The invention discloses a road section travel time monitoring method and device. The method includes the following steps that: the position data of floating vehicles are sampled in one time interval, wherein the floating vehicles are matched to a monitored road section through a map matching process; actual travel time of the monitored road section in the time interval is determined according to sampled position data; the actual travel time in the time interval is inputted into a first prediction model and a second prediction model respectively, so that first predictive travel time and second predictive travel time of the monitored road section in a next time interval can be obtained; the weight coefficients of the first prediction model and the second prediction model are determined according to historic prediction errors of the first prediction model and the historic prediction errors of the second prediction model; and weighted averaging is performed on the first predictive travel time and the second predictive travel time according to the weight coefficients of the first prediction model and the second prediction model, so that final predictive travel time of the monitored road section in the next time interval can be obtained. With the road section travel time monitoring method and device of the invention adopted, the accuracy and reliability of road section travel time prediction can be improved.
