PC Miler: Calculate ETA

Calculate ETA/ETD With Time‐Based Routing & Traffic Data

 PC*MILER’s time‐based routing offers more precise travel time estimates, taking into consideration the time of day, day of the week, and time zones in route calculation and reports.   Optionally, real‐time and historical traffic data can also be used in route calculations for even more accuracy (a subscription to PC*MILER|Traffic and an Internet connection is required).

In this stop on the Tour, we will enter a target arrival time and calculate the necessary departure time at the origin and arrival times at two intermediate stops.

1.  Click the New Route toolbar button to open a new route window (Route 4).

2.  In the Depart/Arrive drop‐down list above “Use Traffic Data”, click the arrow and choose Arrive.

3.  The button to the right of the drop‐down determines whether a day of the week or the current date displays to the right.  We will use a day of the week to calculate this route (this is the default setting).

4.  In the Day of Week drop‐down list, click the arrow and choose Tuesday.

5.  In the Local stop time list, set the time to 4:30 PM: first click the hour to highlight it, then type or use the up/down arrows to set it to “04”; next, click the minutes setting and set it to “30”; then click the AM/PM setting and set it to “PM”.

6.  If your copy of PC*MILER includes a subscription to PC*MILER|Traffic, uncheck Use Traffic Data (we’ll get back to it in a minute).   The route window is now ready to calculate a route that arrives at its final destination on a Tuesday at 4:30 PM:

Calculate ETA

NOTE:  Both the time format (24 hours vs. AM/PM) and the time zone that is used for reporting can be changed in the Tools menu.  The time zone does not affect calculations.

7.  Now let’s enter an  origin,  destination,  and  stops  on  this  route.    Enter the following locations in this order: Elizabeth, NJHamilton, NJCamden, NJ; and Pittsburgh, PA using any ZIP codes.  (We won’t use addresses in this example to keep it simple.)

8.  Click Run or press the <F10> key to generate the route.  In the ETA/ETD column you can see that this truck would have to depart Elizabeth at approximately 10:00 to get to Pittsburgh at 4:30.  We didn’t set the amount of time spent at each  stop  or  any  break  time  in  the  Options  dialog  box  (see  p.  31‐32  for time/cost editing), so this is a reflection of just the driving time.

9.  (If PC*MILER|Traffic and an Internet connection is not available, skip to Step 10.)   Now we’ll make one change to this route: click the Use Traffic Data button.  The route will recalculate using real time and recent historical traffic pattern data, at the specified time, on the specified day of the week.   Using traffic data, the estimated time of departure at the origin is approximately 40 minutes earlier for this route.*

10. We won’t be using this route again, so close Route 4 by clicking on the “X” in the upper right corner of the route window to continue the Tour.* Up to and including Version 26, PC*MILER default routes, distances and travel times are calculated based on average road speeds by state/province, urban/rural, and class of road. Using traffic data can further enhance the accuracy of driving time estimates.
