1. Safety Insights a. Analytics with the following specifications i. Real-time identification of traffic violations, including: 1. Illegal pedestrian crossing events, signal violations, and red-light violations, 2. Illegal turning movements, lane compliance violations, stopped/disabled vehicles, and wrong-way driving, 3. Near-miss events between vehicles and fixed objects, between vehicles, and between vehicles and vulnerable road users (VRUs), 4. All crash events between vehicles and fixed objects, between vehicles, and between vehicles and VRUs. ii. The system must provide data for each event, including date/time, vehicle speed(s), post-encroachment time (PET), time-to-collision (TTC), road user class, conflict type, and movement direction iii. Ability to filter events by severity and link to other related events (e.g., nearmiss tied to red-light violation) b. Reporting Specifications i. Visualization of events with related video and metadata, including: 1. Event type, date/time, vehicle speed, direction of travel, and signal phase, 2. Statistical reports on event frequency by user-defined time intervals, including day of the week and 5, 15, 30, and 60-minute intervals, 3. Ability to filter metadata and export raw data in .csv, .pdf, and .png formats, 4. Creation of heat maps and aggregated reports based on crashes and near-miss events, and display crash type, severity, day of the week, time of day, movement, and direction, 5. Assign safety scores based on configurable parameters for each location, with a ranking of the worst-performing intersections. 2. Traffic Insights a. Analytics with the following specifications: i. Detection, counts, and classification of vehicles and VRUs in real-time, ii. Measurement of road user speed, road occupancy, and density at intersections and road segments, iii. Calculation of peak traffic hours and average vehicle delay by approach, movement, and overall intersection delay. b. Reporting Specifications i. Statistical reports on vehicle counts, classification, and intersection movement, approach, overall delay by date range and time intervals ii. Industry standard Automated Traffic Signal Performance Measures (ATSPMs) reports with filterable date and time, and daily ATSPM watchdog reports to identify abnormal signal activity iii. Visualization of data in charts, graphs, and tables, with exportable formats 3. Connected Vehicle Messages a. The system must generate and transmit V2X messages per Society of Automotive Engineers (SAE) standards (J2735, J2945, J3224) including: i. Signal phase and timing (SPaT), intersection and roadway lane geometry (MAP), and Basic Safety Messages (BSM) for vehicles, with lane-level localization and speed prediction, ii. Passenger Service Messages (PSM) for VRUs with intent predictions and conflict avoidance iii. Signal priority/preemption, roadside alerts, and collision avoidance messages, iv. Flooded roadway alerts, v. Transmission over dedicated, short-range communications (DSRC), cellular vehicle-to-everything (C-V2X), and cellular networks with support for geofencing and VRU safety alerts.
