Mr. Robert L. Warnick -3- February 1, 1985 ( The purchase and installation' cost of the above hardware is estimated at $201,000. The engineering cost and contingency is estimated at $41,000. The estinlated total cost is $242,000. This 'installation work for monitoring has already begun and is partially complete at Hopyard Road/Stoneridge Drive and Stoneridge Drive/Denker Drive, however, the hardware requirements and costs for these two intersections are included in full in the information above. Data Analysis A micro-processor and accompanying software is needed to process the traffic volume counts and to perform intersection capacity analysis. A desktop micro-computer placed beside the existing City Hall master or connected with the master via a telephone line is suitable for receiving, storing, and processing the data retrieved from the detectors in the field. The procedures have been tested using an HP 150 personal computer, since the City has recently' purchased an HP computer system, and the tests went Very successfully. An IBM PC/XT connected to the VMS-220 master via a phone line has also been used successfully in testing the procedures. A special dedicated software package will be developed by TJKM to automate the process from the retrieving of data to the printing of level of service ~ {. reports. An HP 150 or an IBM PC/XT is recommended for handling the processing and calculation tasks with the use of TJKM developed software. The cumulative data can be saved either on the City's HP3000 or on floppy disks. The total software and hardware costs involved in establishing the data analysis process, including the cost of purchasing a personal computer, is estimated to be $15,000. 2. SYSTE~ EXPANSIO~t System Intersections To date, there are 46 existing signalized intersections located within the City of Pleasanton. (See Figure 1.) Twenty-two of these are interconnected w~th the system master VMS-220. As shown in FigUre 1, i~ the future there could be at least a total of 88 signalized locations in Pleasanton. Presently, there are 11 signalized intersections in the City of Dublin, and 17 additional signals are possible. That is, there vJill likely to be at least a total. of 116 signals between the two cities within the next 10 to 15 years. In orcler to adequately serve the signals in Dublin, the installation of a 25-pair cable running between th~ Pleasanton City Hall and the i~tersectioll of Dublin DoLllevard/DoLIgherty Road is recommended. The estimated total cost of the cable installation is $61,000.
