Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

699
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Levels of Use of a GIS01:29

Levels of Use of a GIS

110
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

125
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Types of Global Positioning System Surveys

130
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Design Example: Alignment of a Road Line Using GIS

120
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 Safety01:28

Survey Safety

188
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...

Area of Science:

  • Transportation Engineering
  • Traffic Flow Analysis
  • Urban Planning

Background:

  • Assessing the level of service (LOS) for non-motorized vehicles at signalized intersections is crucial for urban mobility.
  • Existing models often do not fully capture the complexities of mixed traffic, particularly in rapidly developing metropolises.

Purpose of the Study:

  • To analyze factors influencing the LOS of non-motorized vehicles at signalized intersections.
  • To develop an improved method for evaluating LOS in mixed traffic environments.

Main Methods:

  • Modified the Highway Capacity Manual (HCM) delay model to include pedestrian traffic rule compliance and fuzzy arrival rate perception.
  • Employed linear regression and cumulative logistic regression to identify key influencing variables.
  • Defined a LOS evaluation index system based on threshold schemes.

Main Results:

  • The modified delay model demonstrated higher consistency with actual traffic data compared to the standard HCM model.
  • Identified critical variables affecting the level of service for non-motorized traffic.
  • Established a new LOS evaluation framework.

Conclusions:

  • The developed LOS model provides a more accurate assessment for mixed non-motorized traffic (electric vehicles and bicycles).
  • Offers valuable references for traffic engineers aiming to enhance urban intersection performance and non-motorized vehicle LOS.
