@Casserly_Rock To be fair I would argue to be lit up like a xmas tree at night as you won’t be seen otherwise, but during the day high-viz for pedestrians & cyclists is pointless. They get hit by cars not because they can't be seen but because of how streets are designed and how drivers behave

[West=On=Track @WestOnTrackIRL]

Reopening the #westernrailcorridor will be a significant, straight forward & hugely positive step in addressing the #infrastructure deficit of the region #sligo #mayo #galway @NWAssembly @WesternDevCo @Irelandwest @atusligo_ie @uniofgalway

[Geraldine Herbert @GerHerbert1]

Ireland’s share of pedestrian fatalities is nearly double the European average, making Ireland among the continent’s worst for pedestrian safety...Yet the 30km/h debate still revolves around how motorists will cope 🙄 @PatKennyNT @mcculld

[Mike Hudema @MikeHudema]

Remember - the wildfires, the droughts, floods, heatwaves happening across the world are within "safe" climate change (1.2°C warming). We are on course to double that.

No time to waste. #ActOnClimate

[Sebastián Tyrrell @STyrrellOU]

@murphy_policy @WestOnTrackIRL As well as. It’s a great cycling resource and I hear widely used for active commuting especially between Athlone and Moate. Here’s Streamstown station. It’s in the strategic rail review - reopen and extend to Cavan and Portadown. https://t.co/O86vS0ZDLp

It’s that time again! 💡 Join us this Monday 20 Oct, 16:45 by the Michael Collins Statue as we hand out free bike lights around Cork.

A bright, social evening to make our streets safer. We’ve got the lights, all we need is your energy! 💪

137 deaths so far this year. These are not accidents, these people have been killed - and many more left with life-changing injuries - through the policies we’ve chosen to implement and the attitudes we’ve allowed to take root. The government should be ashamed.

@IRVAroadsafety @MikeMcKillen @SeanCanney @DarraghOBrienTD And in doing do, rolling the dice on:
👊Fewer casualties
👊Fewer collisions
👊Cheaper motor insurance
👊More active travel
👊Cleaner air
👊Quieter streets
👊Safer journeys to/from schools
👊Greater health benefits
Very cowardly decision imho.

The murder of Charlie Kirk is part of a disturbing rise in political violence that threatens to hollow out our public life.

A free society relies on the premise that people can speak out without fear or humiliation.

No more political violence.

Come on @Munsterrugby, don’t be letting @RonanOGara10 set the pace. What about a similar sustainable mobility plan for Thomond and Musgrave?

One of the best programmes in Cork! Delighted to see such great participation. More people should definitely give it a try.

Movement of #freight is several times more carbon efficient on #rail than road. This one train from Ballina to Waterford saved ~5000kg of #carbon versus #roadhaulage #westernrailcorridor #modalshift @PortofWaterford @EPAIreland @DeptCEE @EamonRyan @IDAIRELAND @Entirl @IrishRail

Sligo’s (pop 20,000) first daily rail arrival is not until 10:16 AM. More early morning arrivals is a MUST to enable #commuting for #college #students #healthcare #tourism #employment #leisure @SligosBuzzin @SligoPPN @sligohub1 @SligoChamber @glasshousesligo @atusligo_ie
