CHART OF TRAVEL AND DELIVERY TIMES OF VEHICLES TESTED AT MIAMI, FLA.,

DURING CALENDAR YEAR 1954 The attached bar graph shows the simulated route time required by vehicles tested to effect delivery of 122 mixed letters and 36 pieces of flat mail to 100 curb-line boxes erected 45 inches from the ground at 75-, 150-, and 300-foot intervals on the 1,875-foot perimeter of a rectangular roadway, smooth surfaced with crushed coral rock and isolated from traffic.

The first, second and third bars for each vehicle show the travel and stationary time involved in the delivery of mixed letter and flat mail to boxes spaced at 75-, 150-, and 300-foot intervals, respectively. The fourth bar, in each group shows the travel and stationary time involved in the delivery of a parcel (to the curb line) at 75-foot intervals.

Blue colors indicate time in motion; red indicates stationary time involved in making deliveries to 100-curb line boxes. Yellow indicates stationary time involved in making 100 parcel deliveries to points at the curb line.

The times shown are the averages of the normal performances of 3 operators for not less than 300 separately timed motion and stationary sequences for each of four different distances and types of test, except when breakdowns or other reasons made testing to this extent impracticable.

PROJECT RD-153, SUPPLEMENT No. 3-PROCEDURES AT MIAMI
Testing procedure was finally resolved to the following:
Twenty-five consecutively numbered rural mail boxes (No. 2 size) on movable,
adjustable height supports, were erected 45 inches from the ground at 75-foot

intervals on the 1,875-foot perimeter of a rectangular roadway surfaced with crushed coral rock and isolated from traffic.

One hundred and twenty-two mixed letters and 36 pieces of flat mail were addressed as follows and 50 deliveries made to the boxes indicated :

At 75-foot intervalsTravel begun at bow No. 25, 2 complete circuits made

[blocks in formation]

Simulated parcels were prepared and 50 deliveries made to the base of boxes at 75-foot intervals. The parcels approximated one-third cubic foot volume and were arranged on the floor or on shelves of the vehicle in a realistic manner in order of delivery. Delivery consisted of obtaining a parcel, dismounting from the vehicle, depositing the parcel on the ground and reentering the vehicle.

The time required to travel between stops, and the stationary time between intervals of travel, were recorded to the closest hundredths of a minute on forms prepared for this purpose. The timing was continuous with a decimal system watch. Stationary time included operations necessary to put vehicles in motion.
