Abstract Japan is suffering from the problem of an ageing society. In Kitakyushu city more than a quarter of people are aged above 65 years. The roads in this region are narrow with steep gradient and vulnerable roadbed. A big ratio of elderly people are living on their own. These characteristics make driving unsuitable. The problem is magnified by infrequent public transportation. A need-assessment survey for an autonomous vehicle at a community event suggested the applicability of small electric vehicle Toyota COMS. The vehicle is then equipped with features like automatic driving and platooning. The autonomous drive system is built to develop an intelligent transport system (ITS) using various sensors and actuators. Stereo camera and ultrasonic sensors were used to get a judgment of obstacle. Google earth and GPS were used to generate the target path using the Bezier curve method and optimized route is chosen.

In 1966, Congress boldly reshaped the American approach to road safety and thereby established the United States as the worldwide leader in vehicle safety. Congressional action led to the establishment of the Department of Transportation, the National Highway Traffic Safety Administration (NHTSA), Federal Motor Vehicle Safety Standards, and the motor-vehicle safety defects and recall system. However, the safety environment that gave rise to these responses has evolved substantially. Fifty years later, the United States is unable to properly regulate rapidly advancing safety technologies, and the recall system is wholly unsuited to ensuring the safety of software-driven systems. Congress must act to update the road safety system in order to enable the United States to meet the challenges and seize the opportunities of the new transportation era.

Abstract An experimental study on reducing aerodynamic drag and improving fuel economy through vehicle platooning was conducted to develop an Intelligent Transport System (ITS) with good fuel economy of the entire vehicle-based transportation society. The objectives of the present study are to achieve a simple and quick approach to estimating the aerodynamic drag reduction rates of vehicle platooning. This paper reports the prediction formula, including the conditions of various types of vehicles in multiple-vehicle platooning, based on the power law of a free turbulent axisymmetric wake and on-road experimental results. Note, the prediction formula in this study does not fully include the effect of various type of wake deficit patterns due to rear shape of vehicle and atmospheric wind. Therefore, continuous study is needed to examine the applicable limit.

Abstract This study presents the design and development of a vehicle platform with intelligent sensors that has the capabilities to drive independently and cooperatively on roads. An integrated active safety system has been designed to optimize the human senses using ultrasonic infrared sensors and transmitter/receiver modules, to increase the human vision, feel and communication for increased road safety, lower congestion rates, and decrease CO2 emissions. Ultrasonic sensors mounted on the platform, emitted longitudinal 40 kHz waves and received echoes of these sound waves when an object was within its direction. The duration was converted to a distance measurement to detect obstacles as well as using distance measurement threshold values to implement adaptive cruise control. Infrared sensors equipped with an IR LED and a bipolar transistor detected a change in light intensity to identify road lanes.

Abstract Our society is faced with the serious problems such as aging population growth, environmental pollution and limited energy resource issues. As a means to address these issues, we are developing new mobility vehicles designed to support short-distance trips in urban settings. These mobility vehicles are intended for use in pedestrian areas inside buildings as well as outside, including public roads. In order to ensure safe and convenient operation for both pedestrians and mobility users, we conducted a risk assessment of mobility vehicles in pedestrian areas, and then developed a feature to autonomously limit the speed according to their surrounding conditions. This report discusses the utility of these mobility vehicles with the safety functions based on the fully conducted risk assessment, collision test and performance evaluation in public roads.

Abstract In the coming half-century, the global transport industry is expected to be affected by two technological revolutions - the first will start upon admission of autonomous vehicles to public roads, while the second will finalize a complete removal of manned vehicles away from them. As a result of the above revolutionary shocks, several major changes are anticipated: the modification of whole paradigm of ground vehicles; introduction of new business models in the transport sector, as well as new vehicle ownership forms; transition to technologies of collective and cooperative management and synchronized parrying the dangerous traffic collisions.

Abstract Automation of vehicles can be expected to improve safety, comfort and efficiency, and is being developed in various countries. Introduction of automated driving can be ranked from 0 to 5 (0: no automation, 1: driver assistance, 2: partial automation, 3: conditional automation, 4: high automation, 5: full automation). Currently, feasible automation levels are considered to be levels 2 or 3, and human manual take-over from the automated system is needed when the automated system exceeds these levels. In this situation, time required for take-over is an important issue. This study focuses on describing driving simulator experimental results of time required for take-over. The experimental scenario is that the automated system finds an object ahead during automated driving on the highway, and issues a take-over request to the driver. The subject driver can be in the following driver situations: hands-on or hands-off the steering, and strong or weak distractions.

Abstract This paper reports an effort to improve plan of vehicle trajectory using an approach with rapidly-exploring random trees (RRT), which has been widely adopted in the prior art for complex and dynamic traffic environment. Design and implement of an integrated threat assessment is presented that evaluates threats of the trajectory. A node and trajectory evaluation index was introduced into the proposed RRT algorithm to connect an appropriate node and select the best trajectory. The contribution of this paper is on the threat assessment that takes into account not only obstacle avoidance but also stability. The simulation is conducted and the results show that the proposed method works as expected and is valid and effective.

Abstract This paper describes the Common Automobile Program (CAP) that can be implemented to improve mass transportation. CAP is the use of automated electric vehicles using smart navigation and control technologies to improve mass transportation. In CAP, common vehicles are used by different passengers, thus, reducing the on-road traffic and also the parking space required. Various low-cost stations are to be built along specified paths and the vehicle can be used at the convenience of the commuter. Currently, buses and trains require the passengers to wait at the station and a significant amount of time is spent at intermediate stops. The vehicle in CAP runs directly from origin to destination and also eliminates the waiting time at stations. Passengers do not wait for vehicles; instead vehicles wait for the passengers. The journey starts as the passenger enters the station and selects the destination.

Abstract Current vehicles, especially the electric ones, are complex mechatronic devices. The pickup vehicles of small sizes are currently used in transport considerably. They often operate within a repeating scheme of a limited variety of tracks and larger fleets. Thanks to mechatronic design of vehicles and their components and availability of high capacity data connection with computational centers (clouds), there are many means to optimize their performance, both by planning prior the trip and recalculations during the route. Although many aspects of this opportunity were already addressed, the paper shows an approach developed to further increase the range of e-vehicle operation. It is based on prior information about the route profile, traffic density, road conditions, past behaviour, mathematical models of the route, vehicle and dynamic optimization.

Tesla engineers have previously talked about a potential mixed-materials strategy as they move down the retail-price ladder. The prospect of an aluminum-intensive Model 3 raises the question of how profitable a $35,000 EV will be when it carries 60-80% of the battery capacity of the basic $71,200 Model S 70.
