Testing Trip Combinations

Test trip combinations within the Blocked or Unblocked trips grids with the Test Hook dialog box.

Note: The results of the test depend on the properties you set for Min/Max Layover and Min/Max Deadhead.
  1. Click Blocking > Test Hook.
    The Test Hook dialog box appears.
    Test Hook dialog box
  2. From either grid on the Blocking tab, select the trip you want to test.
  3. In the Test Hook dialog box, click Get Trip 1.
    The selected trip from the Unblocked grid appears in the dialog box.
  4. From either grid on the Blocking tab, select another trip to which you want to link or hook Trip 1.
  5. Click Get Trip 2.
    The second trip appears in the grid under Trip 1.
  6. Click Test Hook.
    A statement appears in the Status field advising you if the combination works. If the trips can possibly hook together, the statement, "Hook allowed" appears. If the combination is invalid, an error message appears such as "Invalid max layover." See the example discussed for an illustration of this message.
  7. Click OK.
To illustrate the sample error message in step 6, consider a trip combination in which the layover exceeds the value set for Max layover in the Blocking parameters. The Max Layover property needs to be increased to achieve a positive result. If you set the Max LO to 20 minutes and hooking the trips means a layover of 30 minutes, an error message appears. If allowable within the policies and union agreements of your transit site, change the Max LO value in the Blocking Parameters dialog box to 30 and try to hook the trips again. The hooking should be allowed.
