Transportation Consultants RE C E IV E D NOV 0 6 1*6 MEMO rr,e Planning & Engineering, Inc. November 5, 1996 Project No.: 04 To: Steve Fitzsimons, CCS Planning & Engineering, Inc. From: Gary Kruger, TJKM Transportation Consultants 14" 6-A-k� Subject: Detailed Generation 15 Software Proposal - East 14th Street/Mission Boulevard TCM In response to your request, this memo provides a more detailed presentation of TJKM's proposal to develop Generation 1.5 Signal System software for the East 14th Street/Mission Boulevard TSM project currently under design by CCS. This memo supersedes the proposal transmitted to you on September 17, 1996. This updated proposal: A) provides an overall view of the functions (modules) of the Generation 1.5 software as it relates to signal systems, B) defines specific capabilities and functions of the Generation 1.5 software, C) indicates which of the software modules can be independently developed by TJKM, which modules will need cooperation and assistance from the developers of CT Net, and which modules will need cooperation and assistance from Econolite (it is assumed that cooperation and assistance with CT Net is a given, and cooperation and assistance from Econolite is likely, but not guaranteed), and D) identifies the costs and the steps needed to improve the City of Campbell TIS (this memo assumes that all rights to TIS will be granted to the public by the City of Campbell if the enhancements to TIS described in this memo are also provided to the City of Campbell). A. Overview of Linkages Between Signal Systems and Generation 1 S Software Figure 1 on the following page shows the generalized functions and data flow of both signal system software and Generation 1.5 software. Signal system software (eg., CT Net, Quicnet, Traconet, Econolite Zone Master IV, Econolite TMS, etc.) provides centralized control and communications between the central signal monitor and field masters and single intersection controllers and detectors. It is this software that eases the tasks of coordinating signals in a specific group of signals by providing the traffic engineer centralized access to controller settings and also provides a common time base for a system of coordinated signals to maintain coordinated signal timing plans. Signal system software (ie., the central system monitor) is not needed for signal coordination, nor, actually, is interconnection of signals, but both the central system software and interconnection greatly improve control and performance of coordinated signal systems. 4637 Chabot Drive, Suite 214, Pleasanton, CA 94588-2754, (510) 463-0611, Fax (510) 463-3690 Pleasanton .
