3.1 Site Selection
Site selection varies with the application in which the radar is being used. However, thefollowingguidelinesshouldgenerallybeadheredto:
i) Chooseapositionwherethelineofsightfromtheradartothevehiclewillbeuninterrupted.Considerationshouldbegiven tohowthe locationmaydevelopwith time. Willanytrees grow directly in the line of vision? Is it likely that road traffic signs will be erected in a position that could obstruct the field of view?
ii) Theradarsignshouldbeinstalleddirectlyadjacenttothelaneofcarsitistargetingsince an interfering lane of traffic may cause inaccurate speed readings.
iii) The structure that the radar is mounted to should be stable and firm. Avoid structures thatarelikelytobeaffectedbywindorrain.

All above intensities are measured when LED’s are operated with 30% of maximum nominal current. Driving the LEDs with such a low current avoids aging effects. The design of the optical system with lenses that direct the LED light allows the sign to be optimally bright using only 30% of the power supply.
The Traffic Logix signs meet the highest requirement of NEMA TS4.1 and EN 12966 standards.

7. Datacollectionfeature
The SJT-02 device features a real time clock and a 64 kB non-volatile memory. The device counts the vehicles in specified time blocks and stores vehicle speed data in 17 categories, including a time stamp of the measurement period. The length of the time block is adjustable to 15 minutes, 30 minutes, or 1 hour. The speed categories are adjustable as well. You can choose the lower limit at which the sign will perform as well as the mile per hour increments at which information is calculated.
The capacity of the memory is 1524 blocks, corresponding to approximately 15 days at 15 minutes data collection periods or 60 days at 1 hour collection periods. If the memory is full, the next block of data replaces the oldest one so that the last 1524 blocks of data are available for reading at all times.
Any computer with installed PASTROS software can be used to access vehicle speed data via Bluetooth. For ease of sorting and analysis, the collected and downloaded data can be saved in several file formats (.dfs, .xls, .txt). The program also offers built in graph features that allow device parameters and operating modes to be customized.
For additional information about data collection and reporting, see the PASTROS software manual
