Although each method has its advantages and disadvantages, one would mistakenly think that using a retroreflectometer to collect actual retroreflectance readings is expensive and timely in an economically tight resource. From this point of view, the truth can no longer be out of reach. The use of hand-held sign retro reflectors is undoubtedly the most effective way to determine the on-site performance and replacement needs of signage. The retroreflectometer provides scientific readings that show the nighttime performance of the sign with a single scientific reading without subjectivity, as well as safe daytime physical inspection of the benchmark, hardware and general signage conditions.
Organizations currently using retroreflectometers to determine the performance of the logo often find that their logo is significantly better than the manufacturer's expectations, typically as long as 10 to 20 years. The use of a retroreflectometer to determine the performance of the logo actually saves annually by simply extending the useful range of a significant portion of the existing logo in the field, in terms of replacing the blanket, the proposed logo life and the control mark method. 30-40% of the cost.
Replace each sign in a specific area on a fixed schedule (usually every 10 years) and make a planned replacement at the end of the manufacturer's recommended mark life (usually 10 years). The replacement determined by the control mark in the sign field is determined by the periodic reading of the retroreflectometer. A night check by a trained sign inspector that achieves a specific qualification in a particular vehicle setting by a dedicated driver, supplemented by the use of a control panel.
Periodic evaluation of individual marks using a retroreflectometer and replacement when the mark is near or below the specified minimum level
Either way, the backbone of a successful plan is to establish appropriate processes and data management methods to ensure that there are no signs of unattended over any extended period of time, which can result in costly tort liability.
Based on the cost of the national average signage replacement mark ($150 per mark), the initial cost of the retroreflectometer is usually paid by saving less than 65 marks that could otherwise be replaced by another method.
Another consideration for blanket replacement, the proposed mark life and control mark method is the increased likelihood of tort liability due to the need for separate performance degradation monitoring for early replacement marks. Visual night inspection is another popular method because it is believed that the startup cost is relatively low and the various markers need to be checked to reduce the reflective performance. However, nighttime nighttime visual inspections have hidden costs ranging from approved vehicle specifications to generally higher resource salaries and training costs, to higher security risks for employees who have to travel at night, which may result in Subject to the high degree of subjectivity of infringement review. Using a retroreflectometer to obtain the actual retroreflectance reading for each marker is the only way to truly inventory all the markers, use hard data to actively monitor and perform physical checks during the day's security and perform other duties on site.
In order to monitor the geographical location of the measurements, the GPS is integrated in the spectrophotometer. The important feature is that the update time should not exceed a few seconds. There is also precision. Fast and accurate retesting using GPS, using a 50 channel GPS precision receiver in the retroreflectometer. For monitoring environment weather dur ing measurement time, monitored. Air temperature and air humidity RL and data can be stored in the gonio meter by GPS, temperature and humidity measurements. Storage capacity exceeds 200000 measurements. All instrument settings including calibration are also stored
The growing portfolio of retroreflectometers now includes a custom measurement service designed to measure the retroreflectivity of all types of road markings using state-of-the-art dynamic retroreflectometers. The retro reflector has been tested and certified to dynamically measure the retroreflective brightness factor (nocturnal visibility RL) of road markings, regardless of travel speed, and is measured the same as a static, portable retroreflectometer.
Dynamic retroreflectometers measure road markings at normal traffic speeds, providing an ideal method for covering a wide range of road networks, including highways and main roads, while ensuring the best for operators and other road users. Security practice. Since the ambient light monitoring function is built into the system, the measurement of the retroreflective brightness RL can be performed during the day or night. The retro reflector consists of a measuring head mounted on both sides of the vehicle, a junction box and a laptop with a separate display touch screen that shows the location of the mark.
The dynamic retroreflective surveyor aligns the vehicle so that the measurement area is always on the mark, continuously measures the retroreflectivity at the front of the head 6 meters, and records the data directly into the software file database. The touch panel displays a representative image of the current measured value and the marked retroreflective data. Provide a complete detailed report upon completion. In addition to the retroreflective value of the road markings, the retroreflectometer system captures active cat eyes, temperature, humidity, travel speed, GPS coordinates, pictures and voice notes, all recorded in a file.
Whether it is from a road safety perspective or a subsequent economic cost, it is a wise decision for drivers to purchase retroreflectometers.
