Description / Abstract:
Design criteria specifically recognize the unique features of
concrete transit guideways—namely, guideway/vehicle interaction,
rail/structure interaction, special fatigue requirements, and
aesthetic requirements in urban areas. Criteria are based on
current state-of-the-art practice for moderatespeed (up to 100 mph
[160 km/h]) vehicles. Application of these criteria for advanced
technologies other than those discussed in this guide requires an
independent assessment.
AASHTO LRFD Bridge Design Specifications (AASHTO 2012) and ACI
343R are referenced for specific items not covered in these
recommendations, including materials, construction considerations,
and segmental construction.
