为旧金山建设一条更好的主干道

Market Street has played a pivotal role in the development of the 旧金山市 as its main transportation corridor since it was laid out in 1847. Redesigned in the late 1960s and early 1970s through a collaboration by master architects John Carl Warnecke and Mario J. 奥·钱皮, 以及景观大师劳伦斯·哈尔普林, 市场街是现代城市规划的一个重要例子. 今天, it remains the core of regional transit service—as well as the backbone of transit connections throughout San Francisco.

更好的市场街项目是一个复杂的项目, multi-decade effort to redefine the future of the corridor to best meet the demands of 21st-century transportation mobility options, all while also enhancing 街景画 aesthetics and activating pedestrian zones for a broader array of uses. San Francisco Public Works is leading the Better Market Street project to deliver transformative transportation, 街景画, 2 .安全改进.奥克塔维亚大道和斯图尔特街之间两英里的市场街.

The primary purpose of the project is to make Market Street safer and more efficient for all modes of transportation by reducing conflicts between transit, 辅助客运系统, 出租车, 商用车辆, 骑自行车的人, 和行人. The secondary goals of the project are to replace infrastructure in the corridor that is reaching the end of its operational design life and to improve the accessibility of the corridor and the quality of its 街景画 environment.

Market Street is the main artery of San Francisco and the City’s Municipal Railway (Muni), 大部分路线在墟街或穿过墟街. 市场街是地铁系统中最慢的交通走廊之一, 平均速度约为5.1 mph on Market Street due to conflicts between different modes of transportation, 停止间距, 客运量大. 除了平均约250人之外,每天有000次过境登机, 市场街有大量行人使用(约85条),000 pedestrians per weekend day on Market Street) and has experienced a significant increase in the number of bi骑自行车的人 (a 183% increase between 1995 and 2015).

Market Street has multiple existing design deficiencies that contribute to a higher-than-average collision rate and pose potential hazards for all modes of transportation along the corridor. 2012年1月至2016年12月, there were 166 reported pedestrian collisions along the project corridor (137 collisions between vehicles 和行人, 行人和骑自行车的人之间发生了29次碰撞). 整个市场街的长度大约是0.4 percent of San Francisco’s total street miles but the site of 11% of the city’s severe/fatal bicyclist injuries and 6% of the city’s severe/fatal pedestrian injuries. On average, one person is killed each year along the Market Street corridor.

最后, the existing brick sidewalks and transit boarding facilities along the project corridor do not comply with the Americans with Disabilities Act (ADA), 给行动不便和视力受损的人带来挑战. 具体地说, many of the 1970s-era improvements to Market Street do not meet current life safety requirements; the Better Market Street project seeks to bring these elements up to current codes.

ICF协助 the City and County of San Francisco in navigating numerous design options and alternatives that had been conceived to address design deficiencies on Market Street. We prepared environmental documentation evaluating those alternatives determined to be most viable.

国际文化基金会还对文化资源进行了广泛的评估, including 146 historical resources within the Market Street corridor—consisting of historic districts, 纪念碑, and objects—and public infrastructure systems set against a backdrop of historic buildings. ICF’s cultural resources team balanced the need to meet the project goals with Market Street’s cultural and historical significance, providing a thorough analysis of project impacts to the numerous overlapping historical resources within the corridor and developing a robust program of mitigation measures to commemorate Market Street’s important history.

The ICF team also included sub-consultants Fehr and Peers and LCW Consulting, both of whom were crucial to evaluating the impacts of proposed lane modifications on the transportation system, 并与市政府合作，尽量减少这些变化的影响.

The environmental process conducted under the California 环境al Quality Act (CEQA) concluded with the approval of an environmental impact report and a preferred alternative in October 2019—with no public opposition.

A separate environmental process is underway to complete an environmental assessment pursuant to the National 环境al 政策 Act (NEPA). ICF与联邦领导机构密切合作, 加州运输部(Caltrans), 以及旧金山公共工程局加快《明升m88备用》的审批进程. This work includes collaborating with these agencies in frequent and intensive meetings and proactively anticipating and addressing issues. NEPA程序预计将于2020年8月完成.
