Short Biography:
Mr. Venglar has been involved with research activities at the Texas
Transportation Institute (TTI) since 1992. His primary responsibilities
have been focused in the areas of transportation operations modeling,
analysis and evaluation. In recent years, he has served as a project leader
on research in the areas of exit ramp speed warning signing, advanced
warning of signals beyond vertical curves, truck lane and truck roadway
analyses, managed lanes traffic operations, railroad preemption of traffic
signals and freeway ITS evaluation. In performance of myriad traffic
engineering research and transportation modeling studies, Mr. Venglar has
developed a broad experience base using traffic analysis (PASSER II/III/V,
Synchro, HCS) and transportation modeling (CORSIM, VISSIM, TransModeler,
Integration, SimTraffic, DynaSmart-P) tools.
Mr. Venglar's career experience also includes leadership roles in efforts
to develop a real-time control and optimization algorithm for signalized
diamond interchanges, in an investigation of freeway incident management in
Austin, Texas, and in a study to determine the impacts of light-rail
transit in at-grade signalized environments. His professional development
activities include developing and teaching courses for TxDOT in the areas
of traffic signal preemption, signal optimization and transportation
simulation modeling, and he taught a National Highway Institute course in
computerized traffic signal systems. Mr. Venglar is an active local and
national member of the Institute of Transportation Engineers (ITE),
including past service in local leadership positions and active membership
on ITE committees in several traffic engineering areas.
