Highway-Level of Service
Level of service describes the quality of service provided by highway. The system assesses highways based on speed, travel time, manuever, interrup…
Minor Losses
Major losses occur in pipe network due to the friction between fluid and pipe wall. On the other hand, minor losses occur when the velocity of fluid …
Highway-Speed
For a human and goods conveyance network, speed directly influences its efficiency. The speed of vehicle on road may be affected by the capability …
Highway-Traffic Composition
Vehicles with different size and weights pose different impact on the traffic. Trucks are heavier and occupy more space, thus each of them is equiv…
Highway-Directional Distribution
Design hourly volume usually indicate traffic travels the road regardless their direction. When deciding the number of lanes to be provided for eac…
Beam Deflection - Conjugate Beam Method
Conjugate beam theory stated that the M/EI function obtained from inspecting the internal forces developed in beam, is converted to the function of d…
Highway-Traffic Volume
One of the most notable traffic characteristics is volume. Average daily traffic is commonly used to describe this characteristic. The measured d…
Highway-Driving Task
Driving task can be classified into three categories: control, guidance and navigation. There are many factors that affect the complexity of drivin…
Highway-Elder Drivers
The adequacy of highway design is governed by the users who travel on it. If the design warrants above average skills from drivers, the road may be…
Beam Deflection - Moment Area Theorem
Other than double integration method, we can also use moment area theorem to determine the deflection and slope of beam. The main assumptions for thi…
Highway-Turning Radius
What is the minimum road curve radius that ensure a vehicle maneuvers safely, while optimizing the construction budget? The answer lies within the …
Beam Deflection - Double Integration Method
Euler-Bernoulli’s equation is commonly used to describe the deflected shape of beam. The beam is assumed isotropic, elastic and having consistent cro…
Highway-Design Vehicles
Highway is expected to convey various types of vehicles. The selection of design vehicle often based on the most likely situation. Therefore, whe…
