Evaluation the Effect of Texting on Driving Performance Using a Driving Simulator

There is evidence that driver distraction is one of the major causes of vehicle accidents. One of the key factors that can affect people's driving performance drastically, is texting. Therefore, the purpose of this study is to determine the effects of texting on driving functions using a driving simulator.

This study was conducted on 80 students ranging from the ages of 20 to 40 and using a class 2 simulator. To check the performance of the drivers, reaction time variables, lane lateral deviation of the car, speed control, were used in two modes of driving without texting and driving while texting. The main scenario of the study consisted of driving a distance of 20 km on a highway.

The average momentary lane lateral deviation of the car for drivers in two stages without texting and while texting, was 0.88 and 1.36 meters, respectively, which had a statistically significant difference (P<0.001). Also, the average reaction time for drivers in the two stages without texting and while texting was 1.23 and 1.52 seconds respectively, which had a statistically significant difference (P<0.001). Furthermore, the average speed for the drivers in the two stages was 35.12 and 34.04 m/s, respectively, which had a statistically significant difference (P=0.020).

It is indicated that texting while driving has a negative impact on driving performance. The results of this study have direct consequences for drivers who are involved in this type of distracting behavior while driving, therefore it is important and essential for drivers to be aware of the impact of using cell phones while driving on driving performance.
