Concept explainers

Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.

Assume that drivers in fact follow the rule of the road of keeping a gap of one car length (L) for each 10-mi/h increment of speed. Assuming a car length of 20 ft, develop the equations of stream flow and draw the u-k, q-u, and q-k diagrams. Discuss the results.
Traffic on a freeway gives a Greenshield's traffic flow relationship expressed as: Q = 60k-0.16667k? At 10AM, an accident occurs 4 km downstream of an access ramp. The vehicles pull onto the shoulder of the roadway, but traffic passing the accident area slows to 10 kph as drivers survey the damage on the side of the road. A patrol car enters the freeway via access ramp, also at 10AM. Upon entering the freeway, the patrol car notes that traffic on the freeway is moving along at about 40 kph. Determine the following: 1. Capacity flow of the highway 2. Traffic shockwave created by the road accident 3. Time in AM the patrol car will reach the accident zone 4.

Quest... In a three-phase signal system design for a four- leg intersection, the critical flow ratios for each phase are 0.18, 0.32, and 0.22. The total loss time in each of the phases is 2 s. As per Webster's formula, find the optimal cycle length.
A traffic stream is moving at a steady state when entering a mountain grade. Upon entering the grade, the speed, density and flow are 72 km/h, 25 veh/km and 1800 veh/hr respectively. On the grade, a truck drops to a speed of 15 km/h causing traffic to bunch up to a density of 85 veh/km. When the truck pulls over, traffic accelerates to the maximum flow until steady state flow conditions resume. Calculate (a) the flow of traffic behind the truck on the mountain grade (b) the jam density and free flow speed for this road (c) the density and speed when traffic resumes a steady state flow (d) the maximum flow
The speed-density relationship in a mid-block section of a highway follows the Greenshield's model. If the free flow speed is V, and the jam density is k, the maximum flow observed on this section is (b) v,k, (d) V.k v,k (c) Vik
Plz, solve this problem. Transportation Engineering-2 A four-lane highway (2 lanes in each direction) with 3.65m lanes has a horizontal curve designed for a 380 m centerline radius, and a 110 km/hr design speed. The grade is level. Use a driver perception reaction time of 2.5 sec and a vehicle deceleration rate of 3.4 m/sec2. Determine the closest distance any roadside object may be placed to the centerline of the inside lane of the roadway.(note: Do not round any value. Use calculated values).
