TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.

This ground-breaking book explores a rapidly developing aspect of contemporary life: automated and autonomous spatial mobilities and their social and urban implications. Presenting a wide-ranging discussion on autonomous vehicle (AV) development and its future adoption, this highly topical book points to the emergence of autonomously mobile cities and the new mobility landscapes they will present. Academics, as well as practitioners, in the fields of mobility, transportation, urban planning, geography and sociology will find this an essential read.
