The urban transportation infrastructure that we have inherited from previous generations is centered largely around the needs of vehicular traffic, with little or no regard to accommodating the needs of a growing pedestrian population. One of the key challenges in enabling smart urban communities lies in integrating pedestrians’ needs into the design of the urban infrastructure. For example, lack of timely support to cross the streets at intersections, particularly in inclement weather conditions, frustrates many pedestrians and is conducive to jaywalking, a well-documented source of pedestrian fatalities in big cities. It is, therefore, of a fundamental importance to provide pedestrian-centric services, particularly for vulnerable pedestrians such as children, the elderly, and the disabled. This proposal aims to develop and build CrossGuard, a system which will make crossing at intersections safer and, in the process, elevate pedestrians' quality of experience. CrossGuard will explore new opportunities available at the nexus of intelligent infrastructure, data analytics, intelligent sensing, and engaged pedestrians towards Vision Zero, a world-wide initiative that aims for zero traffic fatalities. The design of CrossGuard is inspired by human crossing guards, often stationed at busy intersections, most notably near schools. Just like a vigilant crossing guard, CrossGuard will anticipate pedestrian needs and accommodate them promptly and effectively. We expect this project to have a profound and lasting societal impact. The objectives of CrossGuard will be realized via the exploration of four research questions: (1) Investigating and developing an understanding of the challenges facing the pedestrian community; (2) Designing algorithms to identify vulnerable pedestrians and developing stochastic models for ensuring that they can cross safely; (3) Developing sensing modalities and resource allocation strategies for the successful provisioning of CrossGuard’s services; and (4) Expanding CrossGuard to non-signalized intersections. The team will actively engage citizens and officials from the cities of Norfolk and Virginia Beach in a meaningful dialogue via focus groups and workshops. They will also make efforts to ensure participation from a representative cross-section of the citizens, particularly parents of school-age children, the elderly, and people with disabilities. The team envisions that the wealth of real-time traffic data collected in conjunction with perceived traffic trends will make the seamless integration of pedestrian and vehicular traffic possible. In turn, this will offer new opportunity for connected urban spaces, and will drastically reduce traffic accidents involving pedestrians, especially children.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

我们从前几代继承的城市运输基础设施主要围绕着车辆的需求，几乎没有考虑满足不断增长的行人人口的需求。使智能城市社区的主要挑战之一在于将行人的需求整合到城市基础设施的设计中。例如，缺乏及时的支持无法在交叉路口越过街道，尤其是在越来越多的天气条件下，会使许多行人感到沮丧，并正在向杰伊·沃克（Jaywalking）进行，这是大城市中有充分记录的行人死亡人数的来源。因此，提供以行人为中心的服务，特别是对于弱势行人，例如儿童，老年人和残疾人，这一点至关重要。该提案旨在开发和建造CrossGuard，该系统将使交叉点更安全，并在此过程中提高行人的经验质量。 CrossGuard将探索智能基础架构，数据分析，智能敏感性和订婚的行人诺斯（Vision Zero）的新机会，这是一项全球范围内的计划，旨在使零交通死亡。 CrossGuard的设计灵感来自人类越野后卫，通常驻扎在繁忙的十字路口，最著名的是在学校附近。就像警惕的交叉警卫一样，CrossGuard将期待行人的需求，并迅速有效地容纳他们。我们希望这个项目将产生深远而持久的社会影响。越野的目标将通过探索四个研究问题来实现：（1）调查和发展对行人社区面临的挑战的理解； （2）设计算法以识别脆弱的行人并开发随机模型，以确保他们可以安全地越过； （3）开发灵敏度方式和资源分配策略，以成功提供越野服务； （4）将横守扩展到非信号交叉点。该团队将通过焦点小组和讲习班进行有意义的对话，积极与诺福克和弗吉尼亚海滩城市的公民和官员互动。他们还将努力确保公民的代表性横截面，特别是学龄儿童，年龄较大和残疾人的父母。该团队设想，与感知的交通趋势一起收集的大量实时交通数据将使行人和车辆交通的无缝集成成为可能。反过来，这将为连接的城市空间提供新的机会，并将大大减少行人涉及的交通事故，尤其是儿童。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估，被认为是珍贵的支持。
