GHZ Communications handles Design Mangement for a scheduled three year (2011-2014) effort to purchase, install, and implement Security Video cameras in all buses, mobility vans, and train cars for the Metropilitan Transit Authority (MARTA). The project involves the development of the RFP document, evaluation of vendor’s equipment, evaluation of vendor’s technical proposals, selection of vendor equipment, deployment, and acceptance of the implementation.
Up to 12 cameras will be installed on a total of 907 vehicles and train cars for the Mobile CCTV project. The CCTV Expansion Project will design and deploy an 802.11n wireless network at garages, terminal, and rail stations for the purpose of accessing event driven video recordings over the wireless link.
GHz Communications provided four years of technical project management and consulting help to Metropolitan Atlanta Rapid Transit Authority (MARTA) to achieve final acceptance of TrapezeITS Transit Master AVL/APC implementation. This effort involved developing methodologies and tools to quantify the overall system health and performance of RF, wireless, infrastructure, Transit vehicle on-board equipment, and ITS information technologies. GHz Communications provided technical leadership in developing methodologies to utilize new technologies including Automatic Passenger Counting (APC), Automated Vehicle Annunciation (AVA), Automated Destination Signs, Automated Vehicle Fault and Alarm Monitoring, Single Sign-On to fare collection system, Schedule Adherence for both fixed and dynamic scheduling systems and real time information exchanges with MARTA regional partners.
This project involved the IP design, lab pilot testing, proof-of-concept field test, and recommended configurations of a regional 4.9 GHz wireless network based upon an Connected Vehicle concept. This network supports the Bus RapidRide corridors for King County Metro to provide ITS Architecture based on connectivity to/from King County main campus facilities, Incorporated within this network are traffic signal controls, traffic signal privatization, real time arrival information signs, fare collection technology, enhances location reporting by transit vehicles, and backhaul for future security video cameras.
This network is the first implementation of the US DOT concept of the Connected Vehicle in the nation. GHz was responsible for three distinct strategic planning activities for this project: selection of 4.9 GHz Public Safety frequency for wireless access medium, development and demonstration of a proof-of-concept for the design, and development of a seamless migration path for the existing 802.11g wireless equipment to use the new medium.
GHz Communications is responsible for design and deployment of a 4.9 GHz wireless network along the Rainier corridor of Seattle. This corridor will demonstrate interoperability with the King County Metro Rapid Ride corridor vehicles. In this project, vehicles from Metro’s transit fleet that are equipped with the 4.9 GHz mobile client will be recognized by City of Seattle maintained roadside access points and data collected by the City of Seattle will be exchanged with King County operations to provide sign updates for both Metro and City of Seattle facilities and traffic signal prioritization for transit, public safety, and emergency vehicles within the City of Seattle.
This project was part of a larger strategic planning effort by GHz Communications in coordination with DKS Associates, which involved evaluation of planned ITS architecture for traffic signal, CCTV, variable message signs, weather stations, and ATIM, as identified in the Deschutes County ITS plan near Bend, Oregon. The ten-year plan involved wireless links proposed for 4.9 GHz point-to-point and point-to-multi-point links. RF sites were established, which required an RF path analysis that included projected elevation profile, installation tilt, azimuth, and link budget, wireless equipment recommendations, and mounting instructions for the network elements.
Also included in this project is a second wireless deployment, GHz Communications was responsible for not only the RF survey and design, as in the Bend project, but the pilot testing, proof of concept, and deployment of a dual band 4.9 GHz and 5.8 GHz wireless mesh backhaul to ODOT’s Traffic Management Operations Center. In the deployment, video from bridge security cameras, is remotely accessible on the 5.8 GHz mesh and ITS Adaptive Traffic Signs and Speed Sensors are accessible on the 4.9 GHz band.
