The target is to meet vehicle safety applications' requirements of high reliability and low delay in reception. The communication is one-to-many, local, and geo-significant. The vehicular communication network is ad-hoc and highly dynamic, with potentially large number of contending nodes. We design several random access protocols residing in MAC and MAC extension layers. The protocols fit the DSRC multichannel architecture. Analytical bounds of the protocols' performance are derived. Simulations are conducted to compare the performance of the protocols in terms of reception reliability and channel usage efficiency. The sensitivity of the protocol performance is tested under various communication conditions as well as vehicle traffic conditions. The results show that our approach is a feasible solution to the MAC design problem to support vehicle safety communications.","PeriodicalId":239269,"journal":{"name":"Proceedings.

In a crossing, the usual black road surface is painted with constant width periodic white lines. In Japan, this width is 45 cm. The crossing region as well as its length is detected using this concept. At first, the crossing direction is determined from the power spectrum using fast Fourier transform. The periodic white and black bands are detected using integration along the crossing direction and differentiation of the integral data perpendicular to the crossing direction. Then the crossing length is calculated using the number of white and black bands in the crossing region. Experiment is performed using real road scenes with pedestrian crossing. The technique is successful in measuring the length of the crossing with high accuracy if the image resolution is good and the white paintings on the crossing are fine.","PeriodicalId":239269,"journal":{"name":"Proceedings.

The method is based on two kinds of epipolar-plane image analysis; one is edge-based algorithm and the other is region-based algorithm. Both algorithms are fused to achieve higher reliability.

This technique can be used to improve the robustness and accuracy characteristics of the low-cost standalone GPS receivers. A new nonlinear model including the errors computed using navigation messages (acquired from the satellite transmitted data) for position estimation is developed. A new GPS positioning method based on an iterative algorithm, and the new model are proposed. The method uses an algorithm that iteratively uses unscented Kalman filters and smoothers to compute the position estimates. The first experimental results, and comparison of the results obtained with different algorithms are also presented. First results show that our approaches provide better estimation than other solutions. Future research directions are also discussed.","PeriodicalId":239269,"journal":{"name":"Proceedings.

Engineers, planners and freeway management system operators in many urban areas are finding themselves working in an increasingly data rich environment. The availability of these data allows analysis of multiple aspects of a freeway network from a regional scale down to a single incident. This study uses archived ITS data to evaluate the effectiveness of a freeway incident response program in Portland, Oregon. Data used in this study were extracted from an archived computer aided dispatch database, automatic vehicle location systems, inductive loop detectors, automatic traffic recorders and weather archives. The data are used to show various ways of presenting transportation information being used as indicators of the effectiveness of an incident response program. This type of evaluation is necessary on an on-going basis in order to clearly articulate the benefits and costs of this critical component of the region's traffic management system.","PeriodicalId":239269,"journal":{"name":"Proceedings.

This paper focuses on circular road signs and achieves almost perfect performances under various conditions such as daytime, evening-time and nighttime. Moreover, the proposed method may be applicable to recognize of any shape of road signs. The effectiveness of the proposed method has been demonstrated through experiments.

We address this problematic using a platoon of cars considered as a multiagent system. To do that, we propose a hierarchical architecture based on three layers (guidance, management, traffic control), which can be used to develop centralized platoons (where a head vehicle-agent coordinates other vehicle-agents by applying coordination rules) and decentralized platoons (where the platoon is considered as a team of vehicle-agents maintaining the platoon together). We propose the model of teamwork used in multiagent systems as a decentralized alternative to previous coordination centralized on the platoon's leader and outline its benefits using collaborative driving simulation scenarios.","PeriodicalId":239269,"journal":{"name":"Proceedings.
