This paper discusses how simulation models are being used on the Central Artery/Third Harbor Tunnel Project to develop incident response plans and to evaluate the design of the Integrated Project Control System. This simulation effort is comprised of four phases: use of the INTEGRATION Network Simulation Model to develop incident response plans; (2) use of the MIT Dynamic Traffic Model to test and evaluate the proposed control system design; (3) further development of the MIT model to be used as a tool in the operations control center (OCC) for fine-tuning incident response plans; and (4) development of a concept for a future predictive simulation model to be used on-line in the OCC. The first two of these efforts are underway, the third is being evaluated, and the fourth represents a possible future implementation in the OCC.

California Polytechnic State University, USA, completed an assessment of the potential of using a video image processing (VIP) system for traffic surveillance and detection on California freeways. The first phase of the project, sponsored by the California Department of Transportation, was completed in 1991. Eight turnkey and prototype systems were identified and tested under laboratory conditions. The results showed, that while no system tested was ready for deployment at that time, several systems warranted further testing under more realistic conditions. The second phase of the project began in June 1992 and was completed recently. Four VIP systems were chosen for extended field testing to measure accuracy in traffic counts and speeds, classification, reliability, cost, ease of set-up and operation, image quality, failure rate, and ease of recovery. These variables were assessed quantitatively and qualitatively under specific conditions that included variations of lighting, approaching and departing traffic, camera angle, weather, vibration, and presence of signal noise. This paper presents the Phase II field test results and recommendations for standardizing image processing systems with a view toward eventual statewide implementation for traffic detection.

The "simulated field test of an open architecture transportation controller (OATC)" accomplished an initial demonstration in a laboratory environment of the feasibility and capability of an OATC as a vital component of an advanced transportation management system (ATMS). This simulation involved the integration of the OATC with expert system software named "FRED" developed at the Institute of Transportation Studies (ITS) for real-time traffic management and control as part of a future ATMS. A cross platform interface was built for the expert system to communicate with the OATC. Software was implemented on the OATC to test the TCBLKS (traffic control blocks) software model and structure. The results of this field test demonstrated that using the TCBLKS was simple and intuitive. This field test also revealed many of the benefits of integrating the OATC and FRED such as data sharing and the potential for distributed processing.

Significant efforts are being made at present to define, evaluate, and ultimately deploy, various forms of intelligent transportation systems (ITS). These systems permit the implementation of advanced traffic control strategies through the application of advanced surveillance, control and communication systems. Traditionally, the evaluation of the performance of these communication systems and traffic networks has been performed predominantly independent of each other. This paper describes the development and application of an extension to an ITS benefits evaluation model to permit a partially coupled evaluation of the communication system loading and the ATMS/ATIS functions. This extended model is capable of estimating dynamic local and network wide communication loadings that depend on the spatial and temporal traffic demands, the network topology, the characteristics of the communication hardware and the communication system operating rules. The model is applied in this paper to a simple hypothetical network to demonstrate the potential benefits of carrying out a partially coupled evaluation of communication system loading and traffic network efficiency. A sensitivity analysis was carried out to determine the impact of the fraction of ITS equipped vehicles and the level of congestion on the level of communication loadings. It was demonstrated that, as a result of congestion and traffic diversion, antenna communication loads did not uniformly increase in direct proportion to the average number of equipped vehicles entering the network.

Experiments were conducted in a moderate-fidelity desktop simulator to investigate the attentional demand of four types of turn-by-turn route guidance displays. Subjects had to perform a tracking task with the mouse and record their decision to turn left, go straight, or turn right at an intersection, by pressing the left, middle or right mouse buttons. The RMS value of the tracking error and the response time to the pressing of the buttons, were the performance measures. Two of the turn-by-turn displays (one of which was text based, and the other that did not contain street names but merely a count of intersections to the turn) performed worse than the other two turn-by-turn displays. The most effective and preferred display was the one which used countdown bars to supplement text elements concerning distance from the turn location, retained turn location intersection geometry as part of the display, and provided symbolic cues when a turn was imminent.

The need for performing freight displacements fitting both the just in time manufacturing technique and low environmental impacts led transportation researchers' interest to integrated transport chains. Intermodal networks are composed of nodes and links, and their competitiveness, with respect to the road transport, depends on the performances of each network component, and on the whole network organization. This work deals with integrated transportation terminals (i.e., the network nodes), and it presents an interport model, the guidelines of a model-based simulation tool, and a cost function which was purposely drawn to evaluate the terminal performances.

Existing studies for road network O-D estimation from link counts remain exploratory in nature, mostly developed on the assumption of having reliable prior O-D matrices and an accurate dynamic traffic assignment model. The computational requirements for use in large-scale networks have never been addressed either. This research presents a mathematical model and its computing architecture that allow for real-time estimation of dynamic O-D matrices in large-scale networks. The proposed model employs only link flow counts and dynamic screenline flows, and makes no assumption on drivers' route choice behavior. For a large network, the proposed model attacks the complex estimation issue in two stages: decomposing the entire network into several subnetworks for parallel computing in the first stage, followed by the update of key parameters with specially-designed screenline flows in the second stage. The preliminary results have shown the promising properties of the proposed method.

The authors discuss two available methodologies used for ergonomic evaluation of in-vehicle systems. One method corresponds to the objective measurement of the driver's behavior, and more precisely the visual strategies, and the other one belongs to the subjective evaluation category and is used for rating the mental workload of a task. For this second approach, the authors propose a new version of the TLX adapted to the driving task and called the DALI-Driving Activity Load Index. Both objective and subjective approaches are illustrated with results extracted from the ergonomic evaluation of the guidance/navigation system CARMINAT tested in the Lyon urban area.

One of the most important aspects of traffic management systems is their ability to detect traffic incidents such as accidents, disabled vehicles, and obstacles on the road. The incidents affect highway drivers and cause traffic congestion, so an immediate and automatic detection method is desired. We think that the changes in traffic average in case of traffic incidents have certain patterns different from the normal case. Our research tries to detect traffic incidents immediately and automatically by using neural networks, which use one minute average traffic data as input, and decide whether an incident has occurred or not. To train the network we used traffic data from various locations where accidents had occurred and not. The former are generated by a micro simulator and the latter are collected by using ultrasonic vehicle detectors. To reduce the number of false detections so as to improve the process of training of the neural network, we added some data with similar average change patterns as observed when incidents occurred. As a result, we confirmed that adding enough combinations of similar average change patterns was very effective in increasing the recognition rate and to reduce the number of false detections.

The paper discusses a feasibility study of a bus passenger information system operational test in a rural area-Blacksburg, Virginia. Four objectives have been identified to fulfil the feasibility study of the passenger information systems in Blacksburg: (1) survey the rider's characteristics and information needs; (2) study information system hardware alternatives and human factors to meet the needs; (3) design a user-friendly computer model; and (4) design a passenger information system. The survey revealed that 84 percent of the Blacksburg Transit riders do not refer to the information brochure for various reasons, and 75 percent of the riders prefer information signs at the bus stop, and the automated information system as modes of information aids. Due to cost effectiveness, the touch screen with cable TV was found to be suitable for the system in the hardware alternatives study. Major bus stops at Burruss Hall (center of the university), the library, and student center are highly recommended for system installation for on campus riders. According to the survey results, an interactive computer model for the passenger interface was designed. The total cost for a system is estimated at $7000/unit. From the high survey return rate as well as survey results, it is apparent that riders in Blacksburg want the improved and advanced information system for their community. Therefore, if this system is implemented for operational test, it will improve the operational concept of current passenger information systems and increase the level of service.
