Linear Referencing System (LRS) for the Caltrans highway network to meet HPMS requirements

Linear Referencing System (LRS) for the Caltrans highway network to meet HPMS requirements

Challenge Caltrans needed to build a linear reference systems (LRS) to support upcoming federal Highway Performance Monitoring System (HPMS) requirements. They asked Farallon to recommend a plan to pilot development for five counties in the Sacrmento area, to meet the new HPMS standards. HPMS is a federally mandated inventory system and planning tool designed to assess the nation’s highway system. It is used for apportionment, performance measures, highway statistics,...
Farallon builds Emergency Operations Center (EOC) incident management application for MTC

Farallon builds Emergency Operations Center (EOC) incident management application for MTC

Challenge During a major disaster or event, the Metropolitan Transportation Commission (MTC) is required to activate an Emergency Operations Center (EOC) to support the needs of regional transportation agencies and the emergency management community. MTC EOC staff are responsible for collecting, analyzing, and disseminating regional transportation information that may impact local and regional emergency response decisions. In order to effectively manage unpredictable events in real time, the EOC needed...
Farallon Helps Caltrans Improve Accuracy of States County Route Postmile System

Farallon Helps Caltrans Improve Accuracy of States County Route Postmile System

Challenge The California Department of Transportation (“Caltrans”) locates points along California’s highways using a linear referencing system based on county, route (highway number) and postmile (distance along the highway centerline from the county boundary). Caltrans wanted to improve the accuracy of the county route postmile system by accurately determining locations where highways cross county lines, especially in areas where the highway repeatedly crosses county lines over a short distance...
Integrating MDOT’s business data with its geographic data using Oracle Spatial

Integrating MDOT’s business data with its geographic data using Oracle Spatial

Challenge The Michigan Department of Transportation (MDOT) is responsible for planning, designing, building and operating streets, highways, bridges, transit systems, airports, railroads and ports. MDOT used separate systems to manage the geographic data and the business data (using a linear referencing system) describing the state’s transportation network. Because, the LRS technology was not geographically referenced, MDOT’s ability to automate data validation procedures and perform real-time spatial analyses of the...
California Department of Forestry and Fire Protection for Emergency Response

California Department of Forestry and Fire Protection for Emergency Response

Challenge The California Department of Forestry and Fire Protection (CDF) was in the process of acquiring a GIS-based Computer-Aided-Dispatch (CAD) system under the State’s alternative procurement process in 2001 and sought Farallon’s GIS strategic and technical assistance. Each of CDF’s 21 statewide protection units has an all-risk Emergency Command Center that requires a fully functional, GIS-based road network capable of locating emergency situations from 911 calls. To support all...
