In order to determine a reasonable length for left-turn lanes, we observed vehicles' speeds on a selected left-turn lane set up with a new concept on a second-class highway and obtained speed data of a normal section, main lane taper start point and split point. Then, we analyzed the data by means of descriptive statistics analysis, the paired-samples T test and ANOVA. The results showed that the length of a left-turn lane could be shorter without compromising comfort and safety. The speed used to determine the length of main lane taper could be reduced by 5%, and the speed used to determine the deceleration length could be reduced by 15%.
