Freight Matrix Development Project

The Freight Matrix Development Project involved reviewing data sources including eRUC and FIGS and the development of a tool for data manipulation and extraction of origin-destination matrices. This has led to the development of Freight Matrix Road Map tool that allows the analysis of the spatial and temporal coverage of the EROAD data set.

The EROAD (eRUC data set) containing simple point data from the GPS and amplifying data which provided information including: ebox ID, time, course, speed and odometer. The web based tool developed allows the user to extract data in a number of ways:

  • Produce OD matrices at regional council, district, census area unit
  • Plot trips made by an individual Ebox for each day of data
  • Produce screen line counts at any location, which show the number and time of freight vehicles passing, as well as plotting those vehicles journey route
  • Produce two (or more) screen lines together to capture journeys taking a specific route, and the journey time between the two points



Auckland Motorways Interactive Ramp Signalling

Working collaboratively with Auckland City Council, this project involved the installation of 61 ramp signals on the Southern, Northern and Northwestern motorways.  This is part of a comprehensive motorway management system which has now been completed. A further 33 ramp signals are located along the Western Ring route between Manukau and Albany whilst the new road is under construction. Auckland is the first city in the world to have the entire motorway system fully and interactively managed by ramp signals.

The benefits include:
  • More consistent and predictable travel times
  • Safer merging
  • Fewer accidents
  • Better throughput of vehicles on the motorway
  • More consistent speeds

The measured results show that with the ramp signals operating, there is an overall 15% improvement in travel speeds and a 5-15% increase in the rate of vehicles flowing on the motorway.



Joint Traffic Operations Centre, JTOC

On 31 May 2010, a new $6.5 million traffic operation centre opened at Smales Farm, providing a hub that enables New Zealand to monitor its highways on a nationwide basis.

  • The centre monitors and manages what’s happening on 8,000km of roads and motorways 24 hours a day, 7 days a week, 365 days of the year.
  • This centre contains New Zealand’s largest video wall. More than 200 closed circuit cameras transmit live images into the control room for operators who monitor traffic flows,  manage roadway incidents and adjust the region’s 700 sets of traffic signals.
  • This centre is part of a national network for managing traffic operations on state highways throughout New Zealand.
  • Drivers can look forward to a new information service, with 150 electronic message signs being progressively commissioned over three months.
  • The centre also provide traffic updates to radio stations and websites to give accurate and timely information to motorists.
  • The Northern Busway and Northern Gateway Toll Road operations are also run from the centre, and the NZTA has designed the new facility so that it can be integrated more effectively with other regions.
  • Outside of Auckland, the centre manages Wellington’s roads at night, and it controls roadside electronic messages on the State Highway network.
  • The NZTA has designed the centre so that it can be integrated more effectively with the rest of the country to deliver benefits for drivers at both regional and national levels.
  • The NZTA is forecasting $53 million in productivity gains per year from the new centre. It says providing reliable travel information helps to avoid crashes, clears those that do occur more quickly and safely, and makes more efficient use of the existing motorway system by reducing travel times, energy consumption and pollutants.



Auckland Harbour Bridge Tidal Flow, Barrier Machine & Lane Control Signals

The Moveable Lane Barrier was the first ever permanent lane barrier system on a major bridge anywhere in the world. It was introduced in 1990 to manage traffic flows. Moveable lane barriers improve traffic flow by increasing the number of available lanes and maximising capacity on the bridge during peak times through the so-called ‘tidal flow’ configuration.

The new Moveable Lane Barrier, changing the lanes over on Auckland Harbour Bridge now takes approximately half the time. A new, more efficient moveable lane barrier and two new machines were installed on the bridge in March 2009. The new barrier machine, designed for flexibility, can perform variable shifts which means the width of the lane is adjustable. The future proof design can also accommodate further extensions to the traffic tidal flow systems. Motorists now see a slightly narrower barrier system and new generation machines that have superior efficiency and are able to perform the lane change almost twice as fast, reducing changeover time to 20 minutes.



Public transport traveler information (RTI - Real Time Information)

  • RTI is up-to-the minute information on when a bus or train service is due, based on where the vehicle actually is (from GPS vehicle tracking) – rather than where it should be.
  • RTI has been progressively introduced across the Wellington region.
  • The rollout of display signs was coordinated with the introduction of RTI on each bus and train operator’s services.
  • Around 190 electronic display signs have been installed at key bus stops.
  • Another 60 display signs were installed at most train stations.
  • When a bus or train is being tracked the times shown are the actual number of minutes until that vehicle arrives at the relevant stop or station, for example, ‘12min’ or ‘Due’ if the service is less than 90 seconds away.
  • RTI is smart. It constantly learns the effects of different conditions on different days and uses this information to ensure accurate predicted arrival times. In the case of major service the Regional Council has integrated this project with computers controlling the city’s traffic signals. The plan is that when buses are running late, they can be given priority at intersections.



National Traveller Information System

Some of our success stories include:

Journey Information Signs - NZTA’s new service sees the installation of 130 journey information signs which are being progressively commissioned on the approaches to motorway on-ramps. The electronic message signs show expected journey times in minutes for travel via a motorway. The signs display three main destinations with the information being updated regularly as traffic conditions on the motorways change.

Live traffic webcams - In a number of areas around the country you can check the real-time traffic conditions before you get on the road. Our traffic webcams are located at key points on the highway network and show you what’s happening with the traffic right now.

InfoConnect is a NZTA initiative to supply timely and accurate state highway road traffic data to the developer community, so they can add “value” to this and create innovative traveller information services for the public. InfoConnect is a web portal with a range of application programming interfaces (API”s) providing anyone free access (after registration) to verified real time traffic data. The range of API feeds includes:

  • roadworks;
  • incidents;
  • congestion;
  • web cameras;
  • estimated travel times; and 
  • location referencing.

Truck Fuel Savings using live driver feedback to modify driver behaviour

Real-time driver behaviour and its impact on fuel consumption has been very difficult to quantify.The truck fuel savings project uses the iBright telematics system and its measurement of the real-time data from the engine management system, combined with g-force data, to quantify the impact driver behaviour has on fuel consumption, to provide immediate feedback to the driver and to enable management to access and act on the data as required. The project assesses:

  • Driver behaviour and fuel consumption before application of the ibright system
  • Driver behaviour and fuel consumption following education measured without direct and immediate driver feedback
  • Driver behaviour and fuel consumption following addition of a real-time in-cab driver scoring system.

The project has identified the most important areas to target to enable immediate and measurable gains in safety and fuel consumption, reducing operational costs for transport operators. It has also enabled continuous improvement.

The iBright system is also one of the two approved electronic distance recorders in the New Zealand National Mass Distance Road User Charging System.
