- What do you think could be a possible solution to traffic congestion in Metro Manila in general? Discuss briefly your suggested solutionPropose your OWN solution/ action on how to resolve traffic congestion. Explain with specific details, and add figure or pictures if necesarry.List six transportation simulation models or software systems described in the Highway Capacity Manual 2000 or elsewhere and elaborate on five (5) of these models/software systems.
- 1. A study of freeway flow at a given site has yielded a relationship speed-density calibrated as follows: S = 57,5(1 - 0,008 D) For this relationship, specify: (a) free flow velocity, (b) congestion density, (c) velocity-flow relationship (d) flow density relationship, and (e) capacity. 2. Answer all the questions in Problem 1 for the calibrated density-velocity relationship the following: S = 61.2e^-0015Da) What is traffic management? b) Enumerate and explain four (4) types of traffic management strategies that can be employed by road agencies in Ghana.Question 2 Because the new travel time rate (TTR) from the additional traffic (e.g., 300vph) exceeds the minimum acceptable local standard of 2.0 min/mile, it is proposed to increase the road capacity by 900vph/lane by adding one lane in each direction. Calculate the new travel time rate and traffic volume using: a. The traditional method of traffic impact analysis, and b. The above-mentioned pivot point analysis method. c. Compare the results of the two methods and comment on their significance.
