... 5Overview of Wider Transportation Benefits Defining the Concept of Wider Benefits What are wider benefits? Traditionally, benefit–cost analyses for transportation projects in North America have focused on measurement of transportation system efficiency, represented in terms of direct effects on travel time, vehicle operating cost, and collision incident cost -- collectively referred to as traveler or "user" benefits.

... 6area from which a business can reasonably expect to draw customers and workers. These effects are often represented as changes in the effective size or the effective density of the customer market and labor market available to the firm.

... 10 literature of empirical research on this subject, which is discussed later in this chapter. Table 2.2 shows the classes of wider transportation effects covered in this report and the most common breakdown of trip purposes.

... 11 Once the various positive and negative factors have been assigned rating scores, they are entered into a project scorecard table along with ratings for other factors that matter for prioritizing projects, such as travel system efficiency and environmental and community impacts. Table 2.4 shows examples of rating factors related to wider transportation impacts that are already being used by four states for project ranking and selection.

... 12 the regional economic impact models count changes in business travel cost as reductions in the cost of production, while changes in household costs are considered shifts in household budget or spending patterns. Third, it counts business attraction and inward investment effects on economic growth, including effects of cost competitiveness changes that lead to spatial and business sector shifts in trade flows, investment flows, and prices.
