| ===616.27.1.3 Example Applications and Best Practices===
| |
| | |
| '''Installation and Purchasing Best Practices'''
| |
| | |
| :* For new vehicles, the purchaser of the lighting equipment should contact the ORG’s supervisor to whom the vehicle will be assigned to verify the intended use and classification of lighting. If the type of lighting necessary is not clear, the district’s “approval of exceptions” should be consulted.
| |
| | |
| :* Only persons authorized by the district and/or who are familiar with the guidelines and best practices should purchase or install fleet lighting.
| |
| | |
| :* When making a purchase, do so from a reputable vendor and require certification of the testing requirements. Also, make sure you discuss with the vendor the desired application to ensure the product is correctly utilized.
| |
| | |
| :* Before making a large purchase, ask for a demo and/or try out a small quantity to make sure they perform adequately.
| |
| | |
| :* Level 4 Lighting in excess of two rotating beacons or a 24 in. light bar should be approved by the district’s representative for approving exceptions to the minimum requirements.
| |
| | |
| :* Per the policy, no suction cup and/or magnets should be used for final installation.
| |
| | |
| :* Installation should be as “clean” as possible with no hanging or unsecured lighting inside or outside of the vehicle.
| |
| | |
| :* Beacons or mini-light bars should be installed at the highest point possible and should not be blocked by any equipment such as v-beds, luggage racks, etc.
| |
| | |
| :* For higher intensity lighting such as longer light bars, bright white LEDs, etc. the use of a dimmer function should be considered for use during night time operations.
| |
| | |
| :* The switch for the fleet lighting shall be easily accessible and visible to the operator. If possible, the switch should have an indication light to prevent the light being inadvertently left on.
| |
| | |
| :* The light should not be installed in such a fashion that could cause a reflective glare inside of the equipment/vehicle that could cause interference with its operation.
| |
| | |
| :* If possible, the switch should not utilize a factory power supply or cigarette lighter.

| ===616.27.1.5 Fleet Lighting Guidelines===
| |
| | |
| :'''Purpose:''' To increase the visibility of MoDOT vehicles by establishing an adequate minimum level of warning lighting on MoDOT equipment, to increase the safety of our employees as well as the traveling public, and improve consistency due to increased sharing between districts and divisions.
| |
| | |
| Warning light guidelines for specific MoDOT vehicles are outlined in the chart below. The intent of these guidelines is for every MoDOT vehicle to have a minimum level of fleet lighting in addition to manufacturer provided lighting. The fleet lighting level increases with the level of exposure.
| |

| |
| | |
| :* All vehicles and equipment purchased after July 1, 2013 should comply with these guidelines. Vehicles requiring fleet lighting repairs will be upgraded to comply with these guidelines depending on remaining life of the vehicle.
| |
| | |
| :* All lighting should meet SAEJ595 or SAE J845 Class 1 standard, verified by an AMECA (Automotive Manufacturers Equipment Compliance Agency) certified lab.
| |
| | |
| :* All lighting equipment should be permanently attached to the vehicle, magnetic and suction type devices should be avoided. | |
| | |
| :* Newly purchased dump trucks should be equipped with the current warning light system as outlined in the [http://sp/sites/gs/fleet/Fleet%20Forms/Forms/AllItems.aspx?RootFolder=%2Fsites%2Fgs%2Ffleet%2FFleet%20Forms%2FDump%20truck%20specifications&FolderCTID=0x0120005D4CA7C339F4E140860A6FBDC76C826B&View=%7B198E4D63%2D86B2%2D4D35%2DBE1F%2D3D30B88B30F8%7D Dump Truck Specifications]. Existing dump trucks requiring retrofitting or repairs to the lighting system should comply with the current Dump Truck Specifications if the vehicle will remain in the fleet for at least one year.
| |
| | |
| :* The manufacturer must approve supplemental lighting to any mobile attenuator.
| |
| | |
| :* Specialty vehicles used in mobile operations should have 360 degree coverage with self-contained LED units using mounting specifics dictated by the physical characteristics of the vehicle. Examples may include striper trucks, sweepers, ARAN vans, etc.
| |
| | |
| :* '''Lighting purchases that exceed the recommended minimum levels should have management approval (District Engineer/division head or District Engineer's/division head's designee).''' Examples may include vehicles and equipment related to incident response, Emergency Response, traffic signal operations, vehicles placed in high traffic conditions found in urban areas, etc.
| |
| | |
| :* Emergency Response vehicles have standardized lighting and equipment that has been established in the [https://modotgov.sharepoint.com/:b:/r/sites/SM/Incident%20Management/Documents/Stability_Guidance%20Documents/SOP-SOG/Current%20Approved%20State%20ER%20SOG/ER%20SOG%20October%202021%20_%20211001-rev.pdf?csf=1&web=1&e=3W52vM Emergency Vehicle SOP] and a [https://modotgov.sharepoint.com/:b:/r/sites/SM/Incident%20Management/Documents/Stability_Guidance%20Documents/SOP-SOG/Current%20Approved%20State%20ER%20SOG/ER%20SOG%20October%202021%20_%20211001-rev.pdf#page=16 standardized Emergency Vehicle Decal Package] that has been approved by Senior Management and shall not be deviated from.
| |
| | |
| :* Conspicuity tape should be used on pickups and SUVs for additional visibility. | |
| | |
| The research project NCHRP 13-02 was undertaken to evaluate the effectiveness of warning lights on roadway maintenance vehicles with the goal of establishing guidelines for the application of the lighting system on the vehicle. The research was done in two efforts. The first was an evaluation of the lighting parameters that define the performance in terms of glare and vehicle detectability. The second was an evaluation of the lighting systems in adverse weather and in a dynamic setting. The following recommendations and considerations come from the NCHRP 13-02 report.
| |
| | |
| :''Light Source:'' Because the spectral output of the source is very pure, solid-state LED sources seem to provide a benefit with some colors. LED sources also provide an equivalent amount of light at reduced wattage that may be beneficial to the vehicle in terms of electrical system loading.
| |
| | |
| :''Color:'' It is recommended that amber, or a combination of amber and white, lighting be used on maintenance vehicles, with amber being the predominant color.
| |
| | |
| :''Flash Pattern:'' It is recommended that the predominant light pattern be flashing. A pattern which alternates from one side of the vehicle to the other is preferable to one in which lights on both sides of the vehicle are flashing at the same time. It is also recommended that a slower flash frequency be used, since this will give a higher response to the longer light pattern than a short flash. A flash pattern such as a double flash or a pattern, similar to a rotating beacon, will provide an appearance that enables vehicle identification and should improve response.
| |
| | |
| :''Light Positioning:'' Lights should be placed high on vehicle and away from the taillights to improve vehicle identification distance.
| |
| | |
| :''Intensity Requirements:'' Using too many lights or lights with too high an effective intensity may impede the ability of other drivers to detect a pedestrian.
| |
| | |
| :Since most maintenance vehicles are used both in the day and at night, a system that dims the lighting for nighttime operation could be important.
| |
| | |
| The standards and/or reports referenced in the development of the above guidelines include:
