Off-Line Station Train Control Functional Requirements Martin Lowson Presentation at 2013 APM Conference:
“I feel that the Ultra design has been better because of our utilization of the APM standards. I have also found that the committee is prepared to be respond effectively to issues bought to their attention. An example is off-line stations, which are a feature of PRT systems, but are not a feature in conventional APMs .”

TECHNICAL PAPER AT 2005 APM CONFERENCE:
OPTIMIZING AGT APPLICATIONS THROUGH DEMAND-RESPONSIVE CONTROL SYSTEMS
J. Sam Lott Kimley-Horn and Associates, Inc.
Eugene Nishinaga Bay Area Rapid Transit District
What’s the Point?
Premise: Supervisory Control Systems with demand-responsive capability, when combined with a hybrid operation of direct station to station dispatch and conventional service, allow more cost effective systems to be built and operated, while providing passengers with a higher level of service.
Benefits of the Hybrid Approach
•
Off-line stations allow more frequent passage of smaller, independent vehicles on the main line
•
Smaller vehicles lower the civil construction cost through reduced size of guideway/stations
Benefits of the Hybrid Approach (cont.)
•
Hybrid operations provide service levels competitive with conventional mass transit
•
Direct-to-destination service reduces passenger travel time and reduces empty vehicle (non-revenue) seat-miles
•
Flexibility of hybrid operations allows efficiency to be optimized between demand responsive and conventional modes
Conclusions
•
Hybrid Operations have the potential to reduce vehicle size and associated costs, increase revenue per seat-mile, and improve passenger service by the combination of:
Demand Responsive/Direct to Destination Operations
Conventional Fixed Route Operations
•
Hybrid Operations could radically change our concept of what constitutes high-capacity transit

Task Force Formed Under WG 39 and 45 to Develop an International Consensus on:
• Hazards of Fully Automated DTO and UTO Operations • Appropriate Functional Safeguards to Mitigate Hazards •
Series of Meetings Built Progressive Consensus:
• Format and Terminology • Hazard Identification and Categorization • Generic Safeguards to Mitigate Hazards •
IEC Technical Report Established a Framework for Generic Hazard Analysis of AUGT/APM Design
•
Full Risk Analysis Still Required for Each Project

Alain’s Instructions
• •
Alain’s Initial Invitation August 22 nd and September 5 th Any chance that you could come over to Washington in October and speak in my session at the Podcar Conference . A followup to your presentation and comments at Stanford would be ideal for this conference.
•
Also, you might be able to comment on ASCE's APM Standards and how they may help/hinder the evolution of driverless cars as a shared-ride "transit" option.
•
I'm trying to put together a session that bridge the advances in vehicle automation (those advances that lead to the ability to remove the driver from the vehicle and have it operate in mixed (with conventional cars & trucks) traffic on existing streets and highways ) with the provision of shared-ride "transit"(a fleet of vehicles owned and operated by some entity(ies) that offer mobility to the general public.)
•
Here was a thought I had: "Evolving APMs to ATNs using Driverless car technology" with some emphasis on the "Standards" especially given ASCE's APM Standards My final response on September Okay, I can run with this topic. It actually ties into a technical paper I did with Gene Nishinaga for the 2005 APM Conference. It was called “Optimizing AGT Applications Through Demand-Responsive Control Systems”. I will use this specific topic that you have recommended, with a minor change to the title if possible – “The Evolution of APM Systems to ATN Systems Using Driverless Car Technology”.
