Vehicle with spray control system and method

A method, comprising:

• obtaining environmental information associated with an environmental feature adjacent to a vehicle, the environmental information including one or more of a type of vegetation of the environmental feature, a curve or grade of a route on which the vehicle is traveling, a direction of wind, a speed of the wind, or a distance from the vehicle to the environmental feature;
• selecting at least one spray nozzle from a plurality of spray nozzles of a dispenser centrally positioned onboard a self-propelled platform, wherein the self-propelled platform is coupled to the vehicle, and wherein the self-propelled platform is configured to move relative to the vehicle;
• dispensing a composition onto at least a portion of the environmental feature adjacent to the vehicle, wherein the composition is dispensed from the at least one spray nozzle;
• and
• advancing the self-propelled platform relative to the vehicle and based at least in part on the environmental information.

A system, comprising:

• a self-propelled platform comprising at least one wheel assembly and a coupling device, wherein the at least one wheel assembly is configured to engage at least one rail of a vehicle to advance the self-propelled platform relative to the vehicle, and wherein the coupling device is centrally positioned on a floor of the self-propelled platform;
• a dispenser configured to dispense a composition onto at least a portion of an environmental feature adjacent to the vehicle, the dispenser further configured to be received by the coupling device to couple the dispenser to the self-propelled platform and to keep the dispenser in a central position on the floor of the self-propelled platform;
• and
• a controller configured to operate one or more of the vehicle, the self-propelled platform, or the dispenser based at least in part on the environmental feature and a curve of a route on which the vehicle is traveling, wherein the controller is configured to control the dispenser to spray a first quantity of chemical composition from a first side of the self-propelled platform and a second quantity of chemical composition from a second side of the self-propelled platform during travel of the vehicle on the curve, wherein the first and second quantities are different, and wherein the first and second sides are different.
