The Role of Micro-simulation in Evaluating Intelligent Transportation Systems ApplicationsWhy not Place Total Reliance on Infrastructure ExpansionIt would be impractical to seek to improve the welfare of consumers by just expanding the road networks. For instance there are other dynamics and factors such as demand reduction, mobility issues and considering the traffic perspectives and insights. This is to say that there improving the road network or its expansion may not be outright solution for the question of congestion. Rather, there are aspects of maintaining an acceptable and manageable level of service to the road users such as the drivers. Similarly, there are certain setbacks which may adversely affect the prospects of road expansion endeavors such as the high financial cost that would be incurred, the induced traffic phenomenon and the inadequacy of space to undertake the expansion (Khan, Armstrong, amp. Munir, 2006).Why Macroscopic Tools are not considered for Effective Testing of Various ScenariosThe high capacity manual that is a microscopic tool was not used in this aspect and respect because of the prospects of the concerned dynamics such as factoring in travel information. Secondly there is the need and urge to leave an allowance or a space of improvement such as communication systems and lines which in all aspects and fairness constitute a real part of the human life (Khan, Armstrong, amp. Munir, 2006). This is to say that there are certain aspects and things that form part of the human life but are not easily represented during simulation studies such as aerial communication lines and other related aspects.Why Base Case Gets Included in Effective Studies Base case is usually used to cover and acts as the irreducible minimum for all the dynamics that may occur or accrue ion the course of the actualization of the project. For instance, there are chances that the communications lines along the simulated road models would be erected are. Thus, the base case is critical and beneficial because it would bear in mind the structural changes that are highly likely to be pursued in the due course of time (Khan, Armstrong, amp. Munir, 2006). Similarly, base case is also techniques that cover in and factors all the things and issues that are considered as eventualities in human life and aspect such as an accident.Why Adding New Capacity on Highway 417 is Ineffective This stems from the fact that highway 417 was expanded from a four lane to a six lane Highway and road network. This was done and factored in due to the comparison that was done and completed on the chances of expanding it relative to the traditional building capacity projects. For instance, during the simulation, it was postulated that an accident in this Highway may lead to a closure for close to twenty minutes before the spill heavy traffic spills over to the other lanes (Khan, Armstrong, amp. Munir, 2006). This adds new capacity to highway 417 may to be as effective.Comparing the Effectiveness of Freeway-arterial Integrated Corridors and Ramp MasteringRamp metering seems to be more effective as compared to the free-arterial integrated corridors due to the fact that the former may be most effective over a short period of time. This is the reason as to why the ramp-tempering technique and approach may be considered to be more beneficial (Khan, Armstrong, amp. Munir, 2006). Similarly, the ramp tempering approach would be critical to ensure that the travel demand is reduced, as the traffic operations and the efficiency of the transport network is subsequently bettered. Thus, ramp metering technique may be more beneficial because it would be relevantly effective over a longer period of time.ReferenceKhan, A.M., Armstrong, J., amp. Munir, A. (2006).
