Conference Paper
A study was recently undertaken for a client in the Silicon Valley to explore the capacity limits of automated transit networks based on small vehicles departing on demand. Based on proven PRT designs, advanced strategies were developed for ridesharing with multiple destinations and multiple origins. These strategies were applied to morning (few to...

Disclosed is a method of increasing track capacity in an automated vehicle system, the automated vehicle system comprising a network of tracks along which vehicles are adapted to travel, the network comprising at least one merge point at which at least two up stream tracks merge to form a downstream track, at least one diverge point at which one up...
Conference Paper
Personal Rapid Transit (PRT) is a mode designed to increase the service level of public transport so as to approach that of taxi and private cars. The PRT systems in public service today are stand-alone systems within confined areas with no other public transportation. This paper describes potential applications where PRT is an integrated part of p...
Conference Paper
Full-text available
Cost issues have been an important concern in the development of Personal Rapid Transit (PRT) since the concept was developed several decades ago. The lightweight, computer-guided electric vehicles operating the PRT system are generally a major part of the capital cost of the system, especially in larger network with high demand. A sufficient numbe...
Article
Point-synchronous control for large personal rapid transit (PRT) systems that offers a possibility of increasing the link capacity for empty vehicles is described. Two different principles for the redistribution of empty vehicles are outlined. Depots for empty vehicles are introduced so that the passenger stations can be kept smaller. The methods w...
Article
Projektet test av dynamiska trafiksimuleringsmodeller (DYMO) initierades av Björn Hugosson, Transek mot bakgrund av de erfarenheter som erhölls i samband med den strategiska utvärderingen av väginformatik i TOSCA-projektet och den tillhörande modellinventeringen. Det framgick därvid att mer ingående studier av aktuella modellverktyg var önskvärda.
