Transportation
The transportation practice at Timmons Group includes professional
civil engineers, designers and planners experienced in providing transportation
solutions to state and local governments. Our projects have ranged
from neighborhood sidewalk and bike lane improvements to interstate
interchanges, from the paving of rural county roads to the widening
of major urban arterials. Timmons Group’s focus has been on
highway design, traffic engineering and transportation planning.
Our civil engineering design professionals have a significant amount
of roadway design experience, including many locally-administered,
state-funded projects. Timmons Group provides complete in-house civil
engineering design services, including surveying, roadway and intersection
layout, digital terrain modeling, hydrologic studies and hydraulics,
environmental permitting, stormwater management, public hearing presentations,
traffic control plans, utility adjustment design and/or coordination,
pedestrian and bicycle facilities and construction administration
and inspection.
Our traffic engineering group provides traffic signal design services
for state and local governments as well as private clients. Our staff
has experience in analyzing the operation and timings of isolated
and coordinated traffic signal systems. Timmons Group is knowledgeable
of the latest equipment available for safe and dependable signal operations
and incorporates this knowledge into our designs.
Our transportation planning staff has significant experience in the
preparation and review of transportation plans, corridor studies and
traffic impact analyses. Timmons Group’s experience includes
the evaluation of major commercial, residential, institutional and
urban redevelopment projects for both public and private sector clients.
This experience includes traffic data collection, forecasting of traffic,
assessment of intersection and roadway geometrics, capacity and safety
analysis, access management and preliminary roadway design. Traffic
simulation and analysis tools allow our staff to analyze a variety
of situations – and then demonstrate the results to our clients,
reviewing agencies and the public in a visual and easily understandable
format.

US Route 17 Improvements
Chesapeake, VDOT
This project involved the preparation of complete right of way
and construction plans for the relocation and widening of 11.5
miles of US Route 17 from a two-lane to four-lane divided roadway.
The existing two-lane roadway runs parallel to the Great Dismal
Swamp Canal, owned and controlled by the US Army Corps of Engineers.
Potential impacts to the Canal and adjacent wetlands precluded
the opportunity to widen the roadway on its existing alignment.
Other critical design constraints included the flat topography
and the environmental sensitivity of the corridor, which greatly
influenced the drainage and stormwater management design. |

Williamsburg-James City County/Thomas Nelson
Community College Warhill Tract Traffic Impact Analysis Williamsburg,
VA
This project involved assessing
the traffic impacts to US Route 60 and Centerville Road associated
with the proposed 1,450 student high school, 350,000 square
foot community college and 3,000 seat multi-sport stadium. This project included data collection (24-hour average
daily traffic counts and peak hour directional turning movement counts),
analysis of existing/no-build traffic conditions and analysis of
individual development phases leading to full build-out conditions. The
micro-simulation traffic model SYNCHRO was used to perform capacity
analyses at several impacted intersections, in addition to optimizing
the intersections’ cycle lengths and offsets. The design
recommendations and cost estimates provided were used by the client
for a subsequent PPEA proposal solicitation. |

Broad Street Traffic Signals
Richmond
The project scope
included design services for ten traffic signal upgrades in the City
of Richmond’s Central Business District.
Design services also included preparing plans for maintenance of
traffic, utility and roadway improvements. Separate construction
documents were prepared for each phase of the project. Construction
administration services included preparation of bid documents including
technical specifications and special provisions for preferred equipment. |

Government Center Parkway
Chesterfield
County, VA
This project involved the construction
of a four lane divided roadway with a 40’ raised median and round-a-bout. A lighting
plan was also included along with irrigation and landscaping. In
addition to roadway plans, drainage and utility designs were required. The
roadway will become the main entrance into the Government Center
Complex. |

US Route 58, Jonesvile Bypass
Lee County, VA
This project is part of the Route 58 Corridor Development Program established by the Virginia Department of Transportation to enhance traffic flow and economic development along the southern boundary of the state. The Jonesville Bypass is a proposed 4.5 km (2.8 miles) limited-access arterial around the Town of Jonesville with a projected traffic volume of 6,600 vehicles per day.
