“…The result shows the difference of mean BRT between female and male is 0.213 s and 0.245 s for both lamps respectively, which represented the percentage improvement of 23.51% for conventional lamp and 28.62% for flashing lamp. This shows that gender had an influential part in determining the BRT, as shown in [12] which parallel with the results that indicate that males have faster BRT than females.…”

“…Table 2.2 displayed the classification of drivers' driving experience. This classification is similar to Sohrabi study [12], where the target participants are mainly UTHM Pagoh students except the experience is based on years of driving instead of distance of driving. While the range of driving experience seems small but it is appropriate with the age range of the target participants since the age of the UTHM Pagoh students is ranged from 18 to 27 years old.…”

“…This is very similar to the hypothesis of this experiment, which want to show that flashing brake lamps are better than the conventional in terms of BRT. Meanwhile, Sohrabi [12] found that gender had a significant difference in brake reaction time where women tend to have a slower brake reaction time than men. He also found that the different driving experiences also played an important part, where the experienced drivers have shorter mean BRT compared to the beginner drivers [12].…”

Rear-end collisions are one of the highest contributors to road accidents fatalities, especially motorcycles which made up to 60% of the total of accidents that occur. The reasons that trigger such accidents are careless, dangerous turning (lane splitting and weaving between vehicles) and speeding, thus causing the awareness of the following vehicles to decline. That is why this study is conducted to find out the effectiveness of flashing brake lamps compared to conventional brake lamps on motorcycles. The experiment involves the driving experience, the distance between vehicles and gender as the factors that affect the brake response time (BRT) on brake lamps. The data collected are analysed and the findings showed that driving experience can influence the BRT, where experienced drivers have faster BRT (0.575 s) compared to others, however, beginner drivers demonstrate the highest BRT reduction by 13.4% (0.123 s). The analysis of the BRT based on the distance between vehicles displayed the driver’s adaptation to flashing brake lamps. The 10 m distance has the highest BRT reduction among other distances by 18.09% (0.142 s) even though the 6 m and 8 m distances presented a quite small BRT reduction, only around 0.04 s. Gender also illustrated the biggest impact of BRT on brake lamps, where males seem to be quicker to respond than females by 23.51% and 28.62% for conventional and flashing lamps respectively. As a whole, the flashing lamps portrayed shorter BRT than the conventional lamps by 9.87% (0.074 s). thus, it is suggested that flashing brake lamps is proven to reduce the BRT of the rear drivers and are suitable for implementation on motorcycles. Therefore, this study will benefit the future improvement and increase the conspicuity of motorcycle brake lamps.

“…However, the change in the angular velocity of the leading vehicle might be insufficient to allow the following driver to judge the deceleration rate correctly [ 3 ]. Hence, other studies have focused on ways to improve the design of the brake lights to include additional information that can enable following drivers to determine the deceleration rate of the leading vehicle [ 17 , 18 , 19 , 20 ].…”

To prevent vehicle crashes, studies have proposed the use of flashing signals (brake lights or other light indicators) to improve the driver’s response time when the leading vehicle is braking. However, there are no consistent results on the ideal flashing frequency of the brake lights. This study aimed to investigate different brake light flashing frequencies to assess their impact on braking response time. Twenty-four participants aged 25 to 30 were recruited. Two driving speed environments (50 and 80 km/h), three deceleration rates (0.25, 0.6, and 1 g), and four brake light flashing frequencies (0, 2, 4, and 7 Hz) were examined. Braking response time, average braking force, and braking response time ratio were used to evaluate the driving behavior. The results showed that the braking response time and average braking force were affected by the deceleration rate in the 50 km/h driving environment. In the 50 and 80 km/h driving environments, although there were no significant differences among the three deceleration rates, the braking response time decreased by 3–7% under the flashing brake light condition. These findings can be used as a reference for safety designs as well as future studies on driving behavior.
