First of all, what is transport modeling? Transport modeling is a technology that enables builders to predict the outcome of a project or situation based on given, programmed factors and inputs. In the case of creating new routes, transport modeling focuses specifically on the simulation of road networks based on patterns of vehicle movement, traffic flow and queues, pedestrian and commuter actions and preferences, and number of vehicles. Transport modeling can work through simulation, or virtual recreation, of the actual processes and systems for a real time view of possible scenarios without having to disrupt ongoing processes (which could cause major inconveniences and losses, specially if you're dealing with key road networks and traffic). Other modeling systems are used today with some as basic as paper modeling, but very few could compete with virtual transport modeling, due to the many benefits it offers.
Here are some more detailed ways that transport modeling could help when creating new routes:
It helps in maximizing efficiency. If a builder is planning a new regional road network, for example, he could use transport modeling to make sure that the most efficient routes will be built. Other factors that a transport modeling system could determine include the best transport boundary to balance population needs and competent management of resources; how to best maintain ecological balance; and a road network lay-out for easy access to common destinations. Multimodal transport modeling is also commonly used to assess outcome based on factors that are simultaneously at play. With multimodal transport modeling, a builder could program in a possible range of scenarios and conditions; the transport model could compute how these factors could interact and what factors could come together to bring about the best possible outcome.
It exposes potential risks. Transport modeling in more specialized branches, such as in aerospace transport, deals with radiation transport modeling that would help scientists predict radiation risks astronauts could possibly face during long-term, deep-space missions. The results of these studies enable scientists to design adequate protection for astronauts who would go on such missions. Other risks that could be exposed using transport model systems include assessing the risk of groundwater contamination because of new commercial and mass transport routes. Hydrologists could use groundwater modeling to predict future water conditions based on the water transport dynamic and possible pollution emissions from vehicles.
It can cut costs. Through the adequate and efficient planning that transport modeling could provide, mistakes and wastefulness could be avoided early on in the planning and evaluation stage. Routes and road networks, as well as other mass transport schemes including railways and airports, could be constructed in the most cost-efficient manner. Reconstruction efforts (which would elevate costs) because of mistakes in planning would be avoided.
- It helps in planning for further improvement. Transport modeling could help in the assessment of the efficiency of current road routes, as they enable analysts to effectively isolate different factors, so they could thoroughly examine how heavily each factor affects the situation. Once they have pinpointed the specific root or roots of the traffic problem, then they would be able to start making plans to address this problem.
