1. A transportation system to determine estimated time of arrival (ETA), the system comprising:

  • a data storage to store a standard time of arrival (STA) table, wherein the STA table includes an STA for a fixed stop along a fixed route and an STA for each waypoint or geo-section along the fixed route, wherein each waypoint represents a point along the fixed route and each geo-section represents a portion of a geographic area related to the fixed route; and

    at least one hardware processor to;

    determine, for a vehicle traveling on the fixed route and travelling towards the fixed stop from an origin, an actual time of arrival (ATA) of the vehicle at the waypoints or geo-sections along the fixed route between the origin and the fixed stop, wherein the ATA of the vehicle is determined based on a current location of the vehicle, and wherein the current location of the vehicle is determined by using a location sensor, wherein the location sensor is to further detect when the vehicle is adjacent to one of the waypoints, and transmit the ATA associated with the detection of when the vehicle is adjacent to the one of the waypoints;

    determine a delay at each of the waypoints or geo-sections, wherein the delay for each waypoint or geo-section is determined as a difference between the STA from the STA table for the waypoint or geo-section and the ATA of the vehicle at the waypoint or the geo-section;

    determine an ETA of the vehicle at the fixed stop, wherein the ETA is determined as a sum of the delay at each waypoint or geo-section added to the STA of the fixed stop;

    determine an ETA for each fixed stop of a plurality of fixed stops of the fixed route based on ATAs for previous fixed stops and intervening waypoints or geo-sections; and

    transmit the ETA for each fixed stop of the plurality of fixed stops of the fixed route to display a map including the fixed route and the ETA for each fixed stop of the plurality of fixed stops of the fixed route.
