  • Abstract:
    It is frequently assumed that an Automated Highway System (AHS) will require lanes exclusively dedicated to automated operation, and that operation in mixed traffic is either not safe or not practical. Since these assumptions preclude automated vehicles from sharing existing lanes with manual traffic, they imply the introduction of an AHS will require either new construction or diversion of existing lanes from their current use, and at a time when there are likely to be few vehicles equipped to use them. If these assumptions are indeed valid constraints, they make the initial deployment step a very steep one. First, there would be the need to justify investment in infrastructure well before there are compensating benefits. At least as serious is the prospect of the heat that will be generated by drivers who must continue to endure the unrelieved, or possibly worsened, congestion in full view of this underutilized toad space. An Automated Highway System is much more likely to be brought into being if the operational concept and the system that supports it are compatible with a gradual and nondisruptive introduction into the existing freeway system operational environment. Here we describe and broadly analyze an evolutionary scenario in which the vehicles equipped for automated operation are assumed to be capable of safely operating in mixed traffic with unequipped, manually operated vehicles. We assume a gradual evolution of incremental change, both in the scope and capability of the automated features, and in the vehicle fleet as new, equipped vehicles replace old ones. We believe the scenario described is both technically and operationally feasible and offers the prospect of an essentially seamless and nondisruptive path to an Automated Highway System - and beyond. In devising this scenario, we have attempted to meet two primary criteria: · The evolution of the system should be technically sensible, with each step building upon previous steps. We do not want Step #8 to obsolete Steps #2 and #3. · At each step in deployment, there should be reasonable correlation in time and degree between costs and benefits. Investment, either by individuals or by political bodies, is only motivated by perceived benefit.
