Traffic application tests

Iimovative ITS applications are tested at three test sites, in Helmond (The Netherlands) with an emphasis on cychsts, and in Valladolid and Alcala de Henares (Spain), with an emphasis on pedestrians. The major aim of the trials is to benchmark the reconunended practices regarding nsability and integration of VRUs in cooperative traffic systems. Based on the evalnation resnlts, an ex-post impact assessment is made of the applications tested in the trials. 

Technically, testing of hair for drugs is no more difficult or challenging than testing in many other "alternative" matrices (for example, liver, bone, etc.). In fact, the application of analytical methods and instrumental approaches are in most cases quite similar, regardless of the initial matrix. At present, hair analysis is routinely used as a tool for detection of drug use in forensic science, traffic medicine, occupational medicine, and clinical toxicology. 

Because of very complex terrain the application of simple dispersion models is very limited in Slovenia. Traffic pollution and the high level of surface ozone are the main current air pollution problems in the country. No official standard model for regulatory purposes has been accepted in Slovenia up to present. The US EPA model ISC3 is used for routine dispersion calculations from point sources. Some other imported models were tested in Slovenia but only on research basis. A neural network forecasting model was developed for the Sostanj thermal power plant. No urban air pollution studies are reported from Slovenia. Air pollution modelling is performed at the Jozef Stefan Institute, Dept, of Environmental Sciences, Ljubljana, Slovenia (US, 2005), AMES d.o.o. and the Hydrometeorological service. 

Field test C was an example of application to surface waters used for human consumption. Such waters were essentially uncontaminated by chemicals and needed only a conventional disinfection. Nevertheless, this plant was monitored in consideration of the fact that accidental pollution by gasoline and oil had been recorded in the past due to the proximity of an adjacent highway with heavy traffic. Figure 16.8c shows a typical mass spectrum of this instance, with no significant ions. This instrument was monitored over 547 days (12,240 analyses, 1020 hours) during which the days off were 37, that is 7% of the period (Table 16.2). 

The repeated triaxial test applies a repeated axial cyclic stress of fixed magnitude, load duration and cycle duration to a cylindrical specimen. While the specimen is subjected to the dynamic cyclic stress, it is also subjected to a static confining stress provided by a pressure chamber. The cyclic load application, though, is to better simulate the actual traffic loading. 

X Assessing applicants — Seventy percent of all companies (90 percent of large carriers) use safety-related criteria to evaluate driver applicants. Ninety percent or more of carriers use drug testing, past traffic records, on-road tests for evaluating driver behavior, and license qualification checks as effective means of assessing the safety risk of driver applicants. 

On-the-road test involves testing the applicant s driving skills in real traffic conditions. Generally, an on-the-road test is relatively short in duration (20-25 miles), and should include various t es of driving conditions including highway, urban, rural, and, if possible, construction zone. 

AE measurement has been applied to the superstructures to evaluate the deterioration or the damage. In this case, in situ measurement under service or traffic loads is desirable. In these applications, the care for environmental noises is essential. This is because the measuring conditions at the site are varied one by one. It is quite important to conduct preliminary tests prior to actual tests on equipment setting and measuring conditions. Based on these well-cared preparations, valuable AE data are to be successfully obtained. 

Test Methods. Field applications on a small scale and under especially stringent conditions accelerate possible failure. Traffic paints are tested by painting stripes across the lanes of traffic instead of parallel to traffic flow. Automobiles are driven on torture tracks with stretches of gravel, through water, under different climatic conditions. Sample packs of canned goods are made the linings are examined for failure and the contents evaluated for flavor after storage. 

By means of an analysis against several DRM-related criteria, the DRM project has selected TOPAZ from a list of candidate DRM methods as a suitable solution for the safety risk assessment of ATM operational scenarios. TOPAZ is an agent-based DRM method that uses Monte Carlo simulations and uncertainty evaluations to analyse the safety risk of air traffic operations up to the level of collisions. The project produced guidelines for the application of this method in SESAR context, and applied the method to a SESAR Test Case of Land vs Line-up Conflicting ATC Clearances. 

ABSTRACT Statistics on traffic accidents annually contain a number of serious accidents involving the hazardous substances on roads and railways, which are accompanied by explosions, fires, leaks of hazardous substances into the environment, or a combination of the two to three mentioned phenomena which have impacts on the protected assets in a traffic accident site, and perhaps as a consequence of internal links and couplings they seriously damage the environment surrounding the accident site. By application of empirical data and procedures of risk engineering it was compiled the check list by which it is possible to determine the critical sites on roads and railways in advance, and it was tested specifically aimed What, If the method, by which it is possible to determine in advance scenarios of impacts of traffic accidents involving the hazardous substances and to determine critical aspects of critical sites from the viewpoint of protection of humans and other public assets. 

Step 4. Define reinforcement benefits in terms of Traffic Benefit Ratio (TBR) or Base Course Reduction Factor (BCR) Requires review of successful applications, field studies, and lab test results.
