“…As mentioned earlier, several factors affect the value of WBV among drivers. Lakušić and Tkalčević Lakušić 5 examined the association between vibration and road roughness at the speeds of 80 and 40 km/h. Their results showed that at the speed of 40 km/h, vibration had a higher direct relationship with increasing roughness of road.…”

Taxi drivers are daily exposed to frequent and prolonged whole-body vibration. This can cause complications such as back pain among them. Since the vibration level depends on many factors, the present study was performed to model the impact of vehicle speed on the attributes of whole-body vibration among the Peugeot 405 taxi drivers. In this experimental study, the whole-body vibration was measured while other variables including tire pressure, engine speed, road gradient, number of passengers, and type of tire, springs, and shock absorbers had been fixed. The measurements were done according to ISO2631-1 at different speeds of 20, 40, 60, and 80 km/h. Increasing the vehicle speed caused an increase in the average value of vibration attributes including Z-axis (vertical) r.m.s. acceleration, 8-h equivalent acceleration, vibration dose value (m/s 1.75), and crest factor (P < 0.05). At the speed of 80 km/h, the average vibration dose value (17.6 m/s 1.75) exceeded the upper limit of the ISO 2631-1:1997 health caution zone (>17). Further, 8-h equivalent acceleration, at the speeds of 60 and 80 km/h, was beyond the upper limit (>0.9 m/s 2). According to the crest factor, increasing speed would cause greater vibration peaks along the Z-axis (worst-case axis). The amount of whole-body vibration is sensitive to speed changes so that urban taxi drivers who are usually driving at low speeds for inner-city transits will be exposed to a lower average value of whole-body vibration. Due to the evident effect of speed on whole-body vibration attributes, it is strongly recommended to be given full consideration to this factor in preparing vibration control plans for vehicles.

“…Now, the vehicles are often a subject of vibrations, especially while in operation. The amplitude of the vibrations could be in the order of millimeters [11] and it is therefore comparable with the aptly called mmWave wavelength. The effect of antenna vibrations is studied in [12], [13], where number of possible vibration sources is listed.…”

Functional criteria for sustainable design of urban pavementsFunctional criteria have been mostly defined in urban pavements using subjective methods, rather than by means of objective and repeatable procedures. The Whole Body Vibration, the Heart Rate Variability, and new technologies to determine the IRI (International Roughness Index), are nowadays available. For that, an analysis of available technologies is made under a PC-O (Pavements Clients-Oriented) integral perspective, including simulations with the HDM-4 computer program. The IRI criteria for speeds allowed on urban roadways, i.e. the so-called IRIcity criteria, are proposed in the paper. Funkcionalni kriteriji za održivo projektiranje gradskih kolnika Funkcionalni kriteriji na gradskim prometnicama uglavnom se definiraju subjektivnim metodama, a ne pomoću objektivnih i ponovljivih postupaka. Danas su dostupne nove tehnologije za određivanje vrijednosti indeksa ravnosti (IRI), poput metode vibracije cijelog tijela (WBV) i metode varijabilnosti srčane frekvencije. Provedene su analize dostupnih tehnologija prema cjelovitom pristupu PC-O (eng. Pavements ClientsOriented) uključujući simulacije pomoću računalnog programa HDM-4 (eng. Highway Development and Management system). U radu su predloženi IRI kriteriji za brzine dopuštene na gradskim prometnicama, takozvani IRIcity kriterij.
