty university teams from around the world to build and operate solar-powered houses. This project is part of the EPFL multidisciplinary team of students participating at this competition. The global objective is to transform a regular district in Fribourg into a sustainable eco-district using the solar-powered building as an activator. This building would promote sustainable actions, reduction in energy consumption and soft mobility. This project aims to evaluate the necessary strategies to incentive sustainable mobility inside the district. The goal is to suggest concrete actions that would incentive the modal shift toward more sustainable modes of transport. The effects of these strategies should be quantified and analyzed. The total energy consumed for mobility should respect the limit suggested by the 2000-Watt society. This concept proposes a way of living where nobody consumes more than a continuous 2000 W in comparison with the 6000 W currently consumed in Europe. Knowledge of transportation systems, environmental impacts and strong quantitative analysis skills are required to complete this project. The student will also interact with the other members of the Solar Decathlon competition.

Accelerating moving walkways as a transport mode of the future: system optimization and management, Alexandre Petit

Supervision: Riccardo Scarinci, Michel Bierlaire
In a hypothetical future where the use of private cars will be limited in cities, the need for movement will be satisfied by a mix of transport modes such as public transport, cycling, walking and other innovative systems. One of these possible futuristic systems, focus of this project, is an urban network of Accelerating Moving Walkways (AMW), i.e. a moving conveyor system for pedestrian similar to the one used in airports capable to reach speeds up to 15km/h. This project aims to optimize the network design of this innovative transport system of AMWs on the city of Geneva. Given the origin-destination demand, pedestrians are assigned to the city road network in order to obtain route choice and trip distributions. This information is used to identify the optimal configuration of link equipped with AMWs and their capacity. For this, a specifically developed optimization framework is used. Empirical mobility data and the road network (both already available) should be used as input of the optimization framework. Methodologies from mathematical optimisation, traffic assignment, programming (MATLAB) and Geographic Information Systems (GIS) will be used for completing this project.

Pedestrian movement in train stations: modeling speed-density relationship for different classes of passengers, Laure Emma Rosine

Supervision: Marija Nikolic, Riccardo Scarinci, Michel Bierlaire
The increased number of passengers in train stations is causing congestion not only on trains, but also on platforms and underpasses. To better design and manage these infrastructures, pedestrian movement should be understood and modeled accurately. Fundamental Diagram (FD) plays an important role in the representation of pedestrian dynamics. FD models the relationship between density of pedestrians and the speed at which they are able to move. This macroscopic model represents the average behavior and does not take into account differences among pedestrians. They can differ in terms of their purpose of the trip (e.g. business/leisure), personal characteristics (e.g. age, gender), presence of luggage, etc. This heterogeneity can lead to different walking behavior of pedestrians and should be adequately modeled by the FD. This project aims to develop a Multi-Class Fundamental Diagram (MC-FD) assuming the existence of different classes of passengers in a train station. As a case study we will use the Lausanne train station where detailed pedestrian trajectories have been collected. The key elements of the project are: (i) literature review of MC-FD for both pedestrians and vehicles; (ii) development of the modeling assumptions employing empirical, qualitative and sociological considerations; (iii) model specification; (iv) sensitivity analysis, calibration and validation of the proposed model based on empirical data. Knowledge of statistical mathematics and familiarity with programming (MATLAB) are required.

On this scenario, the optimal configuration of link equipped with AMWs and their capacity is define. For this purpose, a specifically developed optimization framework is used, and it should be applied to a real city. Lausanne presents appropriate transportation and geographical characteristic to be used as a case study. Empirical mobility data and the city network should be used as input of the optimization framework.

Optimisation of the network design of a futuristic transport system based on moving walkways, Guillaume Lopez

Supervision: Riccardo Scarinci, Jianghang Chen, Michel Bierlaire
In a hypothetical future where the use of private cars will be limited in cities, the need of movement will be satisfied by a mix of transport modes like public transport, cycling, walking and other innovative systems. One of these possible futuristic systems, focus of this project, is an urban network of moving walkways, i.e. a moving conveyor system for pedestrian like the one used in airports. This project aims to study and optimize the network design of this innovative transport system of moving walkways, exploring various network configuration and system characteristics to understand which specification could satisfy at best the increased demand. Given the origin destination demand and trip distribution, the variables of the optimization problem should be defined such that indexes of performance, e.g. overall traveling time and cost, are minimized. Example of design variables for this innovative transport system are: number of links to be equipped with moving walkways, moving pathway speed and system capacity that can be related to energy consumption and construction cost. Methodologies from mathematical optimization, transport network design, simulation and scripting will be used for complete this project.
