How would you create turtles on a patch with a given speed and heading?

I tried using sprout to generate patches on a specific patch, but after looking in the Netlogo dictionary I found that this command creates turtles with random speeds and titles. Likewise, (crt) only creates the turtles at the origin, and I believe that by specifying the coordinates, you can distinguish where the turtles were born. The problem with both of these options is that they limit the ability of users to create and test road networks for themselves in the UI, and I am looking for a command or piece of code that will allow me to create turtles with given headers and speeds to set a patch of a specific color. Here's some sample code I'm using:

   globals[road? ]
   turtles-own [speed]
       breed[cars car]
     breed [sinks sink]
   to setup
  clear-all
  ask patches [set pcolor green ]
  set-patch-size 50
  if mouse-down?
 [ ask patch mouse-xcor mouse-ycor [ edit-world-primary ]
 ] 

 end
   to go
 if mouse-down?
 [ ask patch mouse-xcor mouse-ycor [ edit-world-primary ]
  ] 
 edit-world-secondary
ask turtles-on patches with[pcolor = blue][set heading 90 ]
ask patches [if pcolor = blue [sprout 2 ] ]
 ask turtles[   
 set shape"car"
 set color white
 set speed 90]
 ask turtles[ rt 0 fd speed set heading 90 ]

 end

Any help on changing the commands I use in my code is greatly appreciated.

Ask patches with[pcolor = blue ][sprout 5 [set heading 90 set velocity .1]]

There are all the parts you seem to be looking for.

To make the turtles move with speed.



To go
   Ask turtles [fd velocity]
End

Install this permanently and your turtles will be silent.

Check out the command sprout

for creating turtles on specific patches.



You can also move-to

create a specific turtle or patch. This can be useful if your roads are made of nodes (turtles) and links.
