罗利Glenwood South安全试点11月安装转向缓冲楔：随后进入6个月观察期
美国北卡罗来纳州韦克县罗利市交通部门宣布，该市Glenwood South街区安全试点将于2026年11月开始在Glenwood大道各路口安装转向缓冲楔，以降低车辆转弯速度、保护行人；缓冲楔装好后，试点第一阶段将进入为期6个月的观察期，并开放线上问卷收集社区反馈。
这项试点源于2025年1月的社区调查：750多名参与者中，超过90%表示在Glenwood South以步行方式出行，步行是该街区最主要的出行方式；呼声最高的改进包括抬高式人行横道与抬高式路口、提高行人可见度、降低车速。
转向缓冲楔是可供车辆碾压的橡胶楔体，黑白相间并带反光标识，钻入路面固定。它能收紧普通车辆的转弯半径、迫使驾驶人减速，同时不妨碍大型卡车转弯。据市政府介绍，这是罗利首次采用这类交通静稳设施。
此前在2025年11月，市政府曾在涂漆路缘扩展区试装柔性隔离柱，但一个月内大多数隔离柱被撞坏、移位或丢失，因此改用更耐用的缓冲楔。试点第一阶段还包括各路口的涂漆路缘扩展，预计2026年秋季完成；第二阶段将研究在各路口西侧修建抬高式人行横道。停车方面，除Glenwood大道与西诺斯街东南角的装卸区取消、塔克街代客装卸区东移20英尺外，基本不受影响。
Raleigh to Install Turn-Calming Wedges in Glenwood South This November, Followed by Six-Month Observation
In Raleigh, Wake County, North Carolina, the city's transportation department announced that its Glenwood South Safety Pilot will begin installing turn-calming wedges at intersections along Glenwood Avenue in November 2026 to slow turning vehicles and protect pedestrians. Once the wedges are in, Phase 1 of the pilot enters a six-month observation period, with an online survey to collect community feedback.
The pilot grew out of a January 2025 community survey: of more than 750 participants, over 90 percent said they walk while in Glenwood South, making walking the district's top travel mode. The highest-ranked improvements were hardscape measures such as raised crosswalks and raised intersections, along with better pedestrian visibility and lower vehicle speeds.
Turn-calming wedges are mountable rubber wedges with a black-and-white pattern and reflectors, drilled into the roadway. They tighten the turning radius for standard vehicles, forcing drivers to slow down, while still allowing large trucks to complete turns. The city says the treatment is new to Raleigh.
In November 2025 the city piloted flexible delineator posts inside the painted curb extensions, but within a month most posts had been struck, dislodged or lost, prompting the switch to the more durable wedges. Phase 1 also includes painted curb extensions at all intersections, expected to be complete in fall 2026; Phase 2 will study raised crosswalks on the west side of each intersection. Parking is largely unaffected, apart from removal of a loading zone at the southeast corner of Glenwood Avenue and West North Street and a 20-foot eastward shift of the valet zone at Tucker Street.
