They want the guys to manually go through mapbooks and figure mileage, hours, etc. Any easy formula?

Not exactly sure which formula you're looking for but I'll give this a shot.

300 miles at 60 mph is going to take 5 hours, if you don't make any stops. Any time you have the word "per" in there, it's going to be a division problem, as in

300 miles / 60mph = 5 hours

If you're looking at how much fuel will be required ...If you're traveling that same 300 miles and you are getting 7 miles per gallon, take those 300 miles and divide by 7 ...so

300mi / 7 mpg = 42.86 gals to make that trip

If you want to know the cost of that trip for the company, in fuel, take those 42.86 gals and multiply it by the price of the fuel ...

42.86gals x $3.70per gal = $180.78 for that 300 mile trip

Just to recap the above:

...# miles / # miles per hour = #hrs

...# miles / # miles per gal = # gals

...# gals x # $ per gal = # $ to pay for the trip

I'm no expert on trip planning but I hope this helps.

Well you will know the mileage cause that comes with each load assignment. Take the mileage and devide it by 55 mph and that's roughly how long the trip will take. You can't use the actual speed limit cause there are a lot of variables that will lower your average speed for the truck.

Trip planning is a rough guesstimate on how long the trip will last and when you will arrive at your location.

One 40 mph construction zone will wreck your 300*60=5 hour formula. In order to make that in 5 hours you will have set set you cruise at 60 and never tap the brakes.

Now tell me, remember it's summer, where you can run for 300 miles and not be slowed down by construction?

Being O/O's, we trip planned at 45 mph...why ?? well, it took in fueling, construction, congestion, and meals, if they were speedy. And...it gave us wiggle room for flat tires, reefer crap, and general Murphy's Law stuff. It kept us on time, usually early, and we never felt pushed. Unfortunately, as company drivers, you don't have that luxury.....

I use a 50 mph rule because its easy. Thats 2 hrs for every 100 miles. So, 800 miles = 16 hrs. I add an hour to that to cover my 30 min 'lunch break' and 2 bio breaks, plus an additional 30 mins for each fuel stop. Finally, if Im loaded heavy and going through the east coast mtns, I add another hour. Then I back track the time to allow me to arrive 2 hrs early and allot for any 10 hr breaks.

I know if I can drive all day, I can do 600 miles on flat surfaces, and around 550 miles on rolling terrain.

It works for me.

Truckersgirl53, what are they trying to accomplish with this? I mean, is this an exercise for the drivers to get better at trip planning or is this something for the logistics department or something?

Because there has been software around forever that can do that stuff. Nothing of the sort has to be done manually. So let us know the purpose of the exercise and we can give you more accurate advice.
