Lucie Parrot, eng.,M.eng., CSI, CVS
  • industrial engineer with over 25 years of experience
  • involved in product development projects
  • award for her “outstanding contribution” from the Canadian Society for Value Analysis.
  • with the society since its beginning
agenda
Agenda
  • Context
  • Mandate
  • Approach
  • Methodology
  • Results
mto context
MTO context
  • successfully used the VE Methodology, since 1998on design projects of highways
  • savings in excess of $100 Millions
  • limited use in other business areas
  • develop a new framework for an expanded and updated Traffic Volume Information System (TVIS2)
mandate
Mandate
  • analyse the functions of 6 existing legacy systems,
  • incorporate new required functions
  • eliminate redundant functions
  • evaluate potential options / FPS
  • highlight weaknesses in current business processes
  • Decide: acquire or develop of new system.
network
Network
  • 16477 km of highways
  • collection of data is done on a few specific road sections on a continuous basis
  • remainder of the sections according to a three year program.
  • One of the most important statistics AADT- Average Annual Daily Traffic.
responsibilities
Responsibilities
  • Head Office :
    • the permanent counting program
    • publication of traffic volume data and statistics.
  • Regional Traffic Offices:
    • collecting and processing of sectional traffic data on highway network
    • review of the preliminary data prior to the publication by Head Office.
actual systems
Actual systems
  • Inventory Count Management System (ICMS)
  • Regional Traffic Information System (RTIS)
  • Noon-to-Noon File Management System (NNFMS)
  • Permanent Counting Stations (PCS)
  • Matching Program (PCSFIT)
  • Traffic Volume Information System (TVIS)
situation
Situation
  • antiquated and need to be replaced.
  • written in 16-bit DOS, FORTRAN, dBaseIII+, and Better Basic
  • Some are mainframe applications while others are for stand alone PC applications that will not work in a modern computer environment
comparison
Comparison
  • publication of current traffic statistics is delayed by over 1 year.
  • US DOT’s are required to publish federally reported traffic data within 90 days of year end.
approach
Approach
  • Arrange Stakeholder workshops and user interviews facilitated by a CVS resulting in a functional tree and draft FPS
  • Prepare final Functional Performance Specification
  • Prepare a detailed questionnaire based on the FPS to interview 15 selected transportation agencies
  • Short List and visit 3 agencies for detailed analysis
  • Prepare report on findings and preferred solution from agencies / FPS
  • VE of business processes
methodology
Methodology
  • Analyze the functions of current processing systems in order to identify what needs to be included in the next generation system.
  • Identify functions of a higher level, by looking at the outside influence factors that have an impact on the design of the new TVIS2 system. (environmental analysis)
  • Organize functions in a functional diagram & FPS.

determine the needs
DETERMINE THE NEEDS
  • creation of a program scheduleaccording to rules set by frequency, dates, duration and method of collection including time intervals
  • maintenance or construction work must be known
  • inventory of sensors and equipment
  • add ad-hoc count requests
  • query and revision of the program
collect retrieve data
COLLECT / RETRIEVE DATA
  • programming, collecting/recording and retrieving of data recorded by monitoring equipment
  • upload and download information
  • stamp for time, location and type of equipment used, for traceability and for quality of data purposes
  • data entry screens
ensure quality of process
ENSURE QUALITY OF PROCESS
  • assessing integrity and quality of the acquired data
  • errors and anomalies are identified and edited
  • New: authentication of data and tracking of level of confidence
process data
PROCESS DATA
  • calculations, statistics, spreadsheets and graphs are prepared
  • match data to curves by pattern types
  • Projections done for uncounted locations
  • Estimates are also prepared
  • warrants are calculated
make results available
MAKE RESULTS AVAILABLE
  • preparation of reports
  • export of data
  • publication of information
  • help the users make good decisions
  • Real time data should be available
ensure reliability and continuity of system
ENSURE RELIABILITY AND CONTINUITY OF SYSTEM
  • respect standards and MTO architecture
  • Supportusers and owners
  • manage the system
  • legacy data need always to be available
  • make sure no suspicious or malicious activities take place

  • Utilize a current US-DOT Traffic Monitoring System as a basis for the new TVIS2 System
  • Purchase a Commercial Off the Shelf Traffic Monitoring system
  • Develop a new system based on the FPS developed for this project
system s integration
System’s Integration

First opportunity for system IT staff to evaluate FPS as tool.

Itwas concluded that this provided many valuable opportunities to bridge the gap between user and application developer.
