BURLINGTON STREET MEDIAN PROJECT

Project Description: In response to pedestrian fatality crashes, Anderson-Bogert worked with Hoffman Design for the City of Iowa City to prepare a concept study for a median pedestrian refuge on Burlington Street in downtown Iowa City. The focus of the study was pedestrian safety and aesthetics.
The consultant team worked with a steering committee to develop median concepts that would channel pedestrians to the signalized intersections and discourage mid-block crossings. Because Burlington Street carries 25,000 vehicles per day, significant traffic analysis and modeling were necessary to estimate the capacity effects of the new median. Other considerations were private driveway access, emergency vehicle access, bicycle accommodations, and redevelopment of private property along the corridor.




 

 

Corridor Metropolitan Planning Organization (CMPO)

METROPOLITAN AREA PROJECTS STUDY

Project Description: Feasibility studies of eight (8) urban corridors in Marion, Hiawatha, and Cedar Rapids to identify short term and long term traffic operational issues and solutions. The corridors were selected for study based on CMPO computerized traffic model output identifying these corridors with high potential for future traffic operational problems. This project included traffic operational studies of seven urban corridors within the CMPO metro area. These corridors included:

Traffic operational data were collected including mechanical traffic counts, manual intersection turning movement counts, traffic accident history, existing roadway and lane widths, intersection geometry, existing traffic signal timings and phasing. Computerized traffic operational models were developed using the Synchro and SimTraffic simulation programs based on existing traffic volumes and future projected traffic volumes provided by CMPO. Short term and long term solutions were developed for each corridor and were presented at public informational meetings for each corridor. Study data, analyses, alternatives, findings, and public comment were included in written reports for each corridor.

  

 

 

Menard's

TRAFFIC SIGNAL SYSTEM FOR MENDARD'S SITE DEVELOPMENT AT HIGHWAY 100 AND EAST POST ROAD , MARION , IOWA

Project Description: ANDERSON-BOGERT Engineers & Surveyors, inc was retained by Menard's Corporation to prepare site development plans for approximately 140 acres of property located on the northwest quadrant of Iowa Highway 100 and East Post Road in Marion , Iowa . In addition to the site plans, two new traffic signals were designed and constructed to IDOT requirements at the new site intersections of Menard's Lane and Oakbrook Lane with Highway 100. The signal installations included dilemma zone protection loops, stop bar video detection, and copper interconnect. The two signals were interconnected and coordinated with and existing traffic signal at the intersection of Highway 100 and East Post Road . Coordinated timing plans and offsets were prepared. During construction, shop drawing review and on-site assistance with plan clarifications were provided.

Project Cost: $250,000
Date Completed: Summer 2004

 

City of Cedar Rapids , Iowa

1 ST AVENUE WEST / WILLIAMS BOULEVARD FROM 8 TH AVENUE TO 13 TH STREET

Project Description: ANDERSON-BOGERT Engineers & Surveyors, Inc. was retained by the City of Cedar Rapids to prepare construction plans for the widening of 1 st Avenue / Williams Boulevard ( Iowa Highway 922/Business 151) from 8 th Avenue to 13 th Street . The project included widening the existing four lane roadway to five lanes with dedicated left turn bays at the major intersections and a two-way left turn lane between the major intersections. The existing traffic signals at 1 st Avenue intersections with 15 th Street and with 18 th Street were replaced and upgraded. A fiber optic cable interconnect between the two intersections was spliced into the existing copper interconnect that runs down 1 st Avenue/Williams Boulevard . The traffic signals were constructed in two phases. The signal poles, controllers, and fiber optic interconnect were constructed first to provide traffic signalization during the widening construction that requires removal of the existing signals. The new signals were temporarily wired overhead and used temporary video detection. The traffic signal system will be completed as part of the widening to provide stop bar loop detection and advance loops on all approaches for dilemma zone protection and data collection for the City's ACTRA Closed Loop System. The project falls under IDOT jurisdiction and was partially funded through U-STEP and 3R funding sources. The signal improvements required IDOT review and approval through New Traffic Control Device permitting process.

Project Cost: $2,080,000 (Including all improvements)
Project Completed: May 2004 Traffic Signals/September 2005 Widening

DUBUQUE STREET AND FOSTER ROAD TRAFFIC SIGNAL

Project Description: ANDERSON-BOGERT Engineers & Surveyors, Inc. was retained to design a new traffic signal on Iowa Highway 1 at the intersection of Northgate Drive . The project included a signal warrant study, survey, preliminary design, final design, utility coordination, preparation of bid documents, review of Contractor submittals/shop drawings, and preparation of applicable IDOT permits for the new signal. The signal was interconnected with an existing signal at Highway 1 and NCS Drive using a fiber optic interconnect. The project was funded jointly through City/Private Developer/U-STEP funding. to design a new traffic signal on Dubuque Street at the intersection of Foster Road . The project included preliminary design, check plans, and final plans per the IDOT Standard project development process for IDOT letting. During the design process, coordination with utilities to determine necessary relocations and power supply for the new signal was completed. Also included in the design was a temporary span wire signal for construction traffic control at the intersection of Dubuque Street with Taft Speedway while Foster Road is closed during the reconstruction of Dubuque Street . The span wire signal included stop bar video detection units that will be relocated to the permanent signal at Foster Road . The permanent signal utilizes advance loops for dilemma zone protection.

Project Cost: Bids November, 2004
