Cabintaxi network simulation results for a portion of the City of Hamburg, Germany

---

The Cabintaxi system implementation program for Hamburg was the largest
implementation effort in history, for the introduction of demand responsive
urban transportation technology into a real city environment.  Working with
a complete, successfully developed technology, where all aspects of the
system were known, the project planning went ahead from 1976 through 1979.
The implementation project for Hamburg began as a comprehensive feasibility
and alternatives analysis, and, after the Cabintaxi technology demonstrated
its superiority over conventional technologies, the program completed the
detailed planning and final systems engineering phase before the project was
stopped just prior to installation.  The project was stopped for budgetary
reasons within the federal funding agency. 

Two maps of simulation work done in conjunction with this project are shown
below.  They shows the expected operational performance of the two-way,
(over-and-under) single guideway Cabintaxi network in terms of boardings at
various stations and their associated peak flows in each segment of the network
 for the three passenger vehicle version of the technology.  If one enlarges the
network map to see the block level, and compares it with other application
proposals of single level small vehicle systems, the reduced level of structural
and visual intrusion can be graphically seen. 
 
The Hamburg study was a full-scale feasibility, alternatives analysis, and
implementation program, done in cooperation with a major transit property.
It included real-world traffic generation, distribution, assignment and mode
split analysis.  The studies analyzed a large portion of the northern
section of the City of Hamburg.  Once the determination was made to move
forward with the installation, the project was broken into a phased
development.

The 3-passenger vehicle maps show a 30-mile network with 73 stations. They
provide an example of the scope and detailed analyses that were produced in
these German studies. They also provide a perspective on the expectations
held by some for the deployment of Cabintaxi in German cities in the late
70's. Their graphic clarity is also noteworthy.
