If remember this it was written by a big Australian consulting engineers as per date 1995 Maunsell & partners, so I am not going to touch their code as it was probably "it has exited the building and we did not know". 

 

There is also single line chevrons plus I think some more, need to get my VIC Roads hand book out and look at line marking.

Ok been a while and no longer have access to the road marking standards, your question is very much a "gone down the rabbit hole" there are so many constraints when it comes to doing chevrons, you have shown possibly the simplest shape. 

 

Did you find any government  standards ? It gets very complex depending on scenario, look at left slip lane. 

 

You need to provide working samples and explain the spacings widths and angles. As I said you provided the simplest shape which probably does not occur in real world roads. I know what I did took into account curved sides.

Sir, code is working perfectly for me and as per my requirement also.

 

Only missing that 2 point,

 

Starting interval and continuous interval.

 

Rest is ok.

 

What I draw above it came from this lisp.

 

Thanks

Can you post some sample of chevron shapes, I know can be single solid left or right and a "V" as per image, the enclosing shape is the issue.
