This report outlines some examples of current research at TRRL, which are designed to exploit the possibilities offered by advances in the on-line application of computers and in microelectronics: scoot (split, cycle and off-set optimisation technique) is a traffic responsive system based on the concept of frequent but small modifications to timings stored within an on-line computer program; use of micro-processors for installing sophisticated control strategies; automatic detection of motorway incidents by means of inductive loop detectors associated with an on-line computer programmed with appropriate logarithms (HIOCC and PATREC are 2 algorithms devised at TRRL); automatic route guidance vehicle- or road-based systems. Mention is also made of the application of micro-electronic techniques to the collection of traffic data by means of several sensors linked with a small on-site computer. (TRRL)
