1. A traffic monitoring system comprising:
a storage device that stores a program; and
a hardware processor,
wherein the hardware processor executes the program stored in the storage device, thereby:
acquiring a position of a mobile object based on information from a detection device for detecting the position of the mobile object;
generating information on a density distribution in which index values having a distribution according to the position of the mobile object are superimposed on one another for a plurality of mobile objects;
predicting whether a target mobile object is likely to enter a gap between two of the mobile objects based on a temporal change in density value indicated by the information on a density distribution; and
estimating a trajectory and acceleration at a time when the target mobile object passes through the gap based on a gradient of the density value.
