The purpose of this study was to find new methods and technologies which could help develop better, safer and easier ways to measure cycling data. The result of this literature study is divided into equipment detecting cycles in order to control traffic signals, and equipment used to measure cycle flow. There is also a section that focuses on comparisons between different measurement equipment and another on how new technologies can be used for other benefits for cyclists. Some of the studies referred to, have focused on how the equipment should be used and adjusted to provide the best measurement results. This problem seems to be very important for further research. For the future one can hope that the cycle, the cycle computer, or possibly even the cycle helmet will be equipped with new technology. Technology would not only allow measurement of the cycle flows and control of traffic signals, but would also provide an information link to and from the cyclists. It may also even make it possible to trace a stolen cycle.
