- 23. Policy Influence: Sustainable Communities Sustainable Communities are places where people want to live and work, now and in the future. They meet the diverse needs of existing and future residents, are sensitive to their environment, and contribute to a high quality of life. They are safe and inclusive, well-planned, built and run, offer equality of opportunity and good services for all Delivering Homes Sustaining Communities: Department of Environment, Heritage and Local Government

Notes de l'éditeur
- Ideal PRD = 1 Acceptable PRD = 1.5 This is not untypical for Blanchardstown.
- If we look closely at the mode split in Blanchardstown we see a similar mix of the modes to that of the national average. Obviously the motorcar dominates, there is a high level of car passengers – which should be interpreted as Children. There is a low level of Bus, Minibus and Coach users. The bicycle has a tiny slice of the pie.
- Ciaran has explained how we put the community survey and Powcar data sources to use. GIS was used in part analysis of these. The next section is very much the backbone GIS analysis to the project. We knew we lacked accurate data to do any real analysis for this stage. In order to progress, we commissioned CI for 4 months to carry out a detailed survey on the ground. They surveyed on a bike and recorded features which were required to look at permeability/accessibility in the study area. On which we carried out analysis. Key Neighbourhood services - schools, shopping areas – parks - playgrounds ******************************************************************************************************************************************* While all the elements of the study were in GIS this next part is very much the GIS backbone to the project. In order to progress the project we commissioned Compass Informatics for 4 months to carry out a detailed survey on the ground. They headed out on a bike and recorded features which made up a network On which we carried out analysis. This was done as we lacked accurate and complete data of the study area.
- Delineate an area according to the number of houses which fall within it.. Here 1000 houses in blue area.
- Todd Randall documented a method for measuring permeability Measure of how direct it is for people to get to their local service. 1 is the ideal answer – 1.5 consisted acceptable PRD
- Todd Randall documented a method for measuring permeability Measure of how direct it is for people to get to their local service. 1 is the ideal answer – 1.5 consisted acceptable PRD
- Look at whether the PRD is above or below 1.5 , is their journey direct and also is I long above or below 700m
- NOTE: NB – this PRD included Desire lines and high difficulty.
