Revenues
The Oklahoma Turnpike Authority (OTA) in 1995 derived 98.8% of its $106 million in operating revenues from tolls. The balance of its operating revenues comes from concession contracts with businesses along turnpikes. Another source of income, called non-operating revenue, was $11.7 million interest earnings on $145.4 million in cash that is invested in a variety of instruments.
Toll revenue is impacted by two factors: toll rates and traffic.
