Intersection Safety Systems (ISS) Prototyping

Intersection Safety System (ISS) Prototypingperformance work statement (pws) OBJECTIVE, PHASING, AND TIMELINE The objective of this effort is to acquire ISS prototypes to assess the potential benefit and feasibility of broader ISS deployment. The ISS Prototyping effort has two phases: Phase 1: Prototype Development and Testing (Base Period) Minimum 12-month duration Maximum 18-month duration Phase 2: Prototype Refinement and Assessment (Optional Task) Minimum 18-month duration Maximum 24-month duration NOTE: Contractors may propose phase durations and corresponding deliverable schedules for each phase within the Government-identified minimum and maximum values. Figure 1 illustrates the two-phase approach, including the Government option decision prior to executing Phase 2. Figure 1. Two-Phase Approach for ISS Prototyping Phase 1: PROTOTYPE DEVELOPMENT AND TESTING (BASE pERIOD) The objective of Phase 1 is to develop and test initial ISS prototypes in an access-controlled testbed situated apart from public roadways and closed to the general public, hereafter referred to as a closed testbed. ISS prototypes must address high-value real-world intersection safety issues identified by a public sector partner. ISS prototypes are developed and tested iteratively in the closed testbed with public sector partner engagement. ISS prototypes are demonstrated and assessed for operational readiness at the conclusion of this initial phase. Each Contractor team must include: a lead entity responsible for ISS development and testing, an entity providing access to an accredited configurable closed testbed, and a public sector partner committed to the following activities by phase (documented in a letter of support): Providing supporting data and ensuring the prototype concept and testing aligns with high-priority intersection safety issues relevant to intersections under their jurisdiction (Phase 1). Supporting the installation of ISS prototypes in appropriate intersections under their jurisdiction in observe-only mode, with deployed ISS prototypes potentially taking specific real-time mitigating actions subject to prior approval (Phase 2). NOTE: A single organization may play one or more of these required roles. Using currently available data sources, the Contractor teams characterize high priority intersection safety issues under the jurisdictional control of the public sector partner. Contractor teams document observed intersection safety issues in a set of detailed use cases, scenarios, and operational conditions describing, at a minimum, location/geometry, weather/visibility, road user demand conditions, and observed road user behavior, among other factors. Contractor teams utilize the detailed use cases, scenarios, and operational conditions to develop a detailed Test Plan. The Test Plan must reflect, in structure and intent, the Government-provided high-level (experimental) test plan provided as Exhibit A: ISS Prototyping Phase 1 Test Plan Requirements of this PWS and required measures of effectiveness comprising both safety and congestion-reduction improvements. Note that Contractor teams are expected to share data obtained during the experiment, and later structure/process and share these data. Details regarding data sharing are included in Appendix A as well as below in the Task 1-7: Code/Data Sharing description. Within a configurable closed testbed, the prototype ISS is tested against the detailed Test Plan to address key research questions related to conflict prediction, identifying unsafe conditions, and proposed mitigation strategies. Contractor teams analyze data from the tests regarding the key research questions, and document findings in a final report. Contractor teams are required to demonstrate the ISS operating in real-time within the closed testbed for a delegation of USDOT subject matter experts. This demonstration is intended to show the nature and timing of strategies used to address unsafe conditions and mitigate individual conflicts. Based on the results obtained in the experimentation and demonstration, each of the Contractor teams assesses the deployment readiness of their ISS prototype in a summary report. Finally, Contractor teams share data and code from their experiments according to the Test Plan. In Phase 1, the Government seeks ISS prototypes capable of: Predicting and mitigating individual conflicts in real-time Conflicts are situations wherein the risk of imminent collision among specific nearby road users is high. The Government seeks ISS prototypes that are capable of predicting individual conflicts, e.g., an imminent collision between a vehicle and a pedestrian, and take an immediate mitigating action, e.g., issuing an auditory or visual warning to the vehicle driver, the pedestrian, or both. Characterizing unsafe conditions as they develop and making appropriate operational changes to improve intersection safety Unsafe conditions reflect more general operational conditions under which a high rate of conflicts and collisions has been observed in the past. The Government seeks ISS prototypes that are capable of characterizing and predicting unsafe conditions (e.g., unprotected left-hand turning movements across crosswalks with significant pedestrian volume) and make real-time operational changes to mitigate or eliminate the unsafe conditions (e.g., alter signal phasing to include a protected left-hand turning movement phase where conflicting pedestrian movements are not permitted and another phase where pedestrian movements are permitted and left-hand turns are not permitted). Implementing and testing practical mitigation strategies for predicted conflicts and/or identified or anticipated unsafe conditions, within the context of a closed testbed  Mitigating strategies may include the real-time modification of intersection control and/or the issuance of warnings.
