Common Parameters and Unknown Control Type

Every intersection setup table includes common parameters, including the intersection number, name, control type, approach name, approach direction, turning movement, base volume input, and the total analysis volume (see section Intersection Setup: Unknown Control Type Common Parameters Table). Once the control type and methodology are defined, the parameters relevant to that combination are displayed. The common parameters displayed below are also the default attributes for the Unknown control type definition (see section Intersection Setup: Common Intersection Setup Parameters).

Parameter Description Units

Number

Unique number of the intersection. Intersections are numbered consecutively. However the preset number may be overwritten by another number that does not already exist in the network.

n/a

Intersection

Name of Intersection

n/a

Control Type

Intersection control type:

  • Unknown
  • Uncontrolled
  • Signalized
  • Roundabout
  • All-way stop
  • Two-way stop
  • Two-way yield

n/a

Name

Name of Approach

n/a

Show Name

If checked, the text entered in the Name field will be shown in the network window when the Show Street Names graphics selector is active.

n/a

Approach

Direction of Approach. Eight approaches possible [NB, SB, EB, WB, NW, NE, SW, SE]

n/a

Lane Configuration

Graphical selector and representation of the lane configuration for each approach described below

n/a

Turning Movement

Direction of turning movement. When there are more than 4 legs it is possible to have more than one left or right turn for a particular movement. In this case the adjacent turn movement will be appended with the number 2. For example, an approach to 5 other legs may show Left2, Left, Thru, Right, Right2.

n/a

Base Volume Input

Base traffic volume input by user. Base volume may be entered in either the intersection setup table or the volume table.

Veh/h

Total Analysis Volume

Calculated total analysis volume. The total analysis volume includes all volume adjustments defined and site development trips if present (see section(see section Volumes) for a detailed description of volume parameters).

Veh/h

Crosswalk

Crosswalk selection for approach

n/a
