This probably requires a thread of its own since there's going to be so many different elements to it and will probably influence commuting in Dublin in the short term.

Targets and estimates based on the Canal Cordon Count:

Assumes a reduction in total number of people commuting to the city centre, car capacity limited by congestion and shorter pedestrian wait times and automated crossings implemented to avoid crowding, public transport capacity constrained by physical distancing, aiming to double the number of people walking and triple the number of people cycling.
Some highlights:
Pedestrian areas: Wider footpaths, bus stops moved to more spacious streets to avoid crowding, temporary build out bus stops to be trialled
Bike lanes: Temporary protected bike lanes at the Grand Canal, Pearse Street contraflow, Gardiner Street etc. and most of the radial routes near the city centre area.
Bus gate: Rathmines and Westland Row (potentially)
College Green: Services to be diverted gradually. Phased introduction of pedestrianisation and cycle route. Contraflow bus lane on Winetavern Street.
Some of the things in it have already started. Some will start in the coming weeks. The measures in the report are to be delivered in phases over 6-12 months.
