In tunnel environment, positioning is challenging, since neither GPS sensors nor ordinary cameras function properly. In this paper, we propose a real-time solution for positioning of vehicles. In tunnels, we can gain the absolute coordinates of some specific objects, here the emergency telephone indicators, which are some special lights. Then during the travelling in tunnels, we sense the environment using infrared cameras and detect the emergency telephone indicators to infer the experimental vehicle's position. In our detection method, we make use of both the emergency telephone indicators' appearance information and motion information. Through well balancing the pipeline, by making time-consuming steps deal with fewer instances, we gain a real-time detection method with promising detection results.

However, the Great East Japan Earthquake that occurred in March 2011 and brought about immense damage mainly to the northeast of Japan, caused full suspension of the train system and entry restriction of highways, resulting in long-term congestion with people and vehicles jamming the streets.
In a large-scale disaster situation, where securing emergency traffic routes for search and rescue and avoidance of massive congestion is essential, the role of the TCS is huge.
Since an earthquake is expected to occur directly beneath the Tokyo in the near future and building on these lessons, the MPD is promoting various efforts to realize the full potential of the TCS even under a large-scale disaster situation.

The simulator allows transit service operators and transit information services to evaluate how service scenarios can affect various types of users with different user profiles. The simulator allows specifying multiple different user profiles which affect the changes of user states over time during trips and dynamic mid-trip switching of multi-modal routes. An example is presented of an urban mass transit scenario using real transit system data in Sydney Australia.

Conventional traffic-flow simulators that examine the effectiveness of a park-and-ride system are insufficient, because it is not practically possible to consider all timetables of the public transportation. In this study, using a mathematical optimization technique, we develop a method to obtain an optimal train timetable for a road network employing a park-and-ride system. The proposed method enables us to assess the effectiveness of a park-and-ride system more accurately to reduce congestion on a road network.

Vehicle-to-Pedestrian (V2P) communication which can coexist with V2I and V2V communication on the same frequency is required for pedestrian’s safety. This paper proposes three access methods which are suitable for the system. The possibility of coexistence was confirmed by static simulation in which several roadside units (RSUs), a lot of on-board equipment (OBE) and pedestrian portable terminals (PPTs) are distributed throughout a large intersection.

The advantage of probe data is that it enables traffic administrators to observe traffic flow conditions of ordinary roads, including local streets with no vehicle detectors installed. Furthermore it is possible to acquire the flows of turning traffic at signalized intersections which has not been possible to obtain by detectors. In this study, we collected probe data of taxis traveling around Yokohama City, and estimated the travel time and ratios of turning traffic flows based on only probe data. It is found that the probe data can be significantly utilized for traffic management purposes such as signal control and information provision in spite of their sparseness. Moreover, the results suggest that if the data are accumulated for sufficiently long periods of time, the traffic flow conditions can be accurately estimated.

But the ultrasonic detector would increase maintenance cost since two sets of a transmitter and a receiver need to be mounted away. Applying radar to the detector, it can be one set, but radar which has to transmit wave to vehicle orthogonally cannot ordinarily calculate speed of vehicle from observed Doppler shit in the reflected wave. In this paper, we propose phase rotations template matching method, which evaluates a correlation between observed phase rotations and theoretical templates, to calculate speed of vehicle with radar transmitting orthogonally. We experimented to use prototype 60GHz radar and 63 vehicles running slow. Calculated speed is accurate to within 2.0[km/h].

Our proposal should contribute to reduction in production costs of accurate digital maps. The digital road map includes road marking, road network, and road boundary. The most striking feature of our proposal is vehicle trajectory estimation using GPS Doppler. This enables to integrate probe data that is collected by many vehicles, because of each vehicle's heading error is vanishingly small. In this paper, we mainly describe orth-image generation and road marking detection.

The detection performance is 40-meters maximum range and 110-degrees azimuth within 100-milliseconds processing cycle. This sensor is realized by key technologies of 'Tx/Rx adaptive array antenna' and 'the advanced coded sequences pulse modulation'.

This paper proposed a sensor fusion method which combines the radar power profile with the disparity histogram from stereo camera. Using the combined new feature, the fusion senor can achieve a highly accurate positioning performance. The evaluation experiments show that the proposed method achieved high resolution on both range and angle. Using the highly accurate position information, pedestrians at the distance of 40m are successfully separated from nearby cars.

In order to improve actual fuel consumption, eco-driving support systems for the use of environmental information and circumstance prediction are necessary. Therefore, circumstance prediction methods have to be developed. In this paper, we propose a method to predict the preceding vehicle's behavior (going straight/turning left) at the intersection. It utilizes a feature that the difference of the preceding vehicle's profiles of velocity and acceleration becomes wider when the vehicle approaches closer to an intersection depending on the driving behaviors. First, the method collects the patterns of the vehicle behavior when the own vehicle goes straight or turns left. Then, by comparing the patterns with the preceding vehicle's behavior, it predicts whether the preceding vehicle is going to decelerate. The effectiveness of the proposed method was examined by a preliminary study.

This active form of traffic management requires traffic data with a certain quality level, although this is not taken into account in current plans. An organization plan to guarantee data quality for regional traffic management, based on various literature and expert interviews, was created and validated with experts. The plan contains a chain manager responsible for managing data quality through the information chains of regional traffic management and four different data management steps: define, measure, analyse and improve. The validation revealed that this plan brings substantial improvement on current practice.

The framework consists of a recursive decomposition of a large network and a recursive control strategy. The framework distributes the complexity of NM among different levels and, per level, among a number of subnetworks, such that each management instance has only a limited amount of complexity to cope with. In this way, NM becomes feasible and scalable, such that it can be applied to heterogeneous networks of arbitrary size.

In this paper, we present the results of a user study carried out within Renault, using a dynamic simulator. Nine use cases were presented to 36 naïve drivers in order to measure their attractiveness to users and their impact on driving activity. Driver behaviors were recorded and followed by in-depth interviews. The road safety use cases were met very positively, provided that the information complemented normal perception. In contrast, the manner in which drivers considered the use cases related to road signs was much more variable. Some users viewed them as very useful, since they thought that driving safety begins with traffic-related information. Other users barely tolerated them, and even found them to be annoying when they were already able to access this information via other devices.

With market parties being able to offer more and better data at lower cost, and with in-car systems used for communication to the driver, there is a big opportunity for making TM more efficient and effective. The emerging vehicle automation and communication technologies will change the current system towards an in-car based system, leading to a so-called in-car centric TM approach.
In this paper, we shortly elaborate on the minimum set of components needed for effective in-car centric TM. Subsequently, we show that massive introduction is very beneficial for improving the societal goals of efficiency, safety and environment. We describe the societal benefits during the transition phase and the potentially avoided TM costs, saving governmental budgets. Conclusion is that in-car centric TM is already feasible on short term and has a ROI of 3 to 4 years.

For this purpose, representative test routes were defined, including sections with significantly different driving conditions and the ECO mode. Furthermore, driving tests at different constant speeds on freeway were performed.
The test vehicle was equipped with a state of the art portable emission measurement system for real-time operation. The method is based on a modal analysis of the emission concentrations in the tailpipe of the vehicle. The exhaust gas mass flow is calculated from the air mass flow and the gas components. The fuel consumption is determined with the carbon balance method. GPS tracking was implemented to link the received geographical information of the test routes with the measured exhaust emission data. Real-time C2I communication is possible.

There are two main directions for such a fusion: the first direction is that of validating the TMC messages with information obtained from FCD, and enrichment of the TMC messages by such information. The second direction is that of a cooperative and independent fusion: the two-dimensional and time-dependent traffic situation as obtained from FCD can be completed by the more punctual information of the TMC messages. For this purpose, information from TMC (such as road blockings, construction sites) can be used directly within routing services which calculate their routes using FCD information. The information gathered from TMC can also be used to facilitate the calculation of historical traffic heat maps, which visually mark regions where congestions have been experienced repeatedly in the past.

C-ITS are complementing the advanced driver assistance system (ADAS) by providing highly dynamic data reflecting neighboring vehicle movements. However the current positioning and communication technologies are presenting some variation in their performances leading to a careful use the resulting exchanged data elements for critical collision avoidance applications. This contribution presents the fault tolerance approach followed in the French field operational test (FOT) SCORE@F (Système Coopératif Routier Expérimentation @ France) for collision risk management applications.
