National Land Transport Plan
The NZ Transport Agency is dedicated to helping local government and approved organisations with any information about delivering the 2018-21 NLTP. It has a new NLTP news page , a monthly NLTP newsletter and an online form for questions about the NLTP. Learning Zone resources include self-paced learning modules developed to support funding proposals, and guides for in-depth support using the Transport Investment Online (TIO) portal to develop transport programmes, regional land transport plans, 10-year forecasts and other work. You can find general information and timelines at planning and investment.

"New research into health effects of road dust."
Researchers in Canada have found a significant association between mortality and the coarse fraction of particulate matter attributed to road dust. Particulate matter less than 10 and 2.5 microns in diameter (PM10 and PM2.5) are key size fractions from a health perspective. The study has statistically analysed daily levels of particulate matter between 10 and 2.5 microns in diameter in seven communities against daily mortality over the period 2003-2015. It found that an 8.6 μg/m3 increase in the coarse fraction particulate matter (PM10 – PM 2.5) was associated with a 3.1% increase in non-accidental mortality during the road dust season.

"Why active transport matters: cancer and obesity links."
Research in the USA has identified that being overweight or obese are associated with an increased risk of at least 13 different types of cancer. About 55% of cancers diagnosed in women and 24% of those diagnosed in men are overweight- or obesity-related in the U.S.A. See report>>
"Aluminium origami creates effective traffic noise barrier."
Researchers at the University of Michigan, Ann Arbor, have used vertical cylinders mounted on a pre-creased sheet of aluminium to improve the performance of traffic noise barriers. The barrier can be adjusted to block noise at different frequencies and reduces acoustic energy by 90%. This is equivalent to reducing audible traffic noise from 1.6 km to 0.5 km. See report>>
