  SANTA MONICA TRAFFIC CONTROL DEVICE INVENTORY
CLIENT:
City of Santa Monica
PROJECT DESCRIPTION:
The purpose of this project was to conduct a comprehensive Traffic Control Device Inventory and evaluation and to supply the City with the inventory loaded into a turnkey combined GIS and asset management program. The traffic control elements inventoried included traffic signs, signals, pavement and curb markings, parking meters, parking spaces, and street lights. A special effort was needed to integrate the new street light evaluation into the existing street light database. An important part of this project was the use of Windows CE-based handheld  computers for inventory and evaluation of all control devices. In addition, special programs were developed to allow the Cityís GIS database on street lights to be downloaded into the handheld computers. The existing GIS database was then used, in the field, to add evaluations of the street light system.

In addition to the above, Echelon developed specialized palmtop/handheld computer-based maintenance programs that allow maintenance staff to maintain the control device database.
 

 

TRAFFIC CONTROL DEVICE INVENTORY AND EVALUATION
CLIENT: City of Tustin
PROJECT DESCRIPTION:
In this project the Echelon team inventoried and evaluated the Cityís traffic signs, signals, pavement and curb markings, and all signs, street lights and signal poles. This data was then transferred into Asset Management Data Base programs. The team evaluated the full range of Asset Management programs available. The data bases can now be shared between/with the GIS, AutoCAD, and Asset Management team.

The inventory and evaluation part of the project involved the use of Compaq IPAQís (PPC's)loaded with the Cityís AutoCAD files translated into shp files. The city was provided the hardware and software that allows them to update the inventories over time.

 

 

     
  SANTA CLARITA SIGNS AND MARKING INVENTORY
CLIENT:
City of Santa Clarita
PROJECT DESCRIPTION:
The purpose of this project was to inventory and evaluate traffic signs and key traffic lane and curb markings in the City. It was also necessary to evaluate the full range of asset management programs that could potentially be used by the City. The inventory had to be input into a turnkey system with all hardware and software provided. The system was integrated with the Cityís GIS and City staff were trained in the use of the programs.

The inventory was obtained using crews equipped with GPS-based equipment. City staff were significantly involved in evaluating the available asset management programs and approaches. Echelon also conducted detailed assessments of existing traffic control practices and needs. As a result, special programs were developed to assist City staff in maintaining the inventory. Training was done on a continuing basis during the project to improve the ease of use of the supplied system.
 

  TRAFFIC ACCIDENT LOCATION AND MITIGATION PROGRAM
CLIENT: City of Palmdale
PROJECT DESCRIPTION:

The goal of this project was to identify the high traffic accident locations within the entire city (for both intersections and midblocks), develop and evaluate mitigation programs, recommend detailed mitigation strategies for each problem location, and provide the staff with the tools and training such that they could repeat the analysis process on an ongoing basis.

All major intersections and midblock locations were analyzed using three years of accident records. Accident rates were developed to identify the high accident locations that exhibited statistically significant performance differences. Alternative mitigations were identified and evaluated and a detailed, prioritized program of improvements presented.

The program involved extensive use of GIS for rate and location analyses and GIS was integrated with a collision diagram program that assisted in detailed site analysis.

  EVALUATION OF ADVANCED FARE PAYMENT SYSTEMS
CLIENT: FEDERAL TRANSIT ADMINISTRATION
PROJECT DESCRIPTION
:
The goal of this program was to determine the technical, operational, and economic feasibility of advanced fare payment systems for public transit. More than two thirds of the transit agencies in the American Public Transit Association (APTA) were surveyed and all pertinent technologies were reviewed. Reviews included laboratory tests and in-revenue service testing in three transit agencies, over a seven month period. The project showed conclusively that smart contact and radio-frequency proximity (RF) fare cards were not only commercially, operationally, and technically feasible, but that they also offered, in many instances, a superior solution to many of the standard fare transaction approaches.
