Cobb transit should be elevated, not on ground

DEAR EDITOR:

Get Cobb transit off the ground. Any ground-based transit system (bus, bus rapid transit, etc.) will hinder functions along U.S. 41 and the other roads in the “Connect Cobb” plan.

Cars on crossroads have to stop for transit vehicles at intersections, ruining synchronized traffic signal timing.

If transit runs in the middle of the road, cars have to do a “U” turn at the next corner, and return the other way to get to a store. U turns are slow, and the return trip to the store increases congestion in the returning lane.

A dedicated transit lane on the side of the highway blocks every private and commercial driveway it passes.

Ground-level transit slows the functions of a road, no matter where you put it.

An overhead system jumps across roads. It runs behind homes and businesses rather than in front yards. It can jump I-285. It flies across bike paths and sidewalks. It will really help relieve traffic congestion.

An overhead system condemns much less land. With a small base for the columns, the rest of the land under the elevated guideway continues to be useful. Land acquisition costs go down.

Cobb CCT and DOT know about equipment that will do the job. Disney World has had an elevated system for years.

I question transit cost effectiveness, but a system on the ground surely will make things worse. Cobb needs to get transit off the ground.

I guess you've never seen DART in Dallas in person. There's many ways to have ground-based service that don't hinder operations. The queue-jumping is built into signal timing for synchronization. And trains come infrequently. There isn't a steady stream of them. Raised track is expensive. Tunneled track is expensive. It also doesn't integrate as well with pedestrian traffic. There's no way to just hop on a train for either, go a few blocks, then hop off without going up or down stairs. What you are talking about is more of a commuter system, or express line. That isn't going to bring people into the doors of local businesses.

Look at how Dallas's DART transit system works inside the beltway in Dallas. I had the pleasure of riding it over the weekend while visiting Dallas. It's pretty amazing. I've also been on similar "trams" in Europe, though older, integrate pretty well with the street system.

Just like for DART, elevated guide-ways or tunneling will probably be used in areas where it's necessary. But it isn't necessary everywhere.

This is a good letter with a perspective that cannot be ignored. I'm surprised there have been no comments.
why not

It's because an intelligent opinion in the MDJ is so rare, many people are still in shock!
