Temporary Traffic Management (TTM)

Highway Management Maintenance (HMM) provides an Infrastructure Management service for Temporary Traffic Management (TTM), gully emptying, sweeping, winter gritting and other duties, to cover all aspects of operation & maintenance for road, pavements and car parks.

HMM’s experience has been gained through operating and maintaining the 60km stretch of the most trafficked part of Northern Ireland’s motorway network from “Sprucefield” on the M1 through to the “Westlink”, M3, M5, A8 (M) and the M2 through onto the M22.

HMM PROVIDE AN INCLUSIVE TTM PACKAGE TO THE FOLLOWING STANDARDS ON ROADS IN N.IRELAND

All TTM is planned, designed, organised and carried out by HMM staff using a variety of day and overnight closures with restricted working timescales to minimize disruption to the travelling public.

STANDARD ROAD CLOSURES:

Are those which are allowed to remain in operation in all traffic flow and visibility conditions. They include all works involving contraflows and other works of long duration.

RELAXED ROAD CLOSURES:

Are those which are allowed to remain in operation only when the traffic demand is less than the available carriageway capacity and when visibility is good.

MOBILE LANE CLOSURES (MLC):

Techniques are carried out in good visibility, during periods of low risk when traffic flows are low and congestion is unlikely to occur.

CHAPTER 8

Chapter 8 recommends the type of traffic management measures to be adopted which are dependent upon the type of works and their duration, the highway layout, and the nature, volume and speed of the traffic.

This Code of Practice is intended to provide guidance to everyone designing or undertaking works on the highway, in the selection of the most appropriate form of traffic management in accordance with the recommendations contained in Chapter 8.

All TTM layouts are designed in-house by HMM staff to the requirements of The Traffic Signs Manual, Chapter 8 and distributed to all interested parties for comments before implementation.
