BAI developed complete construction plans, specifications and cost estimates for new and/or modified traffic signals at more than 200 intersection locations, throughout the State. The design services included field investigations and the establishment of associated traffic control device needs, determination of safety standards and funding requirements. Traffic signal assignments were developed as an “Insert” to a formal construction project (i.e. highway improvement); under an “Area-wide” agreement, which involved construction by an existing SHA contractor; or as a “Stand Alone” contract bid procurement award. Several of the signal designs were classified by MDOT as “STAR” projects, which required the design services be completed within one week of initial notification.
The signal design services included:
| Type/Size/Location of Signal and Poles Proposed Utility Service Needs
Controllers, Cabinets and Wiring Accessory Devices and Equipment Site Distance and Visibility Needs Structure Foundation Design Vehicle Detection-Loop, Video or Radar Signal Pre-emption; Flashing Beacons |
Field Survey/Intersection Mapping Pedestrian Countdown Signals
Contract/Equipment Summary Sheets Signal Systemization, Simulation ADA Compliance Mitigation Clear Zone, Traffic Barrier Analysis Overhead Clearance Validation MUTCD/AASHTO Compliance |
