Abstract: Example embodiments are directed to systems and methods for providing pickup point assistance. In example embodiments, a network system uses data received from one or more sensors to detect a location of a user that is requesting a transportation service. The network system also tracks, a driver along a route to the pickup point. Based on the tracking, an estimated time of arrival (ETA) of the driver at the pickup point is determined. Using the location of the user and the ETA of the driver, the network system performs analysis to determine whether an issue exists that affects the rider arriving at the pickup point on time to meet the driver. Based on the analysis, a notification to the user regarding the issue is automatically presented, whereby the notification is displayed on a device of the user.
