[Ord. 84-247 § 6.1]
All official traffic control devices shall conform to the manual and specifications required by state law and approved by the Iowa State Department of Transportation. All traffic control devices so erected and not inconsistent with the provisions of the manual or state law or this ordinance shall be official traffic control devices.
[Ord. 84-247 § 6.2]
No provision of this ordinance for which official traffic control devices are required shall be enforced against an alleged violator if at the time and place of the alleged violation an official traffic control device has not been erected. Whenever a particular section does not state that official traffic control devices are required, such section shall be effective even though no devices are erected or in place.
[Ord. 84-247 § 6.3]
A. 
Whenever official traffic control devices are placed in position approximately conforming to the requirements of this title, such devices shall be presumed to have been so placed by the official act or direction of lawful authority, unless the contrary shall be established by competent evidence.
B. 
Any official traffic control device placed pursuant to the provisions of this title and purporting to conform to the lawful requirements pertaining to such devices shall be presumed to comply with the requirements of this title, unless the contrary shall be established by competent evidence.
[Ord. 84-247 § 6.4]
A. 
For the purpose of this section "stop at the official traffic control signal" means stopping at the first opportunity at either the clearly marked stop line or before entering the crosswalk or before entering the intersection.
B. 
Official traffic control signals consisting of colored lights or colored lighted arrows shall regulate vehicle and pedestrian traffic in the following manner:
1. 
A "steady circular red" light means vehicular traffic shall stop. Vehicular traffic shall remain standing until a signal to proceed is shown or vehicular traffic, unless prohibited by a sign, may cautiously enter the intersection to make a right turn from the right lane of traffic or a left turn from a one-way street to a one-way street from the left lane of traffic on a one-way street onto the left-most lane of traffic on a one-way street. Turns made under this paragraph shall be made in a manner that does not interfere with other vehicular or pedestrian traffic lawfully using the intersection. Pedestrian traffic facing a steady circular red light shall not safely cross the roadway without interfering with any vehicular traffic.
2. 
A "steady circular yellow" or "steady yellow arrow" light means vehicular traffic is warned that the related green movement is being terminated and vehicular traffic shall no longer proceed into the intersection and shall stop. If the stop cannot be made in safety, a vehicle may be driven cautiously through the intersection. Pedestrian traffic is warned that there is insufficient time to cross the intersection and any pedestrian starting to cross the roadway shall yield the right-of-way to all vehicles.
3. 
A "steady circular green" light means vehicular traffic may proceed straight, turn right or turn left through the intersection unless otherwise specifically prohibited. Vehicular traffic shall yield the right-of-way to other vehicular and pedestrian traffic lawfully within the intersection.
4. 
A "steady green arrow" light shown alone or with another official traffic control signal means vehicular traffic may cautiously enter the intersection and proceed in the direction indicated by the arrow. Vehicular traffic shall yield the right-of-way to other vehicles and pedestrians lawfully within the intersection.
5. 
A "flashing circular red" light means vehicular traffic shall stop and after stopping may proceed cautiously through the intersection yielding to all vehicles not required to stop or yield which are within the intersection or approaching so closely as to constitute a hazard, but then may proceed.
6. 
A "flashing yellow" light means vehicular traffic shall proceed through the intersection or past such signal with caution.
7. 
A "don't walk" light or symbol is a pedestrian signal which means that pedestrian traffic facing the illuminated pedestrian signal shall not start to cross the roadway in the direction of the pedestrian signal, and pedestrian traffic in the crossing shall proceed to a safety zone.
8. 
A "walk" light or symbol is a pedestrian signal which means that pedestrian traffic facing the illuminated pedestrian signal may proceed to cross the roadway in the direction of the pedestrian signal and shall be given the right-of-way by drivers of all vehicles.
[Ord. 84-247 § 6.5]
No person shall place, maintain, or display upon or in view of any person upon a street any sign, signal, marking, or device which purports to be or is an imitation of or resembles an official parking sign, curb or other marking, traffic control device or railroad sign or signal, or which attempts to direct the movement of traffic, or which hides from view or interferes with the effectiveness of any official traffic control device or any railroad sign or signal, if such sign, signal, marking, or device has not been authorized by the City traffic engineer and no person shall place or maintain any traffic sign or signal bearing thereon any commercial advertising.
Every such prohibited sign, signal, or marking is hereby declared to be a public nuisance and the City Administrator is hereby empowered to remove the same or cause it to be removed without notice.
[Ord. 84-247 § 6.6]
Whenever official traffic control devices are placed in position approximately conforming to requirements of this title such devices shall be presumed to be in full force and effect at all times unless the hours during which the device is in effect are so stated on the device.
[Ord. 2009-337 § 1; Ord. 2005-361; Ord. 2004-35]
A. 
General. The City of Davenport, in accordance with the police powers authorized it by the state of Iowa for governing safe traffic flow, may deploy, erect or cause to have erected an automated traffic enforcement system for making video images of vehicles that fail to obey red light traffic signals at intersections designated by the City Administrator or his designee or fail to obey speed regulations at other locations in the City. The system may be managed by the private contractor that owns and operates the requisite equipment with supervisory control vested in the City's police department. Video images shall be provided to the police department by the contractor for review. The police department will determine which vehicle owners are in violation of the City's traffic control ordinances and are to receive a notice of violation for the offense.
B. 
Definitions.
1. 
AUTOMATED TRAFFIC ENFORCEMENT SYSTEM – Shall mean an electronic system consisting of a photographic, video, or electronic camera and a vehicle sensor installed to work in conjunction with an official traffic controller or police department employee to automatically produce photographs, video or digital images of each vehicle violating a standard traffic control device or speed restriction.
2. 
VEHICLE OWNER – Shall mean the person or entity identified by the Iowa Department of Transportation, or registered with any other state vehicle registration office, as the registered owner of a vehicle.
C. 
Offense.

The vehicle owner shall be liable for a fine as imposed below if such vehicle crosses a marked stop line or the intersection plane at a system location when the traffic signal for that vehicle's direction is emitting a steady red light or red arrow.
2. 
The vehicle owner shall be liable for a fine as imposed below if such vehicle travels at a speed above the posted speed limit.

3. 
A recipient of an automated traffic citation may dispute the citation by requesting an issuance of a municipal infraction citation by the police department. Such request will result in a required court appearance by the recipient and in the scheduling of a trial before a judge or magistrate at the Scott County Courthouse. The issuance of a municipal infraction citation will cause the imposition of state mandated court costs to be added to the amount of the violation in the event of a guilty finding by the court.
4. 
If a recipient of a notice of violation does not request the issuance of a municipal infraction citation to dispute the alleged violation by contested proceedings before a judge or magistrate within the time specified within the notice of violation, the recipient will be deemed to have waived his right to dispute the violation, and the violation will be admitted with the civil penalty being due and owing to the City. A notice of intent to default will be mailed to the recipient at least 10 days prior to the deadline for contesting.
