ABSTRACT
This chapter examines the intersection of the characteristics of road pricing schemes and the characteristics of Intelligent Transportation Systems (ITS) technologies to determine which ITS technologies could facilitate road pricing. It focuses on implementation of road pricing therefore recognizing that it is important to consider issues beyond efficient road pricing and pricing for financing. Implementation requires that attention also be paid to alternatives to the tolled facility, enforcement and public acceptance. The chapter examines cases where road pricing had been introduced and assessed their level of ITS integration; until recently, relatively minor. Two factors determine the sophistication of the ITS technology; the choice of objective function, revenue versus economically efficient pricing and the spatial dimension over which road pricing is applied. If revenue is the objective, a simple tolling structure such as cordon is sufficient, increasing level of ITS sophistication may improve efficiency and enforcement but at a cost.
