Evaluation Review
|October 17, 2023
Summary
Spanish provinces show varying road safety efficiency from 2014-2018. Some northern, northeastern, and southern regions experienced efficiency decline alongside technological advancement.
Area of Science:
- Road Safety Analysis
- Transportation Economics
- Spatial Efficiency Evaluation
Background:
- Traffic accidents significantly impede economic development in Spain.
- Disparities in traffic accident fatality and injury risks exist across Spanish provinces.
- Evaluating provincial road safety performance is crucial for targeted interventions.
Purpose of the Study:
- To assess the road safety efficiency of Spanish provinces between 2014 and 2018.
- To differentiate between pure efficiency changes and technological changes impacting annual efficiency.
- To identify geographical patterns in road safety efficiency drivers.
Main Methods:
- Nonparametric Data Envelopment Analysis (DEA) was employed.
- The Malmquist Index was utilized to measure changes in efficiency.
- Safety Performance Indicators (SPI) were defined as inputs for the analysis.
Main Results:
- Road safety efficiency levels fluctuated annually across Spanish provinces during the study period.
- Geographical variations in the sources of efficiency changes were identified.
- A subset of provinces in the north, northeast, and south exhibited efficiency contraction coupled with technological progress.
Conclusions:
- Provincial road safety efficiency is dynamic and influenced by distinct factors.
- Technological progress does not uniformly translate to improved road safety efficiency across all regions.
- Targeted strategies considering geographical specificities are needed to enhance road safety performance in Spain.

01:29Sight Distance in a Vertical Curve
54
Sight distance on vertical curves is critical in roadway design. It ensures drivers can see far enough ahead to identify and respond to hazards effectively. This directly impacts safety, driver comfort, and the overall efficiency of the transportation network.Vertical curves are classified into crest and sag curves based on their geometry. For crest curves, sight distance is determined by the line of sight between a driver's eye and a small object on the road's surface. Design parameters for...

01:17Design Example: Alignment of a Road Line Using GIS
51
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...

01:20Elevation of Intermediate Points on Vertical Curves
32
Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...

01:24Introduction to Vertical Curves
41
Vertical curves are parabolic transitions that connect different grades on highways and railroads, ensuring a smooth alignment between back and forward tangents. The back tangent represents the initial grade, while the forward tangent defines the subsequent grade. These curves can be symmetrical, with equal tangent lengths, or nonsymmetrical, with varying lengths. The key points defining a vertical curve include the Point of Vertical Intersection (P.V.I.), where the tangents meet; the Point of...

01:17Rolling Resistance: Problem Solving
352
Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

01:28Survey Safety
31
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...
