SWOT Analysis Of SCOOT
B.SCOOT
Greenough and Kelman proposed Split Cycle Offset Optimization Technique (SCOOT). It is an online signal timing optimizer developed in 1973 by the Transport Research Laboratory in the United Kingdom. SCOOT has been implemented into real-world application since 1979.It is designed for general application within a computerized Urban Traffic Control System. SCOOT implements a method of coordination that adjusts the signal timings frequently and make small increments to match the latest traffic situation. Data from vehicle detectors are analyzed by an on-line computer which contains programs that calculate traffic flows. The amount of green for each approach (Split), the time between adjacent signals (Offset), and the time allowed for all …show more content…
During installation, SCOOT requires the most time averaging about 630 hours per system. OPAC and SCATS required lower with averages of 340 hours and 205 hours respectively. In the training phase, SCATS averaged 60 hours of training while SCOOT averaged 38 hours and OPAC averaged 26 hours of training. The overall average of training was 41 hours. Regarding the hours of maintenance per week, the average maintenance effort for all the systems was nearly 10 hours per week. The OPAC average was slightly above the mean with a weekly maintenance average of 11 hours. SCOOT had highest average weekly hours of maintenance with 13 hours per week. SCATS averaged the lowest maintenance with 8 hours per week. Therefore for the overall maintenance, SCATS averaged less installation and fine tuning time and fewer maintenance hours per week compared to the other systems. To determine the reliability, let us take the downtime and system longevity into consideration. Downtime is calculated from the percentage of the system which would not be operational over any given time. OPAC with the highest downtime of 70% noted that the system suffered from several issues. Likely, this data trend shows that, the newer systems have worked out issues and are more reliable. SCOOT showed 10% -50% of downtime. Lastly, SCATS system showed more positive results compared to other systems with less than 5% downtime. But SCOOT had greater system longevity than SCATS
