Formed in 2006, RTEM Ltd is a small but highly focussed company dedicated to bringing the very latest technology to the road traffic monitoring sector. We provide a unique, low cost, innovative and high quality vehicle detection and classifier platform which may be used either as a traditional remote telemetry operated traffic counter or alternatively within a traffic signal controller to collate traffic data and provide bus priority from existing loops. The SP4 vehicle classifier unit also has an optional BlueTooth sensor to provide journey time data in addition to vehicle class data at a really cost effective price for the UK Local Authority market. The company's philosophy is to reduce hardware variations to an absolute minimum and to provide as much flexibility for that platform to undertake as many different traffic engineering tasks as possible. RTEM has a number of different firmwares, or "apps" for specific applications. All RTEM firmware is licence free and may be uploaded and changed as required. RTEM's unique approach to the traffic engineering market provides the opportunity for Local Authorities to add significant additional features and functions to their existing installed equipment register at an extremely low cost. The company is continuing to further develop this unique SP4 platform searching for new low cost effective ways of providing better and more accurate information for traffic engineers and transport planners.
