Traffic Count File Development for TransCAD Model Validation and Calibration |
SEMCOG has recently built a new travel demand model using TransCAD. The model calibration and
validation requires traffic count data input from numerous sources including MDOT, county road
commissions, and local communities. SEMCOG awarded us a contract to develop an efficient
process to automatically retrieve and format count data from available sources to meet the
requirements of the model calibration and validation. There were three main objectives in this project:
- Travel Forecast Model Calibration/Validation State-of-the-Practice Assessment
- Traffic Count Data Specification and Update Process
- Traffic Count File Development for the TransCAD Model

Big House Geographic Information System |
|
Few structures in Michigan ellicit more emotional response from the public than
the University of Michigan's football stadium—the Big House. So when the
renovations become necessary, a lot of eyes are focused on the plans. To help
the university in selecting the best design option, Midwestern Consulting has
created a GIS-based seating model of the stadium. The spatial model contains
information such as the exact postion of each seat and average seat width. The
model has allowed the university to consider various seating and aisle width
configurations and instantly see how they would affect the overall seating capacity.
The model can also be used in the future to create a web-based seat selection chart
to facilitate ticket sales.

Oakland County Signal System Optimization |
|
As a subconsultant to Parsons, Midwestern Consulting is working on the
Signal System Optimization Phase-3 project for the Road Commission for
Oakland County. The project includes about 247 signalized intersections.
Midwestern Consulting is responsible for data collection/management and
development of a Traffic Signal GIS (TSGIS). The project is expected to
take 18 months and result in optimized signal timing, improved traffic flow
and safer intersections.

Major Street System / Traffic Plan Analysis
City of Portage |
|
While the frantic pace of development in the last decade may be slowing, it
has left many communities with the need to catch up with infrastructure
improvements to support vastly increased traffic. To meet the demands, the
City of Portage maintains a comprehensive approach to manage its transportation
system. As a part of the effort, the City is initiating a major street network
traffic study. The primary objectives of the study are to review the current
major street network, to analyze traffic and crash data, as well as to identify
transportation improvements. The study will also update the City’s Major
Thoroughfare Plan and develop Access Management Policies.

Traffic Count Database System (TCDS) |
The web-based Traffic Count Database System (TCDS)
is for management and analysis of traffic count data.
TCDS provides traffic engineers and planners with an efficient
tool to collect, input, validate, edit, and analyze traffic
count data. It facilitates direct data download from counters,
quick data retrieval and safe data storage, while eliminating
tedious manual data input that is prone to errors. It significantly
reduces the effort required to manage traffic count data and
assist you in making objective decisions.

Woodward Ave Signal Optimization |
|
As part of the FHWA Congestion Mitigation and Air Quality (CMAQ) program, MDOT is working on the
Traffic Signal Timing Optimization of the Woodward Avenue
corridor from downtown Detroit to Eight Mile Road, which consists of 51 signals. This project
website has been developed to manage relevant project data and provide MDOT and the project team
with instant access to the data and project results.

I-75 East-West Crossing Study
Gaylord, Michigan |
|
Currently, there are few options to alleviate traffic congestion in the Gaylord area and Midwestern
Consulting is tasked with traffic data collection and creating alternative traffic flow models
using the SYNCHRO computer simulation program. Unique to this project is the fact that the peak
traffic periods occur on weekends, not during the normal business week. Thus, the study must
consider the impact of significant recreational vehicle volumes and their contribution to delay
and congestion. The one year study will identify feasible alternatives for achieving improved
traffic flow in the Gaylord and surrounding township environments as local governments consider
future land use changes.

Traffic Crash Location System (TCLS) |
|
MDOT and its traffic safety partner agencies are working to improve the accuracy and timeliness
of traffic crash data to enable stakeholders to make quality traffic safety improvements. As part
of the efforts, a project to locate protested (unlocated) traffic crashes for
calendar years 2001 and 2002 is underway. A secure web-based Traffic Crash Location System
(TCLS) has been developed to improve the crash location process and data quality.

Main Street Traffic Study |
The Belleville community – Van Buren Township, the City of Belleville and Sumpter Township –
is experiencing a significant rate of growth, which is generating increased traffic and placing
a heavy burden on Main Street. The Main Street Traffic Study
is proposed to develop improvement strategies to increase corridor capacity while improving the
viability of the downtown shopping district. The project website has been developed to enhance
communication among the project team, Belleville DDA stakeholders, and the public.

Water/Sewer GIS |
|
A Water/Sewer Geographic Information System (GIS) is being developed for
the Charter Township of Augusta. The GIS contains the data of property description, tax assessment,
water sewer usage and billing. The web-based system allows users to search the data with just a web
browser. The system is secure with a password-protected mechanism. For access, please contact us.

Genesee County Traffic Signal GIS |
The Traffic Signal GIS provides the Genesee County Metropolitan Planning Commission and its partner
agencies including MDOT, Genesee County Road Commission, City of Flint and small cities with an
efficient tool to manage traffic signal and intersection data such as traffic count, timing plan,
intersection geometry, and signal hardware.

Northfield Development |
The Land GIS includes information about property ownership, assessment value, and natural features. It
is being used by Midwestern Consulting in the preparation of an Environmental Assessment of the
replacement of the interchange located at US 23 and North Territorial Road. The Land GIS also is helpful
to numerous land owners and potential developers to evaluate various development options in the 1600-acre
area around US 23 and North Territorial Road in Northfield Township, Washtenaw County, Michigan.
Public comments relating to the environmental impacts of replacing the interchange
can be sent via the email link below.
