Traffic Engineering Services

Brudis & Associates, Inc. (BAI) provided traffic engineering services under an open-end agreement with the Maryland Department of Transportation, State Highway Administration District 7 Office. BAI successfully completed multiple transportation and traffic engineering assignments for a three (3) county area.

These projects have involved:

• Traffic Accident Analysis
• Safety and Capacity Analysis
• Pedestrian Countdown Signals
• Level-of- Service (LOS) Determinations
• Origin and Destination Studies
• Highway and Pedestrian Safety
• Synchro/SimTraffic Modeling
• Transportation System Management
• Safe Routes to School Program
• Bicycle/Pedestrian Studies
• Corridor Analysis
• Traffic Signal Warrant Studies
• Traffic Calming Evaluations
• Work Zone Traffic Control Reviews
• Highway Sign Inventory
• Pedestrian Safety Evaluations

A brief summary of projects BAI was responsible for includes:

MD Route 97/Burntwoods Road Intersection Study. BAI conducted a traffic safety and operation analysis at the intersection of MD 97 and Burntwoods Road. The study examined intersection delay and capacity, level-of-service (LOS), traffic signal warrants, crash experiences, traffic operations, field conditions and operations and geometrics, in accordance with MUTCD and AASHTO criteria.

Corridor Traffic Signal Timing Studies. BAI examined five separate corridors, involving multiple signalized intersections, to optimize traffic signal efficiencies, operations, vehicular and pedestrian safety. BAI conducted extensive peak hour field observations, geometric measurements and capacity analysis, utilizing Synchro software to determine LOS, volume to capacity ratios and signal timing recommendations.

MD 27/Westminster Street Pavement Marking Design. BAI prepared complete construction plans for pavement markings to incorporate left turn lanes along northbound and southbound MD 27 at Westminster Street.

US Route 29 at I-70 Safety Study. In response to safety concerns expressed by local citizens, BAI conduct a detailed traffic safety study at the US Route 29 and I-70 ramps and intersection, on an accelerated completion schedule. The key concerns involved unsafe traffic operations at the ramp intersection which have resulted in multiple accidents including a fatality; queuing of NB US 29 left-turn crossover lane during PM peak hour which caused a bottleneck effect and hinders motorist along the corridor and; drivers exhibiting dangerous behavior when they aggressively maneuver from lane to lane to/at the I-70 ramp merge.

MD 99 School Bus Stop Safety Study. BAI conducted a safety study along Maryland Route 99 (Old Frederick Road) in Howard County. The purpose of the project was to determine the safety of school bus stops and to complete a sight distance analysis of all public street intersections along Maryland Route 99 between Wetherburn Road and Bethany Lane/Old Mill Road for a distance of approximately 1.3 miles.

MD Route 103 Traffic Study. BAI provided a complete safety analysis and crash evaluation for the intersections of MD Route 103 at Long Gate Parkway and MD Route 103 at Long Gate Shopping Center to determine the possible need for traffic control improvements. BAI conducted field observations for the intersections, specifically focusing on the intersection geometric features, lane configuration, traffic control devices, pavement condition, peak hour traffic operation, and driver behavior.
