Working Groups

The RSMP Nordic Working Groups discuss specific topics and produce proposals for review by the Board. The working groups are where we shape the next versions of the RSMP specifications.

Most working groups focus on technical issues, like developing the RSMP specification and tools, but workings groups can also handle things like communication, outreach or funding.

The working groups reflect the latest Activity Plan agreed by the Steering Group, and can also be created ad-hoc by the Board as needed.

Meeting summaries can be found at our main RSMP discussion area.

Anyone interested can join the RSMP working groups, but only RSMP Nordic partners can be listed as co-authors of proposals. Please contact the secretariat for more info.

SXL Standardization

Standardize and publish SXLs for other types of equipment.

RSMP can be used for many different types of equipment, and this is indeed already the case in many cities. However, only the SXL for Traffic Light Controllers have been standardized by RSMP Nordic all other uses of RSMP for other types of equipment rely on custom SXLs. This means every project reinvent the same type of messages, and that equipment and systems using these custom SXLs are incompatible.

The initial proposed list of equipment types to support include, Variable Message Signs, Traffic Counters and I/O devices.

Timeline

Release in spring 2024 (tentative).

Schedule

Biweekly online meetings.

RSMP 4

Research the opportunities of a core version 4.0, as well the resources and risk that would be involved.

Version 4.0 would include larger changes that solve some of the limitations of the existing specification but might not be backwards compatible.

Questions to be answered include:

• Opportunities and benefits?
• Resources required?
• Risks involved?

The goal is to answer these questions and provide a recommendation on whether and when to move ahead with Core 4.0 or focus on more conservative releases of the 3.x series.

Timeline

Decision on v4 at end of 2023, release in 2024 (expected to move).

Schedule

Biweekly online meetings.
