Passing vehicle

Check traffic patterns of the target area to discover what types of vehicles routinely use the road. If few or no heavy trucks travel die road, then the charge may be safely emplaced directly under the road surface. The charge should still be in a stoutly constructed box to prevent damage from the weight of passing vehicles. [Pg.37]

This kind of photoelectric relay is quite sensitive, and will perform with a light pulse as brief as l/60th of a second in duration. Placement at a crime site must be accomplished with discretion, since the light of a passing vehicle might cause initiation at the wrong time. [Pg.331]

Higher than 1.25 density is required to make the base stable against wind forces and vacuum forces created by passing vehicles. This was achieved by using the slush molding process and formulation given in the above table. [Pg.271]

Where roads or railways cross a pipeline, in addition to soil pressure, they are subject to further static and dynamic loads from passing vehicles. If the soil cover is less than 1.5 m, traffic loads dominate. For cross-country pipes under railway embankments or paved roads, it is possible to calculate soil pressure and traffic loads and hence the loads on the pipeline. The additional loads must be taken into account when determining the dimensions and properties of the pipes, and special measures may ultimately be necessary. [Pg.641]

Driver failed to leave sufficient room for passing vehicle to get safely back in line... [Pg.729]

There are two ways in which one may probe these emissions and whether they comply with legislation. One is during the standard vehicle inspections carried out by the national vehicle inspectorates, normally once a year in the UK. However, this does not guarantee that in between these official checks the car continues to meet the legal requirements. Therefore, in situ real-time roadside checks are desirable, which can rapidly and precisely measure the emissions from a particular vehicle, and in addition identify the offender. For this to work, instrumentation has to be low cost and the measurement technique has to be non-invasive to enable rapid on-road testing of passing vehicles without inconvenience to the motorist. [Pg.404]

To minimize the intake of exhaust fumes from passing vehicles, the blower intake should be positioned away from the flow of traffic. Wind direction also must be considered. Ventilation of the manhole must continue as long as the manhole is open to avoid the possible development of a hazardous atmosphere. [Pg.110]

Designers sometimes specify street furniture at the front of footways but Road Safety Auditors may be concerned that such furniture can be struck by passing vehicles. [Pg.151]

Probability of the scenario developing 70% Examples are the vessel/line will succumb to the over-temp, over pressure etc. the release has an impact on the passing vehicle. [Pg.29]

Danger of fire must not be underestimated. Defects and harms are rarities, but when they occur the costs are high. To avoid fire by high temperature, short circuits (due to defects on the cables, perhaps damaged by passing vehicles), etc., means prophylactic controlling and maintenance and keeping the batteries dry and in proper condition. [Pg.202]

This study uses speed data from six sites, all of which had a camera in place for the after measurements. AU sites were on rural roads with a speed limit of 90 km/h. Speed data were collected using pneumatic tubes stretched across the road. The speed measmements used here were made before (August/September 2010) and after (September/October 2010) the speed cameras were installed. At each site and on each measurement occasion, the speeds of passing vehicles were registered for one week. In total, the speeds of approximately 115,000 vehicles were registered per occasion (before and after). Only speeds of vehicles travelhng in the direction of the camera orientation were considered. [Pg.166]

At a low ambient luminance including fogged up side windows and/or droplets on the side mirror, the CMS showed an image that was hardly affected by the weather, compared to conventional mirrors (Fig. 25). The reflection seen on the monitor is caused by the camera flash. The passing vehicle remains more clearly visible than in a mirror. [Pg.389]

The direct comparison between Figs. 26 and 27 shows the influence of a possibly overexposed camera, due to the badly set head lamp of the passing vehicle, on the display of the scene in the CMS. Therefore, the influence of head lamps causing glare on the image reproduction by the CMS is possibly higher than the influence on the conventional mirrors observed for comparison. [Pg.390]

Although a system such as that shown in Figure 11.1 is inherently safe, the drain valve in the wall has to be checked. It is needed because it will be necessary to drain rainwater from the contained area. But if the valve is left open or if the drain line is broken, say by a passing vehicle or by someone treading on it, then the secondary containment will be nullified. [Pg.228]

When operating a walkie-rider from the operator platform, operators should place one hand on the control handle and the other on the grab bar. It is critical that operators keep the entire body inside the operating area—otherwise they can stick out and strike fixed objects or other passing vehicles posing serious hazards. [Pg.504]
