SBIR Phase II: A Cloud Managed Solution for Public Transit Signal Priority and Emergency Vehicle Preemption of Traffic Lights

小型企业创新研究(SBIR)第二阶段项目的更广泛影响/商业潜力是为专注于为移动性增加直接价值的应用程序的车辆到基础设施通信奠定基础。许多解决方案都专注于向车辆提供信息，而要求车辆信息更高效运行的往往是基础设施。目前，无论车载技术如何，交通信号都会强制执行每个人的通行权。这就是为什么优化它们对公路网的影响可以提供巨大的好处。交通也有很大的好处，比如公共汽车和轻轨，当在十字路口优先考虑时，提高了准时性能，这是乘客率的一个主要因素。拟议的项目推进了国家交通通信智能运输系统协议(NTCIP)的联合标准化工作，以实现不同交通信号控制器供应商之间的互操作性，从而实现不同运营机构之间的共享控制和组织。在同一小范围内，由地方、县和州管理道路路段并不少见。这些重叠的司法管辖区在道路网络中造成裂痕，导致交通信号灯的不同步计时。其目的是将管理整合到一个能够协调大范围交通信号的信号网络中，以提高移动性的整体效率。借助能够与每个联网路口通话的云解决方案，车辆遥测数据和路线信息可用于主动优化信号配时。将与公交车、消防车和救护车等优先车辆合作，进行试点研究，以在跨司法管辖区的路线上执行优先和优先购买权。每个试点案例将根据机构制定的关键绩效指标进行分析。这一裁决反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to lay a foundation for vehicle to infrastructure communication focused on applications that add direct value to mobility. Many solutions are focused on getting information to the vehicle, while it is often the infrastructure that requires vehicle information to operate more efficiently. Currently, traffic signals enforce the right-of-way of everyone regardless of in-vehicle technology. This is why optimizing their effects on the road network can provide tremendous benefit. There are significant benefits to transit as well, like buses and light rail that, when given priority at intersections, improves on-time performance which is a major factor in ridership rates.The proposed project advances the work of the joint standardization of the National Transportation Communications for Intelligent Transportation Systems Protocol (NTCIP) to achieve interoperability between various traffic signal controller vendors to enable shared control and organization between different operating agencies. It is not unusual to have sections of roadway be managed by local, county, and state within the same small area. These overlapping jurisdictions produce fractures within the road network resulting in the asynchronous timing of traffic signals. The aim is to consolidate the management into a signal network capable of coordinating large areas of traffic signals to increase mobility's overall efficiency. With a cloud solution that is capable of speaking to each networked intersection, vehicle telemetry data and route information can be used to proactively optimize signal timing. Working with prioritized vehicles such as buses, fire trucks, and ambulances, pilot studies will be conducted to perform priority and preemption along routes that cross jurisdictions. Each pilot case will be analysed based on key performance indicators set forth by the agencies.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.
