摘要：	The report consists of 20 papers that examine weathered steel beam guardrails; longitudinal barriers struck by large trucks; continuous speed profile models for two-lane rural roads; integrating context-sensitive solutions into designbuild programs; characterization of stormwater runoff; comparison of crash test and simulation results for New Jersey barriers; and design guidance for freeway main-line ramp terminals. This issue of the TRR also explores geometric design, speed, and safety; unconventional geometric design; canal wave oscillations; reducing turbidity of construction site runoff; field application and assessment of the safety edge; single-vehicle roadway departure crashes on rural two-lane roads; spacing of entranceexit ramp sequences; freeway acceleration speed-change lanes; simplified midwest guardrail system stiffness transition; universal breakaway steel post for bullnose median barrier; low-cost median barrier gate; utility investigation trends in Texas; and minimum rail height and design impact load for longitudinal barriers.
