An Active Safety System for Low-Speed Bus Braking Assistance

Abstract

Abstract-Buses and coaches are massive Passenger Transportation Systems (PTS), because they represent more than half of land PTS in the European Union. Despite of that, bus accident figures are lower than other means of transport, but its size and weight increase the severity of accidents in which buses are involved, even at low speed. In urban scenarios, turnings and manoeuvres around bus stops are the main causes of accidents, mostly due to low visibility, blind spots or driver's distractions. Therefore, there is an increasing interest in developing driving assistance systems to avoid these situations, among others. However, even though there are some solutions on the market, they are not meant to work in urban areas at low speed and with the sole purpose of preventing collisions with pedestrians. In this sense, the paper proposes an active safety system for buses in manoeuvres at low speed. The safety system consists of haptic feedback devices together with collision avoidance and risk evaluation systems based on detected people nearby the bus. The performance of the active safety system has been validated in a simulated urban scenario. Our results show that driver's reaction time is reduced and time to collision increased due to the proposed low-speed active safety system. In particular, it is shown that there is a reduction in the number of high risk cases and collisions, which implies a considerable improvement in safety terms. In addition to this, a brief discussion about current regulations for innovative safety systems on a real vehicles is carried out.

Combining haptics and inertial motion capture to enhance remote control of a dual-arm robot

“…Force feedback has also been used to warn the drivers of a potential risk in advanced driver assistance systems. To avoid collisions, a haptic device can be added either in the pedals [35] or in both pedals and steering wheel [36,37] to interact with the driver.…”

Adaptive Advanced Emergency Braking on Combined Road Friction Coefficients

“…AEBS has been also adopted to the heavy weather conditions, such as the asphalt covered in ice and snow [4]. By taking in consideration to city traffic, pedestrians, bicycle drivers and changing weather conditions, AEBS becomes one of the significant driver assistant systems to prevent rear-end collisions [5][6][7][8][9][10][11][12]. Although, these cases were supported with suitable controlling technologies, an adaptive AEBS is required in case of a rapid decrease in the road friction coefficient during braking.…”

Blind-Spot Collision Detection System for Commercial Vehicles Using Multi Deep CNN Architecture

“…Improvements to heavy vehicle and bus safety have been initiated by many countries through the installation of additional mirrors. Yet, there are still some blind-spot areas where drivers cannot see other road users [21,22]. In addition, buses may have many passengers on board.…”
