Traffic forecasts are used for several key purposes in transportation policy, planning, and engineering: to calculate the capacity of infrastructure, e.g., how many lanes a bridge should have; to estimate the financial and social viability of projects, e.g., using cost–benefit analysis and social impact assessment; and to calculate ...
If the assessment is favourable, and the proposed policy is enacted—after a suitable length of time for the policy to gain traction—it might be followed by an impact evaluation; ideally, assessed impacts before the fact and evaluated impacts after the fact are not wildly divergent. In some cases, impact becomes politicized due to a change ...
Intersection Capacity Utilization method is most often found in a traffic impact study (TIS). TIS is prepared mostly by city officials and/or private civil consulting firms. The importance of TIS is often seen when there is a new building being constructed in a downtown area.
The traffic load near large cities may show dramatic cyclical changes induced by weekend tourism, and this could induce cyclical changes in the activity patterns of birds. [49] Road implantation may also lead birds to avoid certain sites, as they are seen as being less habitable (because of increases in noise and chemical pollution).
Trip generation is the first step in the conventional four-step transportation forecasting process used for forecasting travel demands. It predicts the number of trips originating in or destined for a particular traffic analysis zone (TAZ). [1]
The health and environmental impact of transport is significant because transport burns most of the world's petroleum. This causes illness and deaths from air pollution , including nitrous oxides and particulates , and is a significant cause of climate change through emission of carbon dioxide .

Other authors make a distinction between "impact evaluation" and "impact assessment." "Impact evaluation" uses empirical techniques to estimate the effects of interventions and their statistical significance, whereas "impact assessment" includes a broader set of methods, including structural simulations and other approaches that cannot test for ...
