Automated transit and land use intentions: Alternate scenarios with PRT and shuttle/loop technologies

Abstract

Abstract Ecological impacts of urban sprawl on the land, as well as forces that engender sprawl are outlined. Long‐range land use priorities for more compact, transit‐oriented development (TOD) are seen as ecological imperatives. While Personal Rapid Transit (PRT) could solve some congestion, it does not address these priorities. Several assumptions that underlie the PRT concept, particularly the premise that denser land use is per se socially undesirable, are challenged in terms of historical precedent. Rather, the explosive scale of ubiquitous motoring is seen as the key component of today's resistance to dense development. With peripheral parking and medium‐capacity AGT links to regional transportation networks, new TOD could be redefined as pedestrian‐zoned and richly landscaped urban neighborhoods; this would help resolve essential traffic and environmental barriers to its realization. The simpler automated shuttle and loop technologies are seen as more compact and potentially affordable for this purpose. Steps that could help open the way toward realization of such development are discussed.
