The document discusses the build-operate-transfer (BOT) model for the Vadodara Halol Toll Road Project in Gujarat, India. Under the BOT model, a private entity receives a concession to finance, design, construct, and operate a toll road for 30 years, after which it transfers the road back to the government. The project involved upgrading a state highway to a four-lane expressway under a public-private partnership between the state government and IL&FS. While the project was completed on time and under budget, actual traffic levels fell short of projections, leading to financial difficulties for the private operator.
