| 摘要： | This document consists of 17 papers that explores railway infrastructure pricing in Europe for high-speed and intercity services; high-speed rail and air transportation intermodal passenger network design optimization; bicycle network connectivity for passenger rail stations; railway train wheel maintenance; and freight shipment demand in congested rail networks.This issue also examines deadlock avoidance and detection in railway simulation systems; capacity expansion strategies for single-track railway lines with sparse sidings; capacity charges for shared-use rail lines; siding location for single-track lines; load characterization techniques and an overview of the loading environment in North America; and a three-dimensional train-track-soil model for high-speed rail.Additionally, this TRR explores the influence of size and shape properties of railroad ballast on aggregate packing; railroad track transitions with multidepth deflectometers and strain gauges; slab upwarping of twin-block slab track on subgrade-bridge transition sections; ways to detect range-based rail gages and missing rail fasteners; track ballast fouling and permeability characterization by using resistivity; and ballast degradation through Los Angeles using abrasion tests and image analyses. |
