The present invention discloses a method of infrared spectrometric measurement of tunnel gas employing a gas measurement system including a gas collection unit, a gas analysis unit and a positioning indication unit for measuring the gas in the tunnel. The method performs sequential steps of installing the gas measurement system, starting the positioning indication unit for positioning one of the detection regions in the tunnel space, sampling the gas in the detection region through the gas collection unit, analyzing the gas by the gas analysis unit, generating a gas analysis result, and determining whether all of the detection regions are completed. With the newly designed gas collection unit in collocation with the gas analysis unit and the positioning indication unit, the method of the present invention does not only fast install the whole gas measurement system, but also well understands all preliminary information related to the harmful gas in the tunnel like sort and concentration, thereby instantly taking correct measures.

In some embodiments, data from a vehicle-borne gas leak detection survey are used to generate an aggregate leak indication search area (LISA) indicator for a plurality of leak indications (measurement peaks) characterizing a single leak or localized set of leaks. A clustering algorithm (e.g. Markov, DBScan) may be used to group a set of indications into a cluster characterizing the leak. Leak indications may be pre-filtered for quality control before assignment to a cluster according to a number of parameters including background gas level, inter-peak distance, peak shape, wind speed, wind direction and/or variability, vehicle speed and/or acceleration, and/or a lower detection threshold for leak flow rate.
