DATA BLOG: How, when and where we travel

The National Transport Authority (NTA) launched its draft strategy for the Greater Dublin Area recently. The NTA stressed at the time that it was not just a list of projects, as shown below it’s also based on fairly substantial data. Here, we reproduce some of the interesting graphed data from the strategy.

Population share by area

Graphs showing data for 1996 and 2006, and the predictions for 2030. Unlike what some would have you think, the bulk of people are and will remain living inside the M50, the vast bulk inside and round the M50:

The NTA writes:

In the period up to 2030, all areas of the GDA are expected to see a growth in population, with the fastest rate of growth expected in the city centre and the Metropolitan outer suburbs. In addition, the share in the rural Hinterland and lower order Hinterland towns is expected to be lower and this would be a significant change, when compared with recent trends in Hinterland growth.

Distribution of jobs within the GDA

distribution of jobs

The NTA says:

800,24013 residents of the GDA were in employment in 2006, an increase of over 40% on the previous ten years. The largest growth took place in the inner and outer suburbs, in areas which have poorer public transport accessibility compared to the city centre. Since 2006, employment has contracted due to the economic downturn with 765,000 people in employment in the third quarter of 2010.

The employment forecasts used in the Strategy assume that the 2006 ratio of employment topopulation will remain constant up to 2030 at national and GDA level. This means that for theGDA an increase in employment of 39 % over 2006 levels is expected.15 Growth in jobs is expected in all locations up to 2030.

In terms of the location of jobs, the fastest rate of jobs growth is expected to take place in the city centre and the Metropolitan Area outside the M50. Figure 4.4 represents the distribution of jobs within the GDA inclusive of people commuting into the GDA.

Travel patterns in the Greater Dublin Area (morning peak period)

Journey purpose and time of travel

Based on a DTO (now NTA) 2006 survey:

Mode share and distance travelled

Based on 2006 census data. These are split into three images for easier viewing, click on each one to zoom in. We also adjusted these graphs to show the shorter distances in green and the larger distances in red (the NTA had two light blues representing one of the shortest and the longest distances).

Inside the M50:

Outer suburban and hinterland towns:

Rural hinterland:

The NTA says:

The places in which people live in the GDA havea major influence on how far they travel to work,education or other activities, and how they getthere. The majority of people inside the M50 (citycentre and inner suburbs) travel less than 5km towork, whereas in the Hinterland area, most peopletravel over 10km to work. Around 50% of thoseliving within the M50 use the car to travel to work.In the Hinterland area, that figure rises to over 80%.
