Temporary Traffic Management (TTM) Consulting
Smarter Traffic Management, Safer Projects
Temporary Traffic Management (TTM) is changing in New Zealand. The NZGTTM guidelines emphasise a risk-based approach - moving away from rigid templates toward smarter, site-specific solutions.
Corridor Solutions helps contractors, developers, and councils navigate this shift. Our independent consulting ensures your on-site TTM processes are safe, compliant, and cost-effective.

How much temporary traffic management does a job need?
As much as the risk on that site calls for, which on a quiet street or a short job can be far less than expected. On small work, the cost of hiring a crew for the day can be more than the job itself, and a risk-based plan will often show that a contractor's own trained people, using gear they already own, can run the site safely. Where the risk is higher, the plan says so plainly and sets out what is needed. Ashley presented on exactly this at TARMAC25, in a session called "Demystifying NZGTTM Risk Assessment", and because we do not supply crews or equipment, we have no reason to push the answer either way.

Why independent advice matters
A full-service traffic management company has an incentive to over-specify: more cones, more signs, more crew means more revenue. We do not supply crews or equipment, so our TTM advice is written purely against safety and compliance, with cost efficiency built in.
Ashley is one of the lead Technical Advisors to the CoLAB RATA Technical Advisory Group for NZGTTM and has run workshops for council Traffic Management Coordinators on assessing NZGTTM plans. We worked with Inframax on their transition from CoPTTM to NZGTTM across the Ruapehu, Waitomo and Ōtorohanga district council maintenance contracts, and built an in-house tool that assesses and compares the risk of different TTM approaches as part of it.

Frequently Asked Questions – TTM Consulting
What is Temporary Traffic Management (TTM) Consulting?
TTM consulting is independent advice on how your sites set up and run temporary traffic management. We review live worksites and your processes against NZGTTM, recommend practical changes your crews can apply, and help your team build the skills to assess risk themselves, so you rely less on outside help over time.
What’s changing with NZGTTM?
The new guidelines shift from a “one-size-fits-all” approach to a risk-based model, requiring more practical, site-specific planning.
