The Dublin Commuter Coalition said: “It looks like the Grangegorman filtered permeability scheme is dangerously close to being removed. Please please email your Central Area Committee councillors before the vote on the 12th and ask them to support the scheme! This is very important.”

The Dublin Cycling Campaign said: “If you’d like to see the quiet street in Grangegorman retained, please contact your local city councillors this week and let them know. They’re going to decide the future of the modal filter on January 12th. Councillor contact info here.”

Dublin City Council has issued a report on the trial outlining a large uptake in cycling on Grangegorman Lower.

It also said that speeding by motorists has decreased. The council said that the 85th percentile “vehicular speeds on Grangegorman Lower has been significantly reduced by 38% from 2017 levels of 60km/h to 37km/h during the trial.”

Dublin City Council also said that of the 974 emails which were received from July to December 2020 via its dedicated email address, 60% (586) supported the trial and 39% (378) did not support it, while 1% (10) had
no opinion.

The council report said: “Filtered permeability measures are not about rewarding one group of people while punishing another, but about making long-term decisions about how people travel, by delivering safer environments for people to travel by a range of sustainable modes. Pre-implementation traffic surveys show that a high volume of motor cars travel through this residential area despite the fact that 60% of households in the Grangegorman Area do not have access to a car and more than half of commuters (56%) either walk or cycle.”

It said: “Having gone through the process, our recommendation is to make the filtered permeability permanent as this type of scheme is fully in line with DCC policies and it has been shown to be beneficial and to achieve a marked improvement in safety and ability for people of all
ages to walk and cycle in this area.”

The report added: “If the elected members are concerned about the impacts of the scheme once the Covid-19 restrictions have been finally lifted and the full numbers of students and staff are now in place using the campus, we are agreeable to having a 12-18 month review period where a detailed report can be brought back to the members on how the scheme has impacted as Covid-19 restrictions have been lifted.”
