How will Bluetooth Technology help Christchurch?

What can be done about all of this? Last week, Jim Harland, regional director of the New Zealand Transport Agency (NZTA), proposed a possible solution. Bluetooth technology could show where cars were headed once they left the northern corridor and were absorbed into the city.

Harland's team will use information gathered from bluetooth technology to analyse where people are going from the northern corridor.

The technology picks up a mobile device in a car and tracks where it goes.

"This gives us a real-time information - how long different trips take and where people are going," he said.

Regional Land Transport Strategy Monitoring – the meeting agreed to pursue the 
bluetooth/eRUC method to attempt to measure regional and inter –regional journey time 
reliability. NZTA are rolling out more Bluetooth monitoring sites and we may be able to 
expand this to include the regional strategic road network. It may be beneficial to get 
someone from BECA consulatants who are working with NZTA on the national Bluetooth 

monitoring to speak to RLTOG.
