Hybrid Dynamic Model for Transportation Electrification Published at the 2014 American Control Conference

Having studied the Abu Dhabi transportation systems for several years, it became clear to us that the true success of electrified transportation was its successful integration with the infrastructure systems that support them.  Left unmanaged electric vehicles may suffer from delays due to charging or cause destabilizing charging loads on the electrical grid. While many works have sought to mitigate these effects with advanced functionality such as coordinated charging, vehicle-to-grid stabilization, and charging queue management, few works have assessed these impacts as a holistic transportation-electricity nexus. To this effect, the 2014 American Control Conference (ACC) has recently published our paper on a hybrid dynamic model for transportation electrification.   Unlike traditional microscopic traffic simulators, this model considers stationary charging and online charging (while moving) as an integral part of the model rather than add-on functionality.  Thus is lends itself to usage by EV fleet operators to not just assess but also improve their operations & control.  It may also be used to coordinate the planning and operation transportation and electrical power infrastructure.

Turkish Electric Car w/ 500km Driving Range Hits Roads

At the LIINES, we have been conducting research on Transportation Electrification for quite some time.

At heart of the research is the electric vehicle, and its challenge is that it is both a transportation artifact that exists on our everyday roads as well as an electrical artifact that must connect to the power grid.   In the first full-scale case study of its kind, we have shown in Abu Dhabi that managing this dual nature means ensuring vehicle availability through charging while not imposing overly heavy demands on the grid.

One main challenge of electric vehicles is their driving range.  Many commercially available EVs only have a range of 150km — thus requiring charging once or twice a day.   With charging times of several hours, this means that a typical driver has to think very carefully how and when this EV will be practically used.

In contrast, a recent Turkish Electric Car developed at Istanbul University has demonstrated a 500km driving range in a tour from Istanbul to Ankara.  The “T-1” as the vehicle is called weighs a mere 500 kilograms and has a top speed of 120 kilometers per hour.  And while the vehicle looks sporty sleek, it has not neglected practicality with four seats and enough room for luggage.

With the T-1, the development team builds upon earlier successes including their 8th place finish in the 2009 global electric car competition held in Australia.

Abu Dhabi Department of Transportation, Mitsubishi Heavy Industries & Masdar Institute Joint Workshop

Following on the heals of their back-to-back conferences, Reem Al Junaibi and Prof. Amro M. Farid presented the results of their Abu Dhabi Electric Vehicle Technical Feasibility study in a joint workshop including participants from the Abu Dhabi Department of Transportation and Mitsubishi Heavy Industries.  They were joined by Mohammad Al-Hadrami and Prof. Sgouris Sgouridis who also investigated the socio-economic barriers to electric vehicle adoption.  The workshop was held on the Masdar Institute campus on December 17th 2013 and marked the official end to what has been a tremendously successful project demonstrating collaboration between public, private, and academic entities.

After the day-long workshop, Mitsubishi Heavy Industries hosted Masdar Institute and the Abu Dhabi Department of Transportation in a two-day workshop in Malaga, Spain on December 19-20 2013.  Malaga, Spain proudly marks itself as one of Europe’s leading smart cities. The Zem2All project, with the largest deployment of Electric Vehicles, is a testament to this achievement.

Prof. Farid continues to advocate Intelligent Transportation-Energy Systems.  In other words, the intelligent system consisting of monitoring, decision-making and dispatching functionality should have a transportation as well as energy management function.  Efforts are currently underway at the LIINES to develop models and control solutions which may be directly integrated into Intelligent Transportation-Energy Systems.  A full reference list of energy-transportation nexus research at the LIINES can be found on the LIINES publication page: http://amfarid.scripts.mit.edu

Reem Al Junaibi & Prof. Amro M. Farid present results of Abu Dhabi Electric Vehicle Technical Feasibility Study

In back-to-back conferences, Reem Al Junaibi and Prof. Amro M. Farid presented the results of their Abu Dhabi Electric Vehicle Technical Feasibility study.  Ms. Al Junaibi attended the 2nd IEEE International Conference on Connected Vehicles & Expo held December 2-6, 2013 in Las Vegas, NV, USA.  There, she presented the first published results of the study in the paper entitled:  “Technical Feasibility Assessment of Electric Vehicles : An Abu Dhabi Example”.  Meanwhile, Prof. Farid was invited to speak at the Gulf Traffic Conference held December 9-10 2013 in Dubai, UAE.

Both presentations revolved around the same theme.  The true success and feasibility of electric vehicles depends not just on the vehicle itself but also how it interacts with three large scale infrastructure systems:  the road transportation system, the power grid, and the intelligent transportation system.

Ms. Al Junaibi specifically presented some of the results of the study.  It considered twelve potential scenarios in which EV taxis were rolled out at a penetration of 3, 5 and 10% of road traffic with four possible charging system designs.  The results showed that if EV Taxi are to be deployed then their dispatching, queue management, charging and vehicle-2-grid stabilization activities must be simultaneously considered.  The ramifications of not doing so would be either degraded vehicle availability or high variable loads on the electric power grid or both.

Prof. Farid consequently argued that given the rapid push to transportation electrification and connected vehicles, intelligent transportation systems would better be considered as Intelligent Transportation-Energy Systems.  In other words, the intelligent system consisting of monitoring, decision-making and dispatching functionality should have a transportation as well as energy management function.

Efforts are currently underway at the LIINES are currently underway to develop models and control solutions which may be directly integrated into Intelligent Transportation-Energy Systems.  A full reference list of energy-transportation nexus research at LIINES can be found on the LIINES publication page: http://amfarid.scripts.mit.edu

Journal Paper Accepted at the IEEE Transactions on Intelligent Transportation Systems: An Axiomatic Design Approach to Passenger Itinerary Enumeration in Reconfigurable Transportation Systems

The LIINES is happy to announce that The IEEE Transactions on Intelligent Transportation Systems has accepted our recent paper entitled:  An Axiomatic Design Approach to Passenger Itinerary Enumeration in Reconfigurable Transportation Systems for publication. The paper is authored by Dr. Asha Viswanath, Edgar Eugenio Samano Baca and Prof. Amro M. Farid.

The topic of path enumeration in a transportation network has a long history.  As one can easily imagine, we have been asking: “How many different ways can I get from here to there?”  for a very long time.  The question is fundamental to many operations research problems and has new applications in the resilience of infrastructure systems.  So why a new approach to such an old problem?

Well, as the paper explains, the traditional graph theoretic based method lacks in four ways:

  1. it does not explicitly describe the different potentially redundant modes of transport.
  2. it does not explicitly address the implicit functions of parking, loading/unloading, or sitting at an intersection.  Naturally, if these “null-processes” were somehow unavailable you might be stuck along your path for a very long time.
  3. given its highly abstracted nature, traditional graph theoretic methods do not integrate well with existing engineering design methodologies.
  4. it does not explicitly describe changes or reconfigurations to the transportation network structure in real-time and hence has limited application to the design of real-time reconfigurable transportation systems.

Instead, this paper presents a passenger itinerary enumeration approach based upon Prof. Nam Suh’s axiomatic design theory for large flexible systems.  Here, the system form and function are both explicitly described to overcome all of the weaknesses mentioned above.  The work has immediate relevance to transportation systems that require real-time switching decisions in their network structure.  Furthermore, many transportation system life cycle properties functionally depend on path enumeration.

Further applications of this work can already be found on the LIINES publication page: http://amfarid.scripts.mit.edu
