Overview of ARTPLAN 2008

• What is ARTPLAN?
• A software program for performing level of
  service analyses for motorized (auto and bus) and
  non-motorized (bike and ped) modes of traffic on
  arterial streets.
• It was developed for the Florida Department of
  Transportation by the Transportation Research
  Center at the University of Florida, in
  conjunction with Polytechnic University (New
  York).
• The underlying analysis methodologies are based
  on HCM 2000 procedures, as well as other research
  conducted by various contractors on behalf of the
  Florida Department of Transportation.

Overview of ARTPLAN 2008

• ARTPLAN is intended to be used at the planning
  level of analysis
• Planning level analysis is characterized by the
  use of assumptions, approximations and default
  values to reduce the need for the detailed field
  data upon which operational level analyses are
  based. Procedures have been developed for
  application at two levels
• Generalized planning, which typically makes use
  of statewide service volume tables, and
• Conceptual planning, which applies user-specified
  parameter values. The conceptual planning level
  procedure includes features that estimate the
  level of service (LOS) for site-specific
  conditions and features that generate
  service-volume tables.

ARTPLAN ScreensMultimodal Data

• Segment Data (Multimodal)
• Used to specify multimodal information (e.g.,
  sidewalks, bike lanes, bus frequency) at the
  segment level.
• Pedestrian Subsegment Data
• Used to specify multimodal information at the
  subsegment level, such as when a sidewalk is not
  continuous for an entire segment .

Transitioning from Planning to Operations Analysis

• After inputting data into ARTPLAN, you can easily
  export it to TRANSYT-7F (T-7F)

13
Data Import Assumptions

• Because T-7F requires more input data than
  ARTPLAN, the missing data items must be filled in
  and added to the T-7F input data set
• This is initially done by assuming certain values
  for the missing data
• The user can later modify if necessary

14
Data Import Assumptions

• Phasing Scheme
• If the intersection has left-turn bays for the
  main street, four phases are assumed otherwise,
  two phases.
• Timing
• For a four-phase intersection, the cross-street
  left turns are given 1/3 of the total
  cross-street green time.
• Traffic Volumes
• Cross-street volumes are set at 20 of the volume
  of the corresponding major-street movement.
• Other
• Left turns from exclusive lanes are protected.
• Right turn bays are set at 200 ft long.

Overview of TRANSYT-7F

• TRAffic Network StudY Tool (Ver. 11.3)
• Two major functions
• Simulate
• Optimize
• Macroscopic Simulation
• Considers platoons (groups) of cars, rather than
  individual vehicles
• Multidirectional
• Considers cross streets in addition to major
  street

16
Overview of TRANSYT-7FRun Instructions

• When you first launch T-7F from ARTPLAN, you are
  taken to the Run Instructions window, where you
  can select between multiple options.
• Link Wise vs. Step Wise
• English vs. Metric Units
• Single vs. Multi Cycle
• Simulation vs. Optimization

17
Overview of TRANSYT-7FTime-Space Diagram

• The time-space diagram is one of many features
  available in T-7F. It is useful for evaluating
  progression quality.

18
Overview of TRANSYT-7FTime-Space Diagram

• The time-space diagram allows the user to specify
  a specific number of cycles for display (3 or 4
  is recommended).
• The user can also scroll the offset at each
  intersection to see the effect on progression
  quality.

19
Overview of TRANSYT-7FMap View

• The map view provides a plan view of the
  arterial. It allows for quick access to a
  multitude of settings and reports for individual
  intersections.

20
Overview of TRANSYT-7FMap View

• To access the various reports and settings for a
  specific intersection, right-click on an
  intersection (node) to obtain the menu options.

21
Overview of TRANSYT-7FHCS Analysis

• Map view can also be used to access the Highway
  Capacity Software .
• The appropriate data input items are
  automatically exported to HCS.
• HCS can be used to perform a signalized
  intersection analysis according to the HCM
  procedure.

22
Overview of TRANSYT-7FRun Report

• The TRANSYT-7F Run Report is a comprehensive,
  detailed report for all movements at each
  intersection and for the arterial as a whole.
• Traffic Flow Rate
• Saturation Flow Rate
• Degree of Saturation
• Delay
• Stops
• And more

23
Overview of TRANSYT-7FRun Report

• To view the T-7F Report, click on Run and then
  TRANSYT-7F.

24
TRAFVU Animation

• TRAFVU animation can be launched with the press
  of a single button from T-7F.
• After launching the TRAFVU Animation, an empty
  arterial will appear. To view the cars and the
  signal indications, click the two buttons in the
  top left corner. The zoom and pan controls are
  also on that toolbar.
