traffic congestion

The road network is over capacity and traffic congestion could be reduced by walking, cycling, taking public transport or working from home, the department has said.

Mr Woods said investments, such as Belfast Grand Central Station, were what would make a material difference to traffic congestion.

Mr Woods said a car share initiative could be part of transport policy in the future but it would not solve the current traffic congestion issues.

"As cities worldwide promote increased use of public transport to combat traffic congestion and meet climate goals, it's essential that passenger comfort and safety are prioritised to encourage more people to choose buses over private vehicles," said Professor Eager.

Speaking at the scene, Station Commander Mike Watts said road closures were in place and urged people to avoid the area due to smoke and traffic congestion.
