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.

This paper studies intelligent vehicle threat assessment aimed to improve trajectory planning for intelligent vehicles based on the random tree (RRT) approach, which has been widely adopted in the prior art for complex and dynamic traffic environment. The proposed RRT approach integrates the threat assessment in the trajectory planning and proves to be more efficient and effective compared to the hierarchical framework. 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.

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.

Automation of automobile can be expected to improve safety, comfort and efficiency, and developed in every countries. Automated driving is introducing according to automated levels 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 level is considered to be Level 2 or 3, and take-over from automated system to human manual driving is needed when the automated system overs at these levels. In this situation, required time for take-over is an important issue. This study focus on describing driving simulator experimental results of required time for take-over. The experimental scenario is that the automated system finds an object ahead when automated driving on the high way and issues take-over request to the driver. The subject driver is under the following driver situations : hands-on or hands-off to the steering, and strong or weak distractions.

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.

An experimental study on a reduction of aerodynamic drag and an improvement of fuel economy in platoon driving was conducted to develop an Intelligent Transport System (ITS) with a good fuel economy. Many other useful studies on the platooning have also been carried out. However, no attempt has yet been made to formulate the aerodynamic drag reduction rate in vehicle platooning quantitatively. The formulation is useful for setting goals of vehicle-to-vehicle distance control design and for estimating the improvement of the fuel economy. To obtain the rate without prediction due to the formulation, it is necessary to examine the characteristics of each prototype vehicle in road tests.

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 chocks, 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.

Nowadays 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 bigger fleets. Thanks to mechatronic design of the vehicles and their components, there are many means of optimizing their performance. The paper shows an approach developed to increase the range of e-vehicle operation substantially. It is based on prior information about the route profile, traffic density, road conditions, past behaviour, mathematical models of the route and vehicle and dynamic optimization. The a-priori knowledge is taken into account. The most important part of the procedure is performed in the cloud, using both computational power and rich information resources. Suitable route discretization into sections is most important part of the algorithm. The various information resources are used.

Recently such issues as aging, environments and energy are becoming serious social problems. We're developing a new personal mobility unit to support the short-range transportation in urban areas to solve these problems. Our new mobility unit enables the comfortable and safe movement in an indoor/outdoor pedestrian space including public roads. So far two different types of units according to the user attribute are developed. They are with a safety function to limit the travelling speed automatically corresponding to the surrounding circumstances. Also our verification test results on a public road, which shows an effectiveness of the unit is discussed in this paper. This paper describes the concept of those mobility units, the principle and effects of the safety features.

Abstract The paper presents a simple but effective algorithm for managing the signaling intervals at high density traffic intersections based on traffic intensity on a particular side. We observe that most high density traffic intersections receive heavy traffic from specific directions at specific timings which repeat periodically. So, the idea aims at providing less waiting time for vehicles at signals by manipulating the time intervals for the Red/Green signaling on the basis of vehicle density. The solution is designed to solve the problem of commuting time to some extent in a day to day life in densely populated countries where it becomes difficult to keep an easy check on the vehicle movement through manual efforts. This algorithm is also intended to help emergency vehicles which gets stuck into heavy traffic jams and in turn reduce casualties. This algorithm can also prove effective for pedestrian safety and for several other purpose.
