The Transport Agency will provide timelines for programme development as part of its planning & investment signals. Some of these will be indicative initially, e.g. NLTP adoption, until confirmed by the Transport Agency Board. Others will cover a broad timing range, given that different RTCs will establish different timelines for their regions. The timelines will also vary amongst RTCs depending on whether the RLTP is being developed or reviewed, and whether consultation is required if it is being reviewed.
