What does OHVD mean in TRANSPORTATION
OHVD is an abbreviation for Over Height Vehicle Detector, a system used by government agencies to detect large vehicles that exceed the height limits set by road authorities. This system is important for preventing accidents caused by oversized vehicles on roads and highways. OHVDs are often found at highway entrances or near bridges and overpasses. The system consists of sensors which detect any vehicles that are too tall for the permitted limit, sending out an alert signal when an overheight vehicle is detected.
OHVD meaning in Transportation in Governmental
OHVD mostly used in an acronym Transportation in Category Governmental that means Over Height Vehicle Detector
Shorthand: OHVD,
Full Form: Over Height Vehicle Detector
For more information of "Over Height Vehicle Detector", see the section below.
How does OHVD work?
The OHVD system works by installing laser beams over highway entrances and bridges where it can detect the height of passing vehicles. If a vehicle exceeds the allowed height threshold, the system will trigger an alarm to alert nearby personnel about the presence of an oversized vehicle. These alarms can be visible and audible or simply visual, depending on the type of installation used. Additionally, some systems are equipped with automated barriers that will lower or raise to stop over-height vehicles from entering or leaving highways or bridges.
Benefits of using OHVD
The use of OHVDs helps prevent serious accidents as well as property damage caused by oversized vehicles attempting to pass through low clearance areas such as tunnels and bridges. This also helps reduce traffic congestion on highways as drivers must abide by the legal height limits when they enter a bridge or tunneled roadways. In addition, this system can be easily set up and monitored remotely, allowing road authorities to better manage their road networks.
Essential Questions and Answers on Over Height Vehicle Detector in "GOVERNMENTAL»TRANSPORTATION"
What is an Over Height Vehicle Detector?
An Over Height Vehicle Detector (OHVD) is a system that detects the height of an arriving vehicle. It is usually installed near bridges, tunnels, or other structures where it's important to control the size and weight of vehicles entering. The OHVD uses sensors to measure the height of a vehicle and can detect any over-height violations, allowing authorities to take appropriate measures if needed.
How does an Over Height Vehicle Detector Work?
The OHVD uses electromagnetic sensors to detect when a vehicle passes by that is higher than the pre-determined height limit. The sensors send this information to a control panel which records the details and alerts personnel of this violation.
What are the benefits of using an Over Height Vehicle Detector?
An OHVD provides more reliable detection than traditional manual measurement techniques, reducing potential for human error. It can identify over-height vehicles quickly and accurately, helping prevent them from entering restricted areas or damaging infrastructure. This in turn helps protect safety and security by ensuring only vehicles that meet certain specifications are allowed through.
What type of applications benefit from an Over Height Vehicle Detector?
OHVDs are especially useful in areas where controlling the size and weight of vehicles passing through is essential - such as near bridges, tunnels, railways or airports - as well as where security needs to be monitored closely.
How frequently should an Over Height Vehicle Detector be checked?
For optimal accuracy, it’s recommended that you check your OHVD regularly - at least once every few months - to ensure all components remain working properly. In addition, checking for signs of wear such as frayed cables or rust on metal parts will help keep your unit running smoothly.
Does an Over Height Vehicle Detector require maintenance?
Yes – as with any electronic system regular maintenance should be carried out on your OHVD in order to keep it functioning correctly and improve its longevity. This should include making sure all connections are secure, replacing worn parts when necessary and cleaning off any dirt or debris buildup on sensors or other components.
Are there different types of Over Height Vehicle Detectors?
Yes – there are several different types available including radar based systems, laser systems, infrared beam detectors and manual pole detectors. Each one has its own advantages and should be selected based on your specific requirements.
What kind of accuracy can I expect from an Over Height Vehicle Detector?
Depending on the type selected most OHVDs offer accuracies ranging from 0-3 cm for standard models up to 0-1 cm for higher end systems. Accuracy also depends on factors such as environmental conditions so make sure you consider these before making a purchase.
Is it difficult to install an Over Height Vehicle Detector?
No – most models come with easy installation instructions which involve mounting onto solid ground with either bolts or concrete anchors depending on surface type; wiring up power supplies; connecting control cables; setting up angles; calibrating sensitivity settings etc.. Most people should be able to complete their own setup without needing professional assistance.
Final Words:
In conclusion, Over Height Vehicle Detector (OHVD) systems provide a safe and convenient way for government agencies to monitor their roads and highways for oversized vehicles. By monitoring these areas with specialized sensors and alarms, governments can help prevent accidents while also reducing traffic congestion in restricted areas like bridges and tunnels. With its many benefits, this system could prove essential in preserving public safety while providing better management of roads across various nations worldwide.
