Summary
Highway and traffic engineers
Area of Science:
- Transportation Engineering
- Road Safety Analysis
Background:
- Highway and traffic engineering decisions critically impact road user safety.
- Current practices often rely on 'engineering judgment' for critical decisions.
Purpose of the Study:
- To evaluate the extent to which engineering judgment in highway design is informed by safety evidence.
- To assess the balance between safety considerations and utility in engineering decisions.
Main Methods:
- Analysis of guiding documents in highway and traffic engineering practice.
- Assessment of the integration of evidence-based safety anticipation into engineering judgment.
Main Results:
- Engineering judgment in highway and traffic engineering is frequently not informed by evidence-based safety anticipation.
- The balance between safety and other utility dimensions is often suboptimal.
Conclusions:
- There is a significant gap between desired evidence-based practice and current highway engineering decision-making.
- The findings necessitate a re-evaluation of training and practices to improve road safety outcomes.

Design Example: Alignment of a Road Line Using GIS
339
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Survey Safety
380
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Household Wiring And Electrical Safety
1.6K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Heat Engines
3.6K
A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

Internal Combustion Engine
2.6K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...
