The Interstate 15 (I-15) Express Lanes project is approximately 14 miles long and consist of inside widening along I-15 between Cajalco Road and State Route 60 to provide tolled express lanes in each direction. ADVANTEC was responsible for PS&E Design of all electrical elements for Caltrans Transportation Management System (TMS) and RCTC Toll Collection System (TCS) including ramp metering, traffic monitoring stations, closed circuit television cameras, changeable message signs, census stations, wireless detection systems, and fiber optic backbone.

Housing development project in Santa Clarita, CA. ADVANTEC was in charge of designing signing and striping, traffic signal, street lighting and interconnect plans.

ADVANTEC was responsible for the preparation of plans, specifications and engineer’s estimates (PS&E) for ADA ramps upgrade, Intelligent Transportation Systems (ITS) upgrades including, traffic signal equipment and detection upgrades, fiber optic communications, and traffic signal timing and coordination along Imperial Highway from San Gabriel River to Shoemaker Avenue.

This project consists of providing traffic engineering and environmental services for the preparation of plans, specifications, and estimates (PS&E) for 93 signalized locations including construction support and environmental documentation and approvals for the City’s Traffic Signal Upgrades (HSIP Cycle 9) project.

Project to upgrade 12 existing changeable message signs which help communicate and navigate visitors to the Anaheim Resort Area. ADVANTEC prepared the specifications and engineer’s estimates (PS&E), coordinated a structural analysis of the existing infrastructure, upgraded the sign structures with new signs, and connected the new system to the existing infrastructure. Project was constructed and installed with zero RFIs.

The project consists of providing traffic engineering, civil engineering, and environmental services to secure environmental documentation approvals; Caltrans encroachment permits; and preparation of plans, specifications and estimates (PS&E) for 14 signalized locations including construction support for the City’s Traffic Signal Improvements (HSIP Cycle 8) project. The purpose of this project is to improve safety and visibility of the traffic signals by upgrading traffic signal equipment and signing/striping to the latest standards, protected left turn phasing, ADA compliant access ramps, and install advanced dilemma zone detection for high speed approaches at the following 14 intersections. The proposed project improvements include, but not limited to: removing existing five-section protected/permissive signal heads, mast arms, and signal poles; installing signal heads on new mast arm and traffic signal pole; implementing advanced dilemma zone protection; installing ADA compliant pedestrian access ramps; providing new striping and signing; and establishing connections of the traffic signals to the Traffic Management Center (TMC) at City Hall. This project also requires the preparation of environmental documentation to meet the National Environment Policy Act (NEPA) and California Environmental Quality Act (CEQA) requirements and clearances. In addition, this project includes a left-turn phasing and level of service (LOS) analysis to determine the left-turn phasing, as well as signal timing upgrades that are associated with the implementation for advanced dilemma zone detection system.
