Battle Creek Downtown Traffic Study
A comprehensive traffic study of the downtown Battle Creek, MI, area was undertaken to quantify existing traffic flow conditions and evaluate the impacts of future development and street designs. The goal was to develop a tool that could be used to support a vibrant and economically-sustainable downtown with transportation infrastructure for pedestrian, bicycle and motor vehicle traffic. Traffic and pedestrian volumes and geometric and traffic control data were collected and Synchro models for peak and off-peak conditions were developed, calibrated and validated for existing conditions. The estimated impacts of closing a half-block section of McCamly Street south of Jackson Street to make the downtown area more pedestrian-friendly indicated it was a viable alternative for current traffic volumes. The Department of Public Works is using the models to identify traffic flow problems and to optimize signals along major street corridors. Future uses include evaluating the impacts of new development and additional traffic volumes, and examining the impacts of alternative road designs such as reducing the number of traffic lanes. |

Livernois Avenue Safety Study
To improve safety and operations on the Livernois Avenue corridor from McNichols Road to Pembroke Avenue in Detroit, MI, the roadway was converted from a five-lane arterial with a center two-way, left-turn lane with direct left-turns at intersections to a narrow median boulevard with indirect left-turns at directional crossovers. A before and after safety analysis and operational study was conducted to determine the feasibility of reintroducing direct left-turns from Livernois Avenue onto five intersections. Based on the results, it was recommended that left-turns should not be reintroduced at three of the five major intersections. Left-turns, along with other improvements, were recommended at the two remaining intersections. |

Detroit Signal Modernization
Wade Trim has been working with the City of Detroit, MI, since 1999 to improve vehicle and roadway safety at more than 500 intersections. Due to a large frequency of intersections with high crash rates, the Michigan Department of Transportation teamed with the City to obtain safety funding for intersection widening and signal modernization. Traffic signal modernization projects have ranged from simple, pre-timed, two-phase intersections to multi-phase intersections with freeway service drives. LED technology was used in the design of pedestrian and vehicle traffic signals, while signal heads were updated to standard 12-inch designs. Mast-arm designs were also used in Detroit’s Central Business District, and incorporated into the facade and streetscape improvement projects in preparation for the 2006 Super Bowl. HAWK pedestrian signals were also designed and installed at two crosswalks in the Wayne State University area. |

MDOT Freeway and Non-Freeway Traffic Signing
Since 2001, Wade Trim has conducted traffic sign upgrades on more than 2,000 miles of State Trunkline roads for the Michigan Department of Transportation (MDOT). The sign projects include both freeway and non-freeway highway systems. The projects include an inventory of existing sign and support information, determining what regulatory, warning, and guide information is necessary for each intersection and along the corridor, and development of design plans and a bid package for construction of the new signs. Sign location and detailed design information is logged into MDOT's computerized Michigan Traffic Sign Inventory System (MTSIS). |

Detroit Intelligent Transportation System
The City of Detroit, MI, is implementing intelligent transportation systems (ITS) along three corridors that serve important cultural, institutional and business facilities such as the Detroit Institute of Arts, Wayne State University, Henry Ford Health System Facilities, and the General Motors Renaissance Center. Projects have incorporated ITS with the geometric, electrical, and interconnect design of more than 120 intersections along Jefferson Avenue, Warren Avenue, and the New Center commercial district. The projects have included a needs analysis, identification of proper equipment, design of hardware and field components, and daily construction management and inspection services. |
