Narrative:

After landing at ZZZ, we were instructed to taxi to gate xx via the taxiway B. Upon approaching the air carrier controled alley on the east side of the concourse, we were instructed to enter the alley and taxi to gate xx via the west lead-in line following an air carrier B757 which was inbound to a gate. We began to enter the alley at a distance which was close behind the B757, yet far enough behind it to be prudent regarding potential jet blast. We were operating with anti-collision beacons on top and bottom of aircraft, navigation lights, the tail logo lights, and we believe that we had the taxi light on. Entering the alley, our speed was approximately 5 mph and was limited by the progress of the B757. Shortly after crossing the ground vehicle access road, while directly abeam the emb parked at gate xx, first officer alerted me to a maintenance van which had rapidly broken the plane of our right wing approaching from the right, behind the cockpit. I applied the brakes immediately. The right wing of the aircraft and side of the van made contact on the right leading edge of the aircraft approximately 2 ft from the fuselage. The van also came into contact with several vortillons. The van was never in sight of the captain, and was only in sight of the first officer. A slight vibration was felt on the aircraft. The flight attendant was asked to stand by to evacuate/evacuation the aircraft as we investigated the severity of the damage. Ramp control was instructed to call crash fire rescue equipment. The parking brake was set immediately and #1 engine shut down. #2 was previously secured. The flight attendant surveyed the cabin for passenger injuries. None were noted. Most passenger were unaware of the contact. Many company personnel responded -- and rapidly. ZZZ ramp manager, as well as a sea of field service clerks and supervisors were on the scene rendering assistance before the fire department could respond. After instructing ground personnel to form a secure corridor of ground personnel between our aircraft and the terminal, we briefed and deplaned our passenger. I remained at the helm to coordination as our flight attendant and first officer conducted an orderly evacuate/evacuation via stairs. The driver of the van was uninjured, and made contact with myself and other company personnel to apologize for his actions.
