Quality of road data measurements can be adversely affected by a mobile laboratory directly linked to the test vehicle or alternatively by the weight of the in-vehicle test equipment. Compact, low powermicro-electronic systems provide the means of overcoming these limitations. This paper outlines two complementary techniques, designed specifically to improve road load data collection and analysis efficiency. System choice however must be matched to the data application. Part 1 of the paper deals with a 24 channel system centred around a light-weight in-vehicle microcomputer, enabling data reduction whilst the test is in progress. Designed to accommodate a range of 'level count' routines, this system is capable of very quick data turn round times. Part 2 outlines a 32 channel PCM/tape encoded system to collect raw data. It can be used in-vehicle or with short range telemetry to a chase vehicle for more extensive tests. The data can be subjected to any evaluation procedure.
