Two-way communication, centralized traffic management, video surveillance, and automatic vehicle location/identification are some of the areas in which research is taking place. To examine the effectiveness of each of these technologies and strategies, they must be tested on the highway. However, to minimize disruption to the system and potential safety hazards, many of these technologies are first being implemented and tested in an off-line environment. The Cal Poly Testbed Laboratory consists of an Instrumented Test Track, a Transportation Management (TMC) Center Simulator, a Communications Development Laboratory, a Test Track and other support laboratories. The Testbed Lab is being used in the development, testing, and demonstration of potential technologies prior to implementation in the field.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

The EDDIT programme has conducted the evaluation of a French version of the CARIN guidance system with a sample of elderly drivers. The subjective view of the system was positive. A majority of the elderly subjects found the system easy to use and comfortable to drive with. Some possible problems related to the answers to complex or equivocal guidance information while driving in the trials have been identified.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

The AVI facilities developed for the heavy vehicle electronic license plate (HELP) project on the I-5 corridor was used for this purpose. The static axle load of AVI-equipped vehicles was obtained from the Oregon DOT for two sites, namely Woodburn South-bound and Ashland Northbound. The WIM load data was obtained from Lockheed IMS for all the WIM systems on the I-5 corridor. The data was analyzed to sort-out AVI numbers, dates and times of weighing. Time limits for traveling between sites were established to ensure that trucks had no time to stop and load/unload cargo between sites. Errors were calculated as the percent difference between WIM and static loads for individual axles/axle groups. Calibration factors were derived to set the mean axle weigh error to zero. Software was written to handle all calculations.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

The proposed network does not require a central server or database, although any agency on the network can create databases for any purpose. All integration of operations is achieved by implementation of joint operating plans developed cooperatively by the involved agencies. Any agency's system can act as the \"master\" when needed in implementing such coordinated plans.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

These were: (1) studying dynamics of bus behavior at a single bus stop; (2) extending the dynamics of bus behavior study to multiple bus stops; and (3) developing a prototype bus arrival time prediction model. The prototype travel time estimation was tested and evaluated through the simulation.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

After several years of significant efforts in the area of transfer standards, a family of compatible standards is evolving which will serve national and international requirements well. The de facto international transfer standard for navigable map data is the Geographic Data File (GDF) developed by the Comite Europeen Normalisation (CEN, a pan-European standardization body). CEN GDF is currently under a period of extensive revisions and refinements in response to international requirements. There are also several national standards for map transfer, which are moving towards compatibility with the international version of GDF. It is anticipated that the International Standards Organization (ISO) version of GDF will form the foundation for a single international family of transfer standards for IVHS map data. The authors are active participants in national and international map database standards efforts, and recently moderated a workshop on developing an IVHS profile for the Spatial Data Transfer Standard (SDTS). The workshop concluded that ISO GDF should be the basic structure for the IVHS profile for SDTS. This paper reports on the results of that workshop and discusses the current progress in ISO TC 204 on further refining GDF as the ISO standard for map database transfer.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.

These applications include such areas as real time vehicle dispatching systems where potential routes between a large number of origins and destinations have to be continually updated for a variety of vehicles throughout the day. The objective of this paper is to demonstrate the feasibility of using an artificial neural network (ANN) to estimate the O-D travel time in a dynamic traffic network. Three feedforward neural networks were developed to model the travel time behavior during different time periods of the day: AM peak, PM peak and off peak. These ANN models were subsequently trained and tested using a network from the City of Edmonton, Alberta. A comparison of the ANN model with a traditional statistical model is then presented. Lastly, the computational efficiency of the proposed ANN model compared to two shortest path algorithms is demonstrated. The statistical results show that the ANN models are appropriate for estimating dynamic O-D travel times and are significantly faster than the exact minimum path algorithms.","PeriodicalId":337008,"journal":{"name":"Pacific Rim TransTech Conference. 1995 Vehicle Navigation and Information Systems Conference Proceedings. 6th International VNIS.
