Method and system for estimating time of arrival

A method for determining an ETA relating to a target route is provided. The method includes obtaining, a target route associated with a user; determining characteristic data relating to the target route, the characteristic data including first feature data corresponding to at least a portion of the target route; obtaining an estimation model, the estimation model including a first sub-model and a second sub-model; determining first cell state data and first hidden state data based on the first feature data and the first sub-model; determining a first vector based on the first cell state data and the first hidden state data; determining second cell state data and second hidden state data based on the first vector and the second sub-model; and determining an ETA relating to the target route based on the second cell state data and the second hidden state data.
