DESCRIPTION:Dr Jack Haddad\,\n\nVisiting Professor\, Urban Transport Syste
 ms Laboratory (LUTS)\, EPFL\, Switzerland\,\n\nAssistant Professor\, Trans
 portation Engineering\, Civil and Environmental Engineering Faculty\, Tech
 nion – Israel\nEfficient traffic control and management of large-scale t
 ransportation networks still remain a challenge both for traffic researche
 rs and practitioners. Over decades\, control strategies have been proposed
  and applied for isolated or coordinated intersections in arterials\, whi
 le in the last decade several works have utilized the macroscopic fundamen
 tal diagram (MFD) for developing real-time control strategies to improve m
 obility and decrease delays in large urban networks. This seminar will foc
 us on enhanced modeling and advanced perimeter control of uncertain MFD sy
 stems for multiple-region networks.\n \nIn the first part of this seminar
 \, an enhanced accumulation-based model is developed by incorporating into
  model structure the time-delay (time-lag) effects as an important factor.
  The model incorporates state delay in the MFD output to improve the dynam
 ics\, i.e. representing wave propagation and travel time evolution within 
 the region. The reference model adaptive control approach has been impleme
 nted to allow us designing distributed adaptive perimeter control laws. Th
 e numerical results demonstrate the flexibility of the distributed adaptiv
 e perimeter controllers in handling different cases and various traffic si
 tuations with state delays.\n\nThe second part of this seminar will focus 
 on actuation failures in perimeter control. Actuation failures might cause
  severe system performance degradation\, if the control policy is not desi
 gned to compensate these failures. The component failures are uncertain in
  nature\, and very often it is impossible to predict in advance which comp
 onent may fail during system operation\, and when the component failure oc
 curs. An adaptive fault-tolerant distributed control scheme is developed f
 or a multi-region MFD system model. The control goal is to achieve a desir
 ed tracking performance with simultaneous (i) actuating control components
  failures\, (ii) model parameters uncertainties\, and (iii) unknown demand
  disturbances.  \n\nBio : Jack Haddad is an Assistant Professor of Transp
