QUESTION NO. 28

QUESTION: Councillor J. Sinnott

To ask the Chief Executive to advise whether traffic volume and potential increase in traffic volume are taken into consideration when decisions on planning are made?

REPLY:

Traffic and Transport Assessments and / or Workforce Travel Plans (also known as Mobility Management Plans) are required to support development proposals that have the potential to generate significant traffic movements, to demonstrate that there is public transport carrying capacity and road capacity to serve the development

The County Development Plan states in SM6 Objective 8 'To require all major traffic generating development to submit a Mobility Management Plan / Workforce Plan and / or Traffic and Transport Assessment'

Traffic and Transport Assessments (TTAs) provide a framework for an integrated approach to development which ensures that proposals promote more efficient use of investment in transportation infrastructure, reduce travel demand and promote road safety. TTAs should address the impact of the proposed development on the local and broader street network and should provide a clear rationale for the proposed level of car parking having regard to the existing and potential availability of public transport services in the area.

Traffic Impact Statements will be required for all major traffic generating development as defined by the Traffic and Transport Assessment Guidelines (2014) published by the National Roads Authority (NRA) (now Transport Infrastructure Ireland (TII)). The Planning Authority may also require such assessments where a particular development may have a significant impact on the County road network. All such statements should also be prepared in accordance with the Guidelines.

Traffic Assessments will be required to demonstrate that sufficient, realistic and verifiable levels of public transport carrying capacity and road capacity will be provided for, in a sustainable, phased manner, so as to cater for all new trips to be generated by the development.
