Land use-transport integration diagnosis and identification of priority areas.

The land use transport integration diagnosis provides a comprehensive framework for analysing and understanding the whole system of land use transport dynamics on a metropolitan scale. This is also useful for detecting intermodal stations for priority intervention.

This tool assists planners by providing a set of indicators that describe diverse insights of mobility and urban planning at a city-regional level. This makes it useful for general diagnosis, but also for guiding mobility and urban planning policies or global strategies.

The proposed indicators per theme are the following:

–transport demand: total demand, demand per mode, user types, population covered. – mobility integration: lines per mode, closeness centrality, straightness centrality, betweenness centrality. –urban integration: global integration, urban integration. –urban environment and land use: road density, built floor surface, open space ratio, built surface per land use.

The tool also makes it possible to identify particular cases that may become priority areas for intervention. However it remains flexible in terms of criteria.

Various types of complementary tools are required to calculate some of the indicators (mostly GIS and transport models). A statistical software package is then needed to obtain the final results

Good practice

A similar approach has been applied in many urban areas, according to Bertolini’s “node-place model”. This model helps to value each location or urban environment independently from the transport point of view (“node value”) or land uses (“place value”), so that planners can achieve the level of land use-transport coordination and also identify those “unbalanced” locations. This model has been applied in the Netherlands, Tokyo, Helsinki, etc. (see References).

Application in NODES sites:

This tool has been evaluated by the Budapest NODES site.

The Budapest team considers the tool to be really useful and relevant, although “it assumes lots of time, budget and sophisticated project-management to create an accurate analysis.”

This tool has been given a 4-star rating (****)


Potential interchange performance improvement

This tool provides a framework to discuss global strategies and understand current land use-mobility relationships in a quantified and objective way. At a city/regional level, decisions may involve major economic or political issues. Consequently, an objective, technical framework to quantify relationships and future associations may be really helpful.

When studying developments over a long period of time, it is also useful to evaluate overall trends and improvements in the mobility/land use relationships and the contribution to the implementation process of interchange improvement (Process evaluation)
