Directional Signing towards the Strategic Route Network

Discussion Paper

Community for Road Safety 道路安全研究小組 Component of Signing System

SRN Signing

• Guidance from districts and major traffic generators towards SRN entrance

• Guidance through SRN Interchanges and Exits

• Guidance from SRN exits towards districts

• Guidance between districts and smaller towns- generally via primary distributors and rural roads

• Local destination guidance - generally at proximity but related to exit and district signing Signing towards the Strategic Road System (SRN)

Signing of “” alone is important but insufficient Usage of route shield

• Route shield should only be used within the SRN or immediate approaches. Otherwise, drivers may not be able to identify whether they have already entered the SRN. This is particularly important if the connecting roads are themselves dual- carriageway roads with gantry signs.

Kwai Chung Road () is a dual carriageway primary distributor road leading to more than 2km downstream. This gantry also does not give indication of the forthcoming entrance to Route 3 United Kingdom United Kingdom US, Germany, Netherlands France Germany General Approach

• There is much room to improve signing towards the SRN. • The use of symbols alone could be beneficial at upstream approaches. • It is necessary to better define and possibly simplify the relationship of the various entities:

SRN routes CHT symbols Expressways (green panels) Destination names and hierarchy

• Use of subsidiary sign to overcome problem of too much information. • Any new design rules shall not further complicate the system. Issues to be resolved

• How can we maintain consistency for different sign formats and graphical presentations

• Cross-harbour tunnel symbols Other Issues of Directional Signing for the SRN

• Obscuring/Clutter

• Lane drop signing not provided

• Lack of signing for successive junctions

• Inadequacy of advance distance

• Sign face details – graphics, colours, destination choices etc Obscuring Lane drop signing not provided Lane drop signing A 9 B,C
