Three Layer Strategy

Three Layer Framework

The concept of the three-layered approach is to deliver progressive messaging to drivers.  It is suggested that some drivers transit through the heart of the village without realising it and they do so at excessive speeds. Irrespective of which direction the driver enters the village, the three-layered strategy delivers consistency and familiarity to drivers that should make them more aware of their surroundings than is currently the case.  Irrespective of which direction the driver enters the village, the three-layered framework delivers consistency and familiarity to drivers in an attempt to make them more aware that they are in the village area.

The location of the three-layers

  • Is not defined by existing signage or existing boundaries;

  • Will be positioned where they have maximum effectiveness;

  • Will inform the location of future traffic calming measures;

  • Will recommend traffic calming measures favoured by the village community.

Outer Layer : Informing
Low Level Intensity

  • The outer layer of the model is to inform the driver that he is entering the village area and that speed restrictions are in place.

  • Irrespective from which direction the driver enters the village area; the same consistent message is given.

  • To ensure the best possible chance of the driver absorbing the message, it should be conveyed to affect as many different stimulus as possible: seeing, feeling and doing.

Middle Layer : Reinforcement

Medium Level Intensity

As drivers continue further into the village area, and get closer to the village centre, the middle layer is to reinforce the message that was given at the outer layer.

  • Measures adopted should consider seeing, feeling and doing.

  • To improve the chances of success, measures should not be a repeat of the same measures at the outer level.

  • For example, if a gate with a speed sign and a contrast in the road surface marks the outer layer, then the middle layer should be marked by something different such as a vehicle activated sign or a single lane chicane.

Inner Layer : Imposing Sanctions
High Level Intensity

The inner layer changes the messaging from informing to enforcement.

  • The driver should be faced with higher level of intensity of measures;

  • Measures may embrace any aspects of the following; Rumble Strips, Speed Bumps, Cameras, Flashing Beacon Crossing, or potentially a one -way system.

  • Being creative is imperative to give the village more of a feel that it has a centre and that it is owned by the village and not by traffic.
