21. We will start the super elevation 100 feet

from the beginning of the road so enter

1+00

in the

Start Station

field.

22. The super elevation will be at the final

slope after 25 feet so enter

1+25

in the

(QG 6WDWLRQ field.

23. The start slope must be the same as the

slope of the first segment of the template
that leads into the super elevation, so
leave the

Slope 1

field set to -

24. We want the ending slope to be 8% so in the

Slope 2

field, enter

for simplicity, we will not use parabolic transitions so leave those
fields set to 0.

25. Most super elevations hinge at center so be sure the

Hinge on

field is toggled to

&HQWHU and then tap 2. to continue. This will

complete the super elevation for the beginning of the curve on the
left side of the road.

26. We now need to add a super elevation at the end of the curve on

the left side of the road to change the slope back to -2%.

27. With

selected in the

eft column, tap the

$GG« button

again.

28. From the Add Left Super Elevation screen we will start the

transition out of the super elevation 200 feet from the beginning
of the road so enter

2+00

in the

Start Station

field.

29. The super elevation will return to the original slope after 25 feet

so enter

2+25

in the

(QG 6WDWLRQ field.

30. The start slope must be the same as the slope of the road where it

leads into the super elevation, so leave the

Slope 1

field set to 8.

31. We want the ending slope to be -2% so in the

Slope 2

field, enter

-2

. Leave the parabolic transition fields set to 0.

32. Be sure the

Hinge on

field is toggled to

&HQWHU and then tap 2.

to continue. This will complete the super elevation entries for the
left side of the road.
