| Abstract: | Short-term memory characteristics and drivers' safety performance are applied to locate speed limit signs.In order to explore drivers' short memory characteristics,indoor tests are carried out.Exponential model is established based on the test performance.Speed limit sign space is determined when considering short-term memory model and driving safety distance.Speed limit sign intervals on expressway is calculated according to the short-term memory model and different operation speed. |

| Keywords: | expressway sing location intervals speed limit sign short-term memory model |
