| ==236.5.29 License Plate Readers==
| |
| Automated License Plate Readers (LPRs) and Pan-Tilt-Zoom cameras (PTZs) are an increasingly popular way for law enforcement to better locate vehicles associated with criminal activity. The deployment of these devices on Commission right of way require FHWA approval and shall not create a safety risk for the traveling public or interfere with MoDOT’s ability to maintain and operate the transportation system.
| |
|
| |
| The general process for LPR and PTZ requests is outlined in [[:Category:941_Permits_and_Access_Requests#941.10_Automated_License_Plate_Readers_and_Pan-Tilt-Zoom_Cameras|EPG 941.10]].
| |
|
| |
| It is the requesting law enforcement agency’s responsibility to contact MoDOT’s local traffic permit specialist to initiate the permitting process, after approval from Department of Public Safety (DPS) has been received. The local district traffic representative will work with the applicant through the permitting process.
| |
|
| |
| Once the district traffic staff determine the LPRs or PTZs are eligible to be deployed on Commission right of way, the district traffic staff will forward the drafted permit via the permit database to Central Office Right of Way (COROW). CO ROW will then gather the following items to seek FHWA approval:
| |
| * Cost estimate including the device and pole, and fair market value of the device location
| |
| * Environmental clearance - [https://epg.modot.org/forms/general_files/DE/RW/Categorical_Exclusion_Review_Form.pdf categorical exclusion approval]
| |
|
| |
| Once COROW gathers the items listed above, they will include the following items in their submittal to FHWA for approval:
| |
| * [https://epg.modot.org/forms/general_files/DE/RW/FHWA_LPR_NonHighway_Use_Request_Letter FHWA LPR Nonhighway Use Request Letter]
| |
| * DPS approval letter
| |
| * Roles and Responsibilities document
| |
| * Plans including type and location of equipment to be installed
| |
|
| |
| Upon receiving FHWA approval, COROW will upload the FHWA approval documentation in the permit database and notify the district traffic staff they may proceed with issuing the permit. If FHWA does not approve, the permit cannot be issued.

|
| |
| Automated License Plate Readers (LPRs) and Pan-Tilt-Zoom cameras (PTZs) are an increasingly popular way for law enforcement to better locate vehicles associated with criminal activity. These high-tech devices allow law enforcement agencies to compare plate numbers against those of stolen vehicles and vehicles driven by individuals with expired licenses, an active warrant, or involved with terrorist activities.
| |
|
| |
| The deployment of these devices on Commission right of way shall not create a safety risk for the traveling public or interfere with MoDOT’s ability to maintain and operate the transportation system. All costs associated with the installation and maintenance of the LPRs and PTZs will be the responsibility of the applicant. The following guidance applies to any LPR or PTZ installed on Commission right of way.
| |
|
| |
| ===941.10.1 Approval Process===
| |
| The general process for LPR and PTZ requests are outlined in the [[media:941.10-LPR Installations_06-23.pdf|LPR Flowchart]]. Law enforcement agencies must request approval, in writing, for deploying LPRs and PTZs from the [https://dps.mo.gov/dir/ Director of the Department of Public Safety]. Requests are to be on the law enforcement agency letterhead and emailed to the Department of Public Safety at [mailto:dpsinfo@dps.mo.gov dpsinfo@dps.mo.gov].
| |
|
| |
| The Department of Public Safety (DPS) provides approval for the use of LPR and PTZ devices. MoDOT only facilitates the administration of work by others on Commission right of way. [[#941.6 Request for a Permit to Perform Work on MHTC’S Right of Way|MoDOT’s permitting process]] will be followed for the constructability and maintenance of the devices to ensure the safety of the traveling public. If an issue is identified through our normal permitting process and cannot be resolved, a permit for this work will not be issued.
| |
|
| |
| It is the requesting law enforcement agency’s responsibility to contact MoDOT’s local permit specialist to initiate the permitting process, after approval from DPS has been received. Contact information for MoDOT’s local permit specialists can be found using the District Permit Maps.
| |
|
| |
| The local district traffic representative will work with the applicant through the permitting process. The permit request submittal must include:
| |
| * An aerial image, or map, depicting all the individual LPR locations included in the submittal.
| |
| * An aerial image for each LPR location included in the submittal clearly showing where the proposed installation with respect to the roadway and other structures on the right of way.
| |
| * A set of drawings, or plans, showing the hardware and their installation details proposed on the right of way, which must be signed and sealed by a Missouri Professional Engineer (P.E.).
| |
| * This applies to stand alone installations as well as installations on approved existing structures on right of way, such as signal and sign truss uprights.
| |
| * Executing a Roles and Responsibilities document to specifically address the expectations of maintaining the devices being installed.
| |
| * A plan to provide electricity to the equipment as well as retrieving data from the equipment.
| |
| * A traffic control plan for any proposed work on the right of way to notify and guide motorists safely through the activity area.
| |
| * A surety deposit or performance bond to insure satisfactory work, accepted by MoDOT.
| |
|
| |
| A separate permit may be provided for the applicant, or their consultant, to access the right of way to collect information needed to develop a set of plans for installing the devices.

| |
|
| |
| ===941.10.2 Location===
| |
| When receiving a request, the district traffic staff will work with the law enforcement agency to determine if there are acceptable locations for the proposed installations off MoDOT right of way. If there are no appropriate locations off of right of way, the district traffic staff will work with the agency to determine if the LPRs and PTZs requested can be deployed on Commission right of way.
| |
|
| |
| LPR and PTZ installations on Commission right of way shall only monitor traffic on MoDOT roadways and shall not be used to monitor off system roadways, such as county, city, or private facilities.
| |
|
| |
| Once the district traffic staff determine the LPRs or PTZs are eligible to be deployed on Commission right of way, the district traffic staff will forward the drafted permit via the permit database to Central Office Right of Way (COROW). See section 236.5.29 for COROW’s review and process for requesting FHWA’s approval.
| |
|
| |
| Upon receiving FHWA approval, COROW will upload the FHWA approval documentation in the permit database and notify the district traffic staff they may proceed with issuing the permit. If FHWA does not approve, the permit cannot be issued.
| |
|
| |
| ====941.10.2.1 LPR and PTZ Non-Permanent Installations - Speed Enforcement Trailers====
| |
| The only form of non-permanent structure that LPR and PTZ devices may be deployed on, when placed on Commission right of way, are speed trailers. However, speed trailers shall only be deployed for the primary purpose of speed enforcement and not for the primary purpose of deploying LPR and PTZ devices. When speed trailers are deployed, the electronic speed message must be active and the unit deployed and delineated in accordance with [[907.8 Speed Trailers Deployed by Others|EPG 907.8 Speed Trailers Deployed by Others]].
| |
|
| |
| ====941.10.2.2 LPR and PTZ Permanent Installations====
| |
| To ensure LPR and PTZ devices do not represent an added risk to the traveling public, there are defined installation locations which are acceptable on Commission right of way. Acceptable installation locations include:
| |
| * Only deployed on the right side of the roadway outside of the shoulder.
| |
| * On MoDOT traffic signal upright poles, except in instances where deployment will interfere with other devices already attached to the pole.
| |
| * On MoDOT overhead sign truss upright poles.
| |
| * On any non-breakaway structure owned by a third party, with the written permission of the third party.
| |
| * On independent support behind barrier (installed and maintained by requesting agency or their LPR vendor) in accordance with the guidance in [[:Category:941_Permits_and_Access_Requests#941.10.2.2.3_LPRs_and_PTZs_Installed_on_New_Stand-Alone_Structures|EPG 941.10.2.2.3]].
| |
| * On independent breakaway support that has been crash tested by the LPR vendor and approved by MoDOT. See [[:Category:941_Permits_and_Access_Requests#941.10.2.2.3_LPRs_and_PTZs_Installed_on_New_Stand-Alone_Structures|EPG 941.10.2.2.3]] for approved systems.
| |
|
| |
| Locations where LPR and PTZ devices <u>shall not</u> be installed include, but are not limited to:
| |
| * Any installation in the median / left side of a divided highway.
| |
| * Any overhead location.
| |
| * On any existing structure on right of way which has a breakaway design, whether it is owned by the Commission or a third party.
| |
| * Any bridge structure.
| |
| * Any location that already has a device installed.
| |
| * Any location that may interfere with MoDOT's ability to manage the transportation system.
| |
|
| |
| MoDOT does not allow the deployment of LPR and PTZ devices overhead or in the median as these locations would result in increased impact on the safety and mobility of the traveling public when performing installation and maintenance activities. LPR and PTZ devices are not permitted on any existing structure which is designed as a breakaway device on Commission right of way, regardless of ownership, as the addition of these devices could negatively impact the performance and safety of the breakaway structure.
| |
|
| |
| There are three methods identified for deploying LPR and PTZ devices on Commission right of way, all of which must be approved by MoDOT and installed under a MoDOT permit:
| |
| * LPRs and PTZs installed on MoDOT structures.
| |
| * LPRs and PTZs installed on non-MoDOT structures.
| |
| * LPRs and PTZs installed on new stand-alone structures.
| |
|
| |
| =====941.10.2.2.1 LPRs and PTZs Installed on MoDOT Structures=====
| |
| LPRs and PTZs can be attached to MoDOT’s existing traffic signal upright poles and existing sign truss upright poles upon review and approval by MoDOT.

| |
|
| |
| =====941.10.2.2.2 LPRs and PTZs Installed on non-MoDOT Structures=====
| |
| There are some structures that have been permitted on Commission right of way which are owned by other entities, such as structures for weigh station bypass equipment or utility poles. Law enforcement agencies have the option to acquire approval from the owners of the structures to utilize them as supports for their LPR and PTZ devices if they meet the following criteria:
| |
| * The structure must be reviewed and approved by MoDOT for use.
| |
| * Written permission from the owner of the structure must be acquired and supplied to MoDOT.
| |
| * Any structure which is of a breakaway design, such as roadway lighting poles or highway signs, are not acceptable support structures.
| |
| * Installation location criteria listed in [[#941.10.2.2 LPR and PTZ Permanent Installations|EPG 941.10.2.2]] also apply to these structures.
| |
|
| |
| =====941.10.2.2.3 LPRs and PTZs Installed on New Stand-Alone Structures=====
| |
| To limit the number of structures on Commission right of way, opportunities to locate the LPRs and PTZs off of right of way is the preferred option, followed by an installation location on an existing structure already on right of way. If it is determined a new stand-alone structure is required to facilitate the LPR and PTZ deployment, the following guidance shall be followed:
| |
| * The district traffic shall work with the local agency to find a location which meets the requirements outlined on the [https://epg.modot.org/forms/general_files/TS/General_LPR_Typical_Details.pdf General LPR Typical Details] or [https://epg.modot.org/forms/general_files/TS/Flock_LPR_Typical_Details.pdf Flock LPR Typical Details].
| |
| * Stand-Alone LPR and PTZ structures shall be properly spaced away from other traffic control devices, which can include but are not limited to highway signs, traffic signal, roadway lighting poles, etc.:
| |
| :○ No closer than 200 feet upstream of a traffic control device.
| |
| :○ No closer than 50 feet downstream of a traffic control device.
| |
| * Installation and maintenance access should be via adjacent private property or secondary roadways for divided highway, unless physically impossible.

REVISION REQUEST 4191
902.4.1 General (MUTCD Section 4D.01)
Support. The features of traffic control signals of interest to road users are the location, design, and meaning of the signal indications. Uniformity in the design features that affect the traffic to be controlled, as set forth in this Manual, is especially important for the safety and efficiency of operations.
Traffic control signals can be operated in pretimed, semi-actuated, or full-actuated modes. For isolated (non-interconnected) signalized locations on rural high-speed highways, full-actuated mode with advance vehicle detection on the high-speed approaches is typically used. These features are designed to reduce the frequency with which the onset of the yellow change interval is displayed when high-speed approaching vehicles are in the “dilemma zone” such that the drivers of these high-speed vehicles find it difficult to decide whether to stop or proceed.
EPG 902.23.1 contains information regarding traffic control signal operation.
Standard. The design and operation of traffic control signals shall take into consideration the needs of all modes of traffic including access and safety.
When a traffic control signal is not in operation, such as before it is placed in service, during seasonal shutdowns, or when it is not desirable to operate the traffic control signal, the signal heads shall be covered, turned, or taken down to clearly indicate that the traffic control signal is not in operation.
If a traffic control signal head is not in operation and has a yellow retroreflective strip along the perimeter of its signal backplate (see the fifth option paragraph of EPG 902.4.6), the signal head, shall be covered. If a cover is placed over a traffic control signal head that is not in operation, the entire signal head, including the signal faces and backplate shall be covered.
Standard. A traffic control signal shall control traffic only at the intersection or midblock location where the signal faces are placed.
Guidance. Midblock crosswalks should not be signalized if they are located within 1,000 feet from the nearest traffic control signal, unless supported by an engineering study or engineering judgment that indicates safe and efficient operation of the closely-spaced traffic control signals can be achieved.
Midblock crosswalks should not be signalized if they are located within 100 feet from side streets or driveways that are controlled by STOP signs or YIELD signs, unless supported by an engineering study or engineering judgment that considers restricting turning movements from the side street or driveway to eliminate conflicts with pedestrian and bicyclist movements.
Engineering judgment should be used to determine the proper phasing and timing for a traffic control signal. Since traffic flows and patterns change, phasing and timing should be reevaluated regularly and updated if needed.
Traffic control signals within ½ mile of one another along a major route or in a network of intersecting major routes should be coordinated, preferably with interconnected controller units. Where traffic control signals that are within ½ mile of one another along a major route have a jurisdictional boundary or a boundary between different signal systems between them, coordination across the boundary should be considered.
Support. Signal coordination need not be maintained between control sections that operate on different cycle lengths.
EPG 902.6.19 and EPG 913.4.9 contain information about coordination of traffic control signals with grade crossing signals.
