We are in reality; the population density does not add up to the demand forecast.

Explain how a population of 44,200 people, 2,600 parking spaces plus an airport with 20m p.a.x will deliver 35m passengers per year.

I am going to keep posting the material below until you answer the question

There are three key flaws in this document firstly it does not give annual predictions for any location purely hourly capacity.

Secondly population density; the stated population density is 1,300 people per square kilometre on the route; taking 1 kilometre as being a realisitc walking distance the catchment of Metro North would be 34 square Kilometres which would give a catchment of 44,200 people

Thirdly the EIS that you kindly posted a link to lists a total of 2600 car spaces which is you give ridership figures of 1.5 cars per day only produces 3,900 journeys per day or assuming a six day week an annual total of 1.216m per year.

Add 8m airport passengers and you see that the 54,127 figure I gave by including all potential electoral wards as opposed to the sections of those wards that were convenient was a very safe bet.

Real demand based on the RPAs own figures in annual terms would be catchment 7.596m, Airport 8m and park and ride 1.216m or a total of 16.812m

Finally compare Budapest with a population density of 3,500 people per square kilometre and Metro North with a population density some 37% of the Budapest figure but Metro North has an hourly capacity 51.5% higher than a line with three times the catchment.

I am really starting to have my doubts as to how this project ever got off the ground; Luas is deemd adequate with a capacity of 4,650 per hour on the same population density.
