It is unclear (to me) whether the access is "Right in" to the destination, or "Right in" to the cul from the traffic generator.
What is volume of traffic in cul and in access leg?
What is purpose of changing T intersection to cul? Is there a large U-turn component? Is...
If thye upkeep of round a bouts makes them unpopular, but some traffic calming devices are needed to prevent rat race speeding, why not make use of the wider ROW at the two now joined cul bulbs. create a chicane by jogging the alignment first from one side of the wider ROW to the other side...
As an aside, many towns have an ordinance written in years ago, promoted by the fire Department, PROHIBITING the construction of any kind of bumps in the roadway. Legal opinion was that althought this was written in the days of speed bumps, it also includes humps.

How far is the road to be extended?
What is the new end condition to be vis a vis u-turns?
Who maintains the island?
Can fire trucks get past it easily?
What is the ROW situation? Quite often the cul reaches the end line with the circle tangent to the end line at one point only. That means land...
The low clearance (4") is what was giving me the problem. I have found non-concrete ones that look good. The "Concrete" criteria was the facility's original choice. I seem to have convinced them to come into the 21ST century
Thanx all for your assistance.
Take a careful look at the Municipal Ordinance. You may not be able to do what you want to do. Many communities have ordinances passed years ago, at the "suggestion" of fire departments, that preclude building any bump or hump in the roadway. Educating the fire dept and the Council is...
I have a copy of a Oct 2002 e-mail from Dave Bizuga of NJDOT (sent to me by COTE-L) re NJDOT's experience with Safti-Trax made by COTE-L Industries (201-836 0733) stating that a 2002 survey of 139 curb ramps detectable warning surfaces, placed in 1995, showed 49% were 90 to 100% intact and...
Many culs have lolly pop alignment. That is the cul is centered on the incoming roadway. The criteria seems to be the ability of the developer to get a reasonable lot layout.
Once the roadway is located make sure the radii are sufficient going in and out. Sometimes a central landscape island is...

Several things come into consideration.
1 Are there existing sidewalks nearby? Would this be a gap?
2 On a cul, will school buses enter the cul or will kids have to walk to the main street?
3. Where is school, playground, ball fields? In walking distance?
4. Are there many/any peds on heavy thru...
We find the best flow of traffic occurs when the cul is tangent to the right (incoming)side of the road. In other cases we increase the radius of the curb return where the cul bulb meets the roadway, to provide better flow. The radius depends on the alignment of the road and bulb. Throw a curve...
