Circle 927 Inventory tracking software The MUTCD requires municipalities to implement an asset-management system beginning in 2012, so Traffi c & Parking Control Co. (TAPCO) came up with DataLink and SignIt inventory tracking software. DataLink fi eld soft- ware collects information from the Ret- roSign GR3 retrorefl ectometer or from a manual inspection of the location, identity, sheeting and retrorefl ectivity of signs in the fi eld. SignIt inventory tracker holds a history of installation, maintenance, incident reports, work orders and assignments. Traffi c robot Tests prove that the Traffi c Robot can be seen from much greater distances than ordinary signs, according to Traffi c Robots LLC. The device has fl ashing LEDs and arms that wave continuously for attention. It is laminated in high- intensity refl ective orange sheeting. The unit is available with a solar panel, plus long-life batteries, so it can store enough energy to run 120 hours. The Traffi c Ro- bot is light enough for two people to lift into a truck or for one person to wheel into place. Pavement marker The Solar Vision 2 pavement marker Circle 928 is up to 10 times as visible as a stan- dard refl ective raised pavementmarker, because it uses light-emitting diodes (LEDs) instead of retrorefl ective materi- als. It has a solar collector to capture the energy needed to power the LEDs. The maker of the Solar Vision 2, Lightspeed Road Solar, a startup company based in Westminster, Colo., said the marker won’t dim, break or dislodge from its place embedded in the pavement. It will function for up to 330 hours on a charge, and with a profi le of only 2.5 mm above Circle 929 the pavement, it will stand up to being driven over by a steel snowplow blade. It needs eight hours in full sunlight to build a complete charge, but it will recharge even in low light. Circle 930 Circle 785 Circle 784 ROADSBRIDGES.com 65
