Mr. Steve Fitzsimons Page 5 November 5, 1996 B. Specific Capabilities and Functions of the Generation 1 S Software (TIS) Assuming that the signal system and/or field master/controller output includes the basic data, TIS will be able to do the following functions: • Permanent Counts: TIS shall be capable of acquiring volume and occupancy data and storing it in an efficient database that defines volume data by location and movement (both turn counts and directional counts) in 15 minute increments, 24 hours a day, 365 days a year. This program, called COUNTS already exists in the Campbell TIS and the Pleasanton signal system. The engineer can easily define sorting variables such as direction, times of day, different periods from 15 minutes to one day, day of week, weeks, months, or user -defined, and total, average and calc7ilatP ct �nriarri (jPyiarinn-s for the dates being Wnaly'..e...'i, a1'—th C.01,Ull- gild across rows. COUNTS is a binary, DOS program and is very memory -efficient and fast It is recommended that this program be retained as DOS in TIS rather than conversion to a Windows 3.1 or Windows 95 program such as Microsoft Access to save space and speed program execution. Processing a year of 15 minute -increment turn counts at an intersection with COUNTS takes only a few minutes on a 486, while processing the same period with Windows 3.1 or Windows 95 could take far longer. (COUNTS, however, can be run in a Windows 3.1, Windows 95 or Windows NT environment.) This is especially important because initial system communications will be by modem and phone lines between the Caltrans computer and city computers. Traffic Database will not be integrated into any city's or Caltrans' GIS with this contract. Enhancements to the existing COUNTS program (Traffic Database) will include detection of suspicious data on the basis of a moving average or by quality control curves for an ongoing process. Signal Timing: TIS will, to the extent that signal controllers and masters can provide the data, access, process and store actual signal timing information including actual splits by cycle and for a 15 minute period, actual pedestrian actuations by phase and actual offsets averaged over a 15 minute period. TIS will not store data relating to how each phase is terminated (ie., force off, gap out, max out, etc.), although this capability could be added later. • Signal Events: TIS will store available signal hardware and software failure events by time of onset and duration as related to location and phase. This information may, at the choice of the engineer, act as a filter to eliminate data from averages and other statistics of system performance, and as input to the Synchro modelling software. Events such as a stuck detector, inoperative detector, signal flash, power off, loss of coordination, loss of communication, etc. will be stored in a database developed to accommodate events commonly reported in 170, Traconex and Econolite systems. Reports will be formatted so that all systems have a common event report for both hard copies as well as for direct use in the data compiling program in TIS. Data Acquisition and Compiling: TIS will interface with the automated data acquisition programs in the signal system software (this is TDAQS in Traconet software). Automated data acquisition is simply a scheduled and routine computer access and uploading (via hardware or dial -up modem) to controller data for permanent and complete, 24 hour a day data records of controller data (counts, actual timing and events). If these capabilities are not already present in CT Net and Econolite Zone Master IV, it will not be included in TIS with the basic budget for this contract. A supplemental budget and contract change order would need to be prepared for development of automated access and acquisition of data in these
