THE CLO2 was comprised of these 3 major topics:
Module 2: Design of Highway and Railway Engineering Systems
This module is concerned with the geometric and structural design of nhighways and railways. Cross sections, horizontal and vertical alignments, super-elevation and earthworks will be discussed.
Study Guide # 1
a. Introduction to Transportation Planning & Engineering
b. Transportation as a System
c. Urban Transportation Planning Concepts
Study Guide # 2
a. Philippine Transportation System
b. Transportation Safety & Economics
c. Transportation Policy Analysis and Planning/Technical Tour
Study Guide # 3: Introduction to Travel Demand Forecasting (Classic Four- Step Forecasting Model)
Study Guide # 4: Traffic Impact Assessment
One concrete application of this second-course learning objective would be in terms of CROSS-SECTIONS AND ALIGNMENTS OF HIGHWAYS AND RAILWAYS. In particular, the elements of the highway. In this particular work, we were tasked to capture a highway and determine the elements that surround the chosen highway itself. At first, it was quite challenging because some of the terminologies are quite similar, but in the end, I was able to find out which is which and be able to realize that we engineers have so much more to offer in this world.
4. Physical Element
These elements include highway capacity, access control and management, pedestrians, bicycle facilities, safety and environment. Knowledge of highway capacity is essential to properly fit a planned highway to traffic demands. Access control to manage interference with through traffic is achieved through the regulation of public access rights to and from properties abutting the highway facilities, and can compromise full control, partial control access management or driveway/ entrance regulations. Pedestrian facilities including sidewalk, crosswalks, traffic control features, curb cuts, ramps, bus stops, loading areas, stairs, escalators and elevators warrant due attention in both rural and urban areas. Existing streets and highways provide most of the network used by bicycle travel, making bicycle traffic an important element for consideration in highway design. Because the number of crashes increases with the number of decisions that need to be made by the driver, it is in the interest of safety that roadways should be designed to reduce the need for drivers’ decisions and to reduce unexpected situations.
5. Economic Factors
Highway economics is concerned with the cost of a proposed improvement and the benefits resulting from it.
Upon learning the basics, I learned that surveying doesn't only be applied in a short basis but for a longer one since it is applied in such industries like engineering, etc.
Module 2: Design of Highway and Railway Engineering Systems
This module is concerned with the geometric and structural design of highways and railways. Cross-sections, horizontal and vertical alignments, super-elevation, and earthworks will be discussed.
In this module, Highway Design is a process that includes a series of actions/ steps to be taken to generate a clear and precise understanding of the project’s requirements and public needs. Establish highway route; identify horizontal and vertical curves along the highway; locate the culvert structure and drainage flow passing through the location; and design the pavement thickness, as well as sub base and subgrade thickness.
DESIGN CONTROL CRITERIA:
1. Human Factors and Driver Performance
Considerations include:
Driver task that includes vehicle control (such as simultaneous multiple tasks and reaction time), guidance (such as road following, lane placement, car following, passing maneuvers and response to traffic control devices and navigation
Use of the facility by older drivers and older pedestrians
Errors due to driver deficiencies and situational demands
Speed
2. Design Vehicles
Four general classes of design vehicles are (1) passenger cars, (2) buses, (3) trucks (4) recreational vehicles. In the design of any highway facility, the designer should consider the largest design vehicle with special characteristics appropriate to a particular location in determining the design of such critical features as radii at intersection and radii of turning roadways. As a general rule:
3. Design Volumes Traffic Characteristics
The design of a highway and its features should explicitly cover traffic volumes and traffic characteristics. Traffic volumes obtained from field studies (such as hourly and daily traffic volumes, type and weight of vehicles and traffic trends) can indicate the need for improvement and directly influence the selection of geometric design features, such as number of lanes, widths, alignments and grades. Relevant studies include Average Daily Traffic (ADT), peak hour traffic, directional distribution, composition of traffic, projection of future traffic demands, speed and traffic flow relationships characterized by the volume flow rate in vehicles per hour, the average speed in kilometers per hour, and the traffic density in vehicles per kilometer.
It is evident in this topic that I applied the concepts associated with the geometric and structural design of highway and railway engineering systems. That can be proven by the work I have done to make sure that I identified the elements of highway that can be seen in the upper left corner of this page.
