SRF has an experienced team of engineers ready to maximize the efficiency and safety of your  arterial roadways. We have helped agencies across the Midwest tackle retiming and optimization projects for corridors and grids ranging in size from just a couple of signals to more than 50. We work with our clients to determine the performance measures most important to success and then develop solutions to achieve those goals, whether they be reduced vehicle travel time for a high-volume arterial, reduced person-delay for a bus rapid transit line, or reduced crashes on a high speed arterial. Our services include:

  • Front page signal timing and MUTCD compatibility updates
  • Video and loop detection optimization
  • Coordinated signal timing
  • Traffic responsive and adaptive signal timing operation
  • Emergency vehicle and railroad preemption (EVP)
  • Transit signal priority (TSP)
  • Flashing yellow arrow (FYA) related services
  • Traffic signal controller data entry, implementation, and field fine tuning
  • Synchro/SimTraffic, VISSIM, and Vistro Modeling and Optimization
  • Before/after evaluation and benefit/cost analysis
