How CMT Works


Existing Service Has Problems
•    Too Slow : 22 miles from East Oltorf to Lakeline Mall takes  2 hrs 40 min.
•    Long Waits: On most routes the wait between buses is 30+ minutes.
•    Poor Transfer Conditions : Lack of shelter, Air Conditioning, security, or real time info at transfer points


A 22 mile trip with conventional bus service takes too long.
Starting on east Oltorf and going to Lakeline Mall takes about 160 minutes.
Some of the time is for walking , waiting and transferring.
About two hours, or 120 minutes is spent riding buses that lumber along at 11 mph.
They are slow because they are stopping ten times a mile to pickup and drop off riders.
Transfers are required. Some transfers will take 30 minutes at an unsheltered stop.
You could be standing in the August sun or winter wind for 30 minutes waiting for the next bus. 


How conventional
      works



 CMT Service would be faster. Some trips would take half the time.

Travel time is reduced from 160 minutes to 80.
Example trip has 3 legs:   First 2 miles by feeder van, then 18 miles by express bus, and last 2 miles by van.  
Express Bus is fast because it runs on road with signal control and queue jumpers.

Red dots are Transit centers with air conditioning where riders transfer from feeder to express.

CMT  would be Cellular


Feeder Routes converge on each Transit Center.
Feeder Routes (thin black lines) stop 5 times per mile and average 15 mph.
Express Routes (thick green line) would run 3 to 15 miles between stops at Transit Centers (TCs) and average 30 to 50 mph. 
Express  bus would use HOT lanes, toll roads or streets with queue jumpers


The express bus takes
riders from a home cell
out to work cell. 


At work cell TC there
 would be six feeder
 routes that fan out to
 reach hundreds of
employers scattered
over a low density cell.


Vans would depart
every 5 to 12
minutes with CMT.


Current system has
 feeder routes with
30 minutes or more
between bus runs.

Although most feeder trips would be run by taxi-vans, these vans are running fixed routes.
They would NOT drop you off at your front door.
But vans would run within a half mile of every home and job site every 5-12 minutes for 16 hours a day.

Transfer from Feeder to Express

Yellow Vans bring riders from surrounding neighborhoods to the local transit center.
Riders board Blue Express Bus for trips to distant transit centers.
Fares are collected electronically as riders enter gates over 3 minute period.
Twenty riders board in under 30 seconds, when bus arrives, because they have already paid fare.
It would be like riders boarding a subway.

Demand Responsive Service at the Work Cell Transit Center


Riders Line Up at Feeder Route Markers

These six feeder routes will fan out to reach all employers in a cell of 12 square miles.
A line of vans and buses wait nearby with no pre - assigned route. Vans are sent to take small groups.   
Mini-buses take larger groups. 
Wait time averages 5 minutes.     Maximum Wait time is 12 minutes.

Why Use Vans ?
Demand responsive service, with vans, is the more economical way to connect a transit center
to the  hundreds of employers scattered over a 12 square mile cell.
Most jobs (70-80%) in Austin are in low density areas.
Computer modeling predicts that most feeder trips in low density areas will have 14 or fewer riders.
It is cheaper to take 14 riders by van than by 45 seat bus.  .

Vans are better for feeder ( or circulator) trips
 during off peak hours.

A three mile feeder trip in the off peak hours will have eight or fewer riders when it leaves the TC.
The average number of riders on board would be only 4 over all miles traveled.

If we compare bus with van for this type of trip, they both will carry an average of four riders, and do 15 mph. They will both collect $21 in fares per hour.

But the bus costs a lot more, $115 per compared to only $44 for the van.

The fares collected, $21, takes a much bigger bite out of the van cost. So subsidy per hour is $94 for the bus but only $23 for the van.

The van would be FOUR times cheaper.

The hourly rates , $115 & $44, include administrative overhead. If we look at just direct costs, like maintenance, insurance, labor and fuel, the costs would be closer to $79 for bus and $32 for van.

If we compare with direct costs the subsidy per bus mile is $3.87 and only $0.73 per van mile.

The van would be FIVE times cheaper.
