GB 25280-2016Road traffic signal controller (English PDF)

4.1 Classification

4.1.1 functional classification Road traffic signal controller (hereinafter, simply referred to as signal) divided by control signals A, B, C three categories (Table 1). Table 1 signal classification categories and basic control functions Reference signal type control signal A Class B Class C signal signal 1 yellow flashing control - - - Over 2 - - - Control period

3 Manual control - - - Induction - - Control 4 5 cable without coordinating control - - 6 networking control - - - 7 a single point of control to optimize - - 8 bus signal priority - 9 emergency priority -

Note. "-" should have the function of, "-" have appropriate functions.

4.1.2 Classification by installation environment Signal according to the installation environment can be divided into indoor and outdoor units. An indoor unit placed in the indoor or outdoor cabinet work and other non-open-air environment, the outdoor unit can be directly installed in the open air work.

4.1.3 by using a form of classification Signal by the use forms can be divided into fixed and mobile signal signal.

4.2 Model Rules for the Signal models include the functional classification, installation environment, use the form, working temperature levels, corporate self-encoded, shown in Figure 1.
