This program is used to compute a cross slope, vertical difference, and grade of a station that falls within a transition between a typical cross section and a superelevated cross section. The program will use a gradeline in the GRADE program to compute the grade, the cross slope and vertical difference will be computed by the SETRAN1 program. In order for this to work, SETRAN1 and SETRAN2 need to be loaded into the Party Chief unit. The program SETRAN1 needs to be loaded or defined in the USER KEYS menu, it will not cause any problems if both are loaded into this menu but the SETRAN1 will be the actual interface to the program. If you load SETRAN2 first then load SETRAN1 on the same key, only the program needed to the user will show up. Loading the programs is covered under User Keys Menu in the Party Chief manual (page 30 for Version 4.1). The following is an example based on the gradeline example from the Party Chief manual (page 89 for Version 4.1).

Step 1 (GRADE)

• Enter the grade program.
• [1] Boot a Curve (We will use a vertical curve in this example but it could be a straight grade)
• Fill in the data as shown here using the (letter K) and (letter Q) arrows. After all the data is entered press the softkey and review the PVC, PVI, and PVT data to verify correct data entry then press Any Key to continue.
  
• The next step is to enter Gradeline Limits. For this example you can enter 125 for Beg: (beginning of transition) and 210 for End: (end of transition) limits then press the softkey.
  
• Now press the softkey to exit the Grade program.

Step 2 (SETRAN1)

• [SETRAN1 User Key] Press the user key that the SETRAN1 program was loaded on, if you don't know which key this is press [USER KEYS] to see which key it was loaded on, and select the appropriate key.
  This program utilizes dialog boxes which use the up and down arrows for input as the GRADE program above.
• Enter the station you want to compute.
  Station: 150.00 Enter 150 (1+50.00) for the first station we want to compute.
  Horz OS: 0.00 This is the horizontal offset from PGL to the hinge point, in this case 0.
  Vert OS: 0.00 This is the vertical offset from PGL to the hinge point, in this case 0.
  S/O OS: 0.00 Unneeded since we are computing vertical only, used when using STAKE.
  Sta Inc: 25.00 Station Increment will be 25.00 feet.
  After all the data is entered press the softkey
  
• Enter Super elevation transition data.
  Beg Sta: 125.00 Beginning station of the transition.
  C.Slope: -2.00 Beginning cross slope of the transition.
  End Sta: 210.00 Ending station off the transition.
  C.Slope: 6.00 Ending cross slope of the transition.
  Hor.O/S: 12.00 Offset at which the grade is to be computed as in half of a 24.00 foot roadway.
  After all the data is entered press the softkey
  
• The program can now use the station up, station down, and station softkeys to solve for new stations.
  To change the transition values simply press the [SETRAN1 User Key] again to start over.
