US: SAE Signal Control Messages - WAVE WSMP

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Signal Control Messages with those for V-X: WAVE WSMP. The US: SAE Signal Control Messages standards include upper-layer standards required to implement signal control information flows. The V-X: WAVE WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

Comm Profile: V-X: WAVE WSMP

Level	Doc #	Standard	Description
Access		Bundle: WAVE - Subnet	A bundle of standards specifying the lower layers of the reference communications model for the US DSRC environment.
Security		Bundle: IEEE 1609.2	A bundle of standards that groups a set of IEEE security standards together for easy reference.
TransNet	IEEE 1609.3	IEEE 1609.3 WAVE - Networking Services	This standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single-hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP - a common message format specified in ISO 16460.

Data Profile: US: SAE Signal Control Messages

Level	Doc #	Standard	Description
Facilities	SAE J2735	SAE J2735 DSRC Message Set	This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
Facilities	SAE J2945	SAE J2945 DSRC Common Design Elements	This standard defines cross-cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
ITS Application Entity	CTI 4501	CTI 4501 CI Implementation Guide	This Connected Intersection (CI) Implementation Guide defines the key capabilities and interfaces a connected signalized intersection must support to ensure interoperability with production vehicles for state and local IOOs. A connected intersection is defined as an infrastructure system that broadcasts SPaT, MAP, and position correction data to vehicles.
ITS Application Entity	ISO 19091	ISO 19091 V2I for signalized intersections	This technical specification defines messages and related data structures and data elements for the following exchanges between roadside equipment and vehicles: 1) Definition of the SPaT (signal phase and timing) message transmitted from a traffic controller that describes the state of the signals, signal timing as necessary to support the applications identified herein; 2) definition of the MAP message (which include the definition of motorized lane, vehicles, busses, trams, bicycle, pedestrian crosswalks, etc.); and 3) definition of the messages (SRM, SSM) to be exchanged between an intersection traffic controller and approaching vehicles to support priority treatment as might be expected for emergency response , freight transport, and public transport vehicles to improve safety.
ITS Application Entity	SAE J2735	SAE J2735 DSRC Message Set	This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application Entity	SAE J2945/B	SAE J2945/B Signal Intersection Applications	When identifying the content of this report, one of the goals was that it supports a nationally interoperable method for connected vehicles (CVs) to make traffic signal priority and/or preemption (TSPP) requests of connected intersections (CIs) that support priority and/or preemption services. Given that, this report specifies the over-the-air (OTA) interface between CVs and CIs to support TSPP applications using updated revisions of the SAE J2735 Signal Request Message (SRM) and Signal Status Message (SSM) and the use of a Wireless Access in Vehicular Environments (WAVE) Service Advertisement (WSA) to advertise support for TSPP at a CI. Included are a concept of operations, requirements, design, and message structure definitions developed using a detailed systems engineering process.

Readiness Description:

One serious or several significant issues. This category often includes proprietary or partial solutions. The communications solution may fail to provide even a base level of interoperability and security. Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
