Formatted abstract

Local Area Traffic Management (LATM) is one of the most contentious public issues in the Transportation Engineering field. At present there are few clear guidelines established relating to LATM procedures  

A basic guide to LATM planning and implementation has been published by Austroads giving an indication of the steps taken in most LATM schemes. Of the steps discussed in this and other documents the following will be developed throughout this study:

• problem identification  

• setting goals for improvement

• monitoring of effectiveness   

This study aims to outline the current practices relating to LATM Squeeze Point installations in Caboolture Shire Council, the relative effectiveness of the devices and schemes, and the use of this data for problem identification.  

The Squeeze Point device was selected as this is the most commonly installed device in Caboolture Shire, but the effectiveness of installed devices had yet to be determined.  

The determination of the effectiveness of this device involved the collection of traffic data by means of Metrocount pneumatic tube traffic logger and associated software at the various installations. The new post installation data sets were then correlated to those available from pre installation surveys conducted in a similar manner and analysed to determine the impact on the traffic and relative effectiveness. The analysis of the data sets used parameters such as:

• Annual average daily traffic volume

• 85th percentile and average speeds

• 15 km/h pace and percentage in pace  

• Percentage of heavy vehicles

• Crash data   

From this analysis it was determined that the squeeze point as a device is effective in reducing traffic speeds at the device. The analysis of several LATM schemes indicated that on average, the squeeze point scheme would reduce or stabilise traffic speeds to acceptable operational levels for a 60 km/h speed environment with the potential for reducing traffic volume also.  

This data was then used to form a point allocation system, which then was applied to the Caboolture Shire Local and District Collector streets in conjunction with published action warrants as a preliminary tool for identifying problem areas in the Shire and the associated action to take.  

The following study outlines the effectiveness of the Squeeze Point device and installed schemes, and shows how parameters may be applied to form a preliminary problem identification tool.  

These results are aimed to aid Caboolture Shire Council practitioners in maintaining the planning and development of effective LATM Squeeze Point Schemes in a consistent, objective and timely manner.
