Land use

Highest levels of growth near SP and RJ Metropolitan areas

Reduction in growth rates due to economic and political crisis

Industrial growth outside SP and RJ metropolitan areas creating a generalized growth tendency

Formation of development centres with similar growth rates

Highest levels of growth near SP and RJ Metropolitan areas

Low growth rates elsewhere in the PDH region

Generalized high numbers and growth rates

Considerable reduction due to law enforcement and traffic safety measures, but still high

Sharp reduction combined with soaring numbers in different road segments

Suburbanization in SP and RJ metropolitan areas converting rural into residential and industrial land use

General increased in suburbanization levels

Industrial land use dominating outside the metropolitan areas

Localized changes at slightly slow growth rates

Densification of urban and industrial land use in the development centres

CASE STUDY

The charging system may also result in saturation (land use and transportation) of those areas in between toll plazas.

Current tolling system may create negative impacts in terms of limitations to development due to the increase in direct (user perceived) transport costs; and

Changes and complex AS-TS interrelationships only detected because a multidimensional time-series database was created for the PDH region

And in New Zealand….?

IMPACTS: NZ CONTEXT

Proposed framework: information on land use-transport interactions.

Land Transport Act and Land Transport Strategy: need for assessment frameworks that holistically incorporate impacts.
