Inspired by a series of fatal pedestrian traffic incidents in Santa Rosa, California in 1991, Harrison developed the first LightGuard system as a safety aid for installation at pedestrian crossings and started LightGuard Systems to produce them. A commercial pilot, Harrison was inspired by the flashing lights used as runway beacon lights. He applied this principle for crosswalk visibility and founded LightGuard Systems to produce and install systems based on the technology he developed. Lighted Crosswalk System“The experimental ‘Crosswalk Warning System’, also known as the ‘LightGuard System’ or the ‘Santa Rosa Lights’ consists of warning lights housed in a unit which is installed on the pavement adjacent to a marked crosswalk. The lights reflect out toward the oncoming traffic to warn drivers of a pedestrian’s presence.”[4] Developed with an embedded pavement flashing-light system, the LightGuard system includes flashing lights and other visual cues to influence driver behavior near pedestrian crossings. Systems may be manually operated[5] or activated automatically through electronic sensors.[6] LightGuard’s Smart Crosswalk and other Embedded pavement flashing-light systems can be powered from the electrical grid or by on-site solar power sources.[7] SafetyReports cite that studies conducted at specific locations where no traffic signal was present have shown lighted crosswalk systems like those produced by LightGuard and other manufacturers[8] increased driver awareness of crosswalks, increasing pedestrian safety.[9][10] One study calculated an increase in driver awareness of 20-95%.[11] InstallationsLightGuard has installed its eponymous system in locations throughout the US, including at the Miami International Airport and others at San Francisco City Hall[12], as well as sites in Mexico.[13] LocationThe company has offices in Sonoma County, California References1. ^{{cite web|url=http://www.pressdemocrat.com/news/2224273-181/lighting-the-way-to-safer?gallery=2339979&artslide=0 |title=Lighting The Way To Safer |last=Mason |first=Clark |date=12 November 2013 |website=Press Democrat |access-date=15 July 2017}} 2. ^{{cite web|url=https://www.surfsantamonica.com/ssm_site/the_lookout/news/News-2007/January-2007/01_30_07_Citys_Crosswalk_System_Out_of_Order.html |title=City Crosswalk System Out Of Order |last=Eriksen |first=Olin |date=30 January 2007 |website=Surf Santa Monica |access-date=5 July 2017}} 3. ^{{cite web|url=https://www.fhwa.dot.gov/publications/research/safety/15043/index.cfm |title=Investigating Improvements to Pedestrian Crossings |date=1 June 2015 |website=FHWA.DOT.Gov |access-date=5 August 2017}} 4. ^{{cite web|url=http://www.lightguardsystems.com/wp-content/uploads/2014/11/Whitlock-Weinberger-Report-1998.pdf |title=An Evaluation of a Crosswalk Warning System Utilizing In-Pavement Flashing Lights |date=1 January 1998 |website=lightguardsystems |access-date=25 July 2017}} 5. ^{{cite web|url=https://www.longislandadvance.net/2493/Lights-art-action |title=Lights Art Action |last=Leuzzi |first=Linda |date=22 October 2015 |website=Long Island Advance |access-date=12 July 2017}} 6. ^{{cite web|url=http://honolulu.legalexaminer.com/automobile-accidents/the-pedestrian-crosswalk-safety-chronicles-innovative-solution-for-crosswalk-safety/ |title=The Pedestrian Crosswalk Safety Chronicles |last=Parsons |first=Wayne |date=6 May 2009 |website=Honolulu Legal Examiner |access-date=21 July 2017}} 7. ^{{cite web|url=http://amarillo.com/news/local-news/2017-05-24/amarillo-s-rock-island-rail-trail-get-makeover |title=Amarillo’s Rock Island Rail Trail to Get Makeover |last=Montes |first=Bianca |date=24 May 2017 |website=Amarillo |access-date=27 May 2017}} 8. ^{{cite web|url=https://www.surfsantamonica.com/ssm_site/the_lookout/news/News-2007/January-2007/01_30_07_Citys_Crosswalk_System_Out_of_Order.html |title=City Crosswalk System Out Of Order |last=Eriksen |first=Olin |date=30 January 2007 |website=Surf Santa Monica |access-date=5 July 2017}} 9. ^{{cite web|url=http://www.27east.com/news/article.cfm/East-Hampton-Village/412797/Smart-Crosswalks-Headed-To-East-Hamptons-Main-Street |title=Smart Crosswalks Headed To East Hamptons Main Street |last=Garrison |first=Virginia |date=14 February 2012 |website=27East |access-date=7 July 2017}} 10. ^{{cite web|url=https://elsemanario.com/motor/10522/cuales-son-las-causas-de-los-accidentes-viales-en-temporada-navidena/ |title=Cuales Son Las Causas De Los Accidentes Viales En Temporada Navidena |date=17 December 2013 |website=Elsemanario |access-date=19 July 2017}} 11. ^{{cite web|url=http://www.lightguardsystems.com/wp-content/uploads/2014/11/Whitlock-Weinberger-Report-1998.pdf |title=An Evaluation of a Crosswalk Warning System Utilizing In-Pavement Flashing Lights |date=1 January 1998 |website=lightguardsystems |access-date=25 July 2017}} 12. ^{{cite web|url=http://www.pressdemocrat.com/news/2224273-181/lighting-the-way-to-safer?gallery=2339979&artslide=0 |title=Lighting The Way To Safer |last=Mason |first=Clark |date=12 November 2013 |website=Press Democrat |access-date=15 July 2017}} 13. ^{{cite web|url=http://www.elarsenal.net/2014/03/26/16-atropellados-diariamente-en-el-df/ |title=Atropellados Diariamente |date=26 March 2014 |website=Elarsenal.net |access-date=19 July 2017}} 2 : Pedestrian safety|Road traffic management |
