Mr. Steve Fitzsimons Page 10 November 5, 1996 • Task 2.6: Event Data (Econolite/Traconex) - write a program which converts event monitor data from signal controllers and Zone Master IV/I'MS and Traconet to Traffic Database input data. Resources: no need for independent meetings with Econolite and Traconex developers (see Task 1.2), writing program to convert controller event monitor data to Traffic Database format is 16 hours including debugging ($1,920) • Task 2.7: C6ntin2encv with Econolite and Traconex - additional meetings and additional programming may be necessary to fully gain access to the data in CT Net, Econolite and Traconex controllers, especially the various versions of each on the street. This task will be invoked in the event that initial meetings (Tasks 2.1 and 2.2) fail to complete all data samples and formatting questions and programming code to TJKM's needs. Resources: up to 48 additional hours are programmed for this contingency, subject to approval from CCS and the TOC prior to proceeding ($5,760). THIS TASK WILL NOT BE AUTHORIZED WITHOUT THE VOTED APPROVAL OF THE TOC AND JPA AND IS NOT INCLUDED IN THE BASIC PRICE FOR TIS OF $59,820. • Task 2.8: Enhance COUNTS - The traffic volume database program which is to be modified and extended to become the Traffic Database program will also be enhanced to perform additional statistical functions such as identification and flagging of suspicious data. This can be accomplished through "quality control charts" much as are used in industrial processes. For each permanent count being collected, Traffic Database will have 99% or 99.5% upper and lower control curves for the data stratified by 15 minute and hourly intervals and by day of week. When an individual data point (such as a 15 minute volume) exceeds the control curve, the incident will be flagged, and be removed from the calculation of averages and other statistics at the option of the engineer. Resources: This process will require examination of multiple combinations of conditions such as day of week, month of year, direction of flow by 15 minute and hourly conditions, so there will ultimately be a sizeable number of control curves. The program will automate this almost completely, so the engineer will not need to be concerned with the statistical processes. TJKM estimates that 44 hours will be needed to fully develop Us sub -program at a cost of $5,280. Task 3 - Modelling and Timing Plan Generation Module: [TOTAL = $14,6401 Task 3.1: Stored Svstem Confi4uration - write a program which integrates the controller and system database with Synchro input data. Detectors are assigned a unique address or name at each intersection, and if there are three approach lanes, for example, on a southbound through approach, the detectors may be called LOCI, LOC2, and LOC3 for local (or stopline) Loop 1, 2 and 3 in the Number 1, 2 and 3 lanes. The database would convert these names to the appropriate one of eight possible phases at the specific intersection. In like fashion the remaining detectors would be assigned to the other phases as appropriate. It is more likely that advance detectors will provide the counts, or dual output loop amplifiers could also provide the counts for individual 6X6 stopline loops by allowing the loop to provide output to both local and system loop controller inputs. Additional information for the system would include the distances between intersections and intersection geometry as appropriate. The resulting file will be the input file for both Synchro and Traffic Database. It is this program that allows the engineer to link signal hardware with both Traffic Database and Synchro, TRANSYT and PASSER, and therefore, provides the ability to modify an existing system and to create new systems complete with volume and signal data in the central signal monitor
