1. A system comprising:
an interface system configured to receive data from a railroad system that manages a railroad running parallel to a first roadway;
a plurality of sensor devices positioned in a fixed location relative to the first roadway and a second roadway, wherein the first roadway is a dedicated lane proximate to the second roadway and a sensor device from the plurality of sensor devices is configured to:
detect one or more autonomous vehicles in a first field of view on the second roadway, and for each detected autonomous vehicle that is likely to access the first roadway:
generate first sensor data for the detected autonomous vehicle;
transmit, to one or more sensor devices from the plurality of sensor devices on the first roadway, a request to generate second sensor data for the first roadway;
receive second sensor data from the one or more sensor devices of the plurality of sensor devices monitoring activities on the first roadway;
generate, based on the first sensor data and the second sensor data, observational data that describes an environment at a portion of the first roadway monitored by the one or more sensor devices;
determine an instruction indicating to allow the detected autonomous vehicle to access the first roadway based on the generated observational data; and
transmit the instruction to the detected autonomous vehicle to navigate onto the first roadway from the second roadway while the detected autonomous vehicle traverses the second roadway.
