Analysis of Field Operational Test Data Obtained in Haneda Airport Area

Abstract

The field operational tests (FOTs) carried out in the Haneda Airport area used automated driving support infrastructure such as magnetic markers, bus lanes, traffic signal information, public transportation priority systems (PTPS), and the like to verify whether buses equipped with automated driving technology could achieve a stable and regular service on a circular bus route on public roads in the vicinity of Haneda Airport and realize precise arrival (docking) control at bus stops. Automated driving tests consisting of a total of 322 laps of the circular bus route were carried out, and it was confirmed that a stable and regular service by automated driving could be achieved under a mixed traffic environment. In addition, approximately 80% of manual interventions in the tests were to avoid parked vehicles or because the test vehicle came too close to the stop line of the oncoming lane when turning left. It was also confirmed that the use of PTPS helped to realize a more punctual service with stable travel times. The FOTs also confirmed that bus lanes helped to improve the continuity of automated driving. However, it was found that the resulting conflicts with ordinary vehicles would necessitate publicity and educational activities, as well as campaigns to encourage people to follow the rules of bus lanes. At bus stops, a total of 416 automated driving docking control tests were carried out, confirming the feasibility of highly reproducible docking controls to a standard deviation of less than 10 mm through the use of magnetic markers.
