Super elevated planar sidewalk with intersection

Hi

 

Super elevated planar sidewalk with intersection

 

I am designing a sidewalk which is super elevated
with a normal lane width of 0.718 meter.

 

So thus the overall width is 1.436=2*0.718 m or imperial 56.5 inches.
In the calculate super for the sidewalk alignment i set the normal lane width
to 0.718m and normal lane slop at 0.00% and a walking speed of
50 Kmh or 31 mph to populate the super elevation table for this
class 1 sidewalk.

 

Note: Low side Pivot is on inside curve of sidewalk.

 

So i am having a difficult time getting the low side sidewalk to be
at elevation 99.00 O/S 0.718 from CL.

 

Under the sidewalk are standard specification hardwood timbers to support heavy groups of

random zealot protesting marchers  who are against against any kind of industry

that generates jobs. These large groups of zealots are every where here in Canada

and seem to emerge in protesting mode always after listening to CBC radio combined with

to much heavy caffeine tea.

 

Note at end of support timbers is the elevation 99.0 inside curve.

 

So those with planar road experience please comment on this website
and your responses will be treated with strictest confidence and ridicule

 

To aid in your scientific C3D cad analyses this super elevated sidewalk is sometimes called a "railway" 
do not let the term "railway" make this sidewalk seem complicated its not.

Figured it out planar roads need a lane "width" parameter

 

Note not all Stock subassemblys support a "Lane" ie have one,
for planar to work you have to have subassembly with a lane width
so C3D can use the "lanewidth" for planar roads.

 

So if building a planar road look to a 

SAC built see Subassembly.PKS_Right_Side_Rail_Complete

Note not all Stock subassembly support a "Lane" or have one
for planar to work you have to have subassembly with a lane width
so C3D can use the "lanewidth" for planar roads

So in SAC make a Parameter with Width much like
Subassembly.LaneSuperelevationAOR
which makes a nice planar road.

 

So in SAC make a Parameter with Width much like stock
Subassembly.LaneSuperelevationAOR
which makes a nice planar road because it has a lane "width"

 

Please review updated 2017 C3D Dwg note low rail position at 99.00 FG top rail

Are you using 2018? If so, forget about superelevation and use offset alignments and dynamic offset profiles.  Much simpler to control

 

see my AU class Dynamic Offset Profile,  not railways but you’ll get the idea

Hi

Thanks for the lead

 

I will give it a watch

using 2017 right now

could install 2018

and give it a shot at the railway   superelevated sidewalk

 

Regards

 

Pete
