In this assignment, you will model the behavior of the control system that lowers and raises the gate where a road crosses a railway Far Near Train Passed Near Far Train Passed There are two semes, C. Sensor One (left) and Setter Two (right) respectively, telling the gate that a train is passed. This is a classical example of a real-time system, which we will only model very counsely here, assuming that there is only a single track with only one tra time and one gate in this assignment. However, a train could go in either direction. There are some specifications of the scenario following . When a sensor detects that a train passes, it will emit the signal "Train Passed" to the gate controller ystom, in order to make the gate start moving to the opposite direction to the previous one, c. from state up to stare down We assume that the gate needs between 20 and 30 seconds to be lowered to go from the state up to the state down or be raised to go from the state down to the state up) or to come down . The gae cannot be moved when the train is passing Otherwise, it will lead to tragedy Your task is to model the system by using correct UML station point out weaknesses of the system, and describe how the system could be improved to be more safe 3. Given a Traffic light control system with four driving ways and one le each side, provided safety considerations. Le be the safe distance for a car to press break pedal if a car breaks in a shorter distance that there is possibility to cross the red light. A car needs to stop before the sign of S2, S4, S6, S8 (see the figure below). In the following figure, the circle with dots representatie The dua tine antity the
