Response Surveys

Response meter surveys will be conducted in accordance with the latest revision of Transfund's Road Condition Roughness Manual.

The survey method using the response meter can be used on sealed or unsealed roads and in most weather conditions.

Road Info Ltd operates one laser vehicle that is also fitted with a response meter. This enables the operator to calibrate the response meter directly against the laser equipment at any time required.

At the commencement of the survey a representative site of approximately one kilometre shall be surveyed and the results processed. The unit will be checked at daily intervals for both distance and roughness counts. Should the resultant figures vary by more than 3% standard deviation from the original run then the cause of the deviation shall be ascertained and corrective action taken. Results of the above runs are reported to the client as part of the quality assurance report at the conclusion of the survey.

During the survey our operators ensure that the equipment is functioning normally by monitoring the computer readouts.

The quality of the accumulated data is checked on a regular basis using a data integrity program which looks for anomalies in the raw data. This alerts the operators to any potential problems of data quality and enables us to retest as soon as practical.

The verification process will also allow our experienced operators to be certain that all roads necessary have been surveyed in full before leaving the district.

Our office staff then completes the processing by using our specifically developed in-house software to fit the data into the RAMM data base, which can be uploaded electronically to CJN Technology’s hosting service.

Finally a written report is forwarded to the roading engineer/ project manager stating:

- The number of rows uploaded,

- The number of kilometres surveyed,

- Specific operator notes per road surveyed,

- Notes about quality assurance,
