Module 4 – Signs, Signals & Pavement Markings 1. Explain the purpose of the following in complete sentence answers, using proper spelling and grammar: A. Broken yellow lines indicate: Broken yellow lines indecate that you can pass on a two-way road. B. Yellow lines (broken or solid) indicate what type of traffic flow: Yellow lines indicate opposite traffic flow. C.

In the space to the right, draw or describe the symbol that prohibits some type of action. For example, “No U-turn” Red Circle with a Red Slash 2. a) On the line below each of the diagrams put a (1) if it is a regulatory sign, a (2) if it is a warning sign, or a (3) if it is a guide or informational sign 2. b) Complete the diagrams with a message of how that sign might read along a road and list the color on the line below. Give the meaning for each line, roadway marking described below 3. Solid White Line: marks right edge of roadway, do not cross 4.

If you're going in a specific direction, you will always go in that direction unless something happens to you. 2. “The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.” The second law shows that if you apply the same amount of force on two objects which have different masses, you will get different accelerations. The bigger the mass of an object, the less effect the force applied has on it.
Mass can also be defined as how much inertia something has. The second law of motion says: “A net force acting on an object causes
Longitudinal wave The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium. For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport. Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. As the vibrating string moves in the forward direction, it begins to push upon surrounding air molecules, moving them to the right towards their nearest neighbor.
A vector is a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another. A vector is a measure which has both magnitude and direction. For example vectors include displacement, velocity, acceleration, and force. To fully describe one of these vector quantities, you need to tell both the magnitude and the direction. For instance, if the velocity of an object were said to be 25 m/s, then the description of the object's velocity is incomplete; the object could be moving 25 m/s south, or 25 m/s north or 25 m/s southeast.
Since acceleration is a vector quantity it has magnitude and direction [3]. Uniformly accelerated movement (UAM) is movement that always has the same acceleration, meaning that it has a constant equal force. An object with a constant acceleration should not be confused with an object with a constant velocity; an object with a constant velocity is not accelerating. The perfect example of constant force is gravity (g Earth = 9.81 m/s2), which is the force of attraction between all masses in the universe, and in this cases specially the attraction of the earth's mass for bodies near its surface [4]. If an object is held motionless in a uniform gravitational field it will fall in a constant acceleration, this means that every second that the object falls its velocity will
It is different from the classical vehicle routing problem in terms of constraints. In this problem, real time traffic data is collected from various cameras mounted on various places on the roads, polls and buildings. The data is processed at the central server and instructions are sent back to vehicles giving better option available(less traffic routes) as per their current traffic. This problem is different from vehicle routing problem, in that, all input is known beforehand and vehicle routes do not change once they are in execution. But, in this real time data is processed and dynamically route is calculated.
The velocity of an object is the rate of change of its position. Velocity includes not only the magnitude of that rate of change but also the direction. The acceleration is the direction and rate of change of the velocity of the object. These relationships can be represented graphically. The velocity can be obtained by finding the slope of the graph of position as a function of time.
