"The Transportation Services Indexes (TSI) are leading indicators of economic cycles. When the accelerations and decelera­tions of the freight TSI are compared to the growth cycles of the economy, the freight measure leads by an average of approximately four months,” BTS said. “The passenger TSI exhibits fewer turning points, which were then identified as leading the business cycles of re­cession and expansion, also by approximately four months. As 71% of America's freight is moved on trucks, companies foreseeing needing fewer trucks is typically an omen of an economic downturn: If manufacturers are producing less and people are buying less, there's less of a need to move goods." - Bureau of Transportation Statistics
