TJW develops roadway lighting layouts tailored to roadway classification, operational context, and agency standards. Designs emphasize safety, uniformity, maintainability, and long-term system performance.

Services include:

• Roadway and corridor lighting design for arterials, collectors, and local streets
• Pole spacing, mounting height, and luminaire distribution optimization
• LED fixture evaluation with energy and lifecycle considerations
• Glare control, uniformity, and veiling luminance considerations
• Adaptive lighting controls and dimming strategies (where applicable)

Lighting designs are developed in accordance with IES RP-8 and applicable state and local agency criteria.

TJW provides lighting design for public and private development sites, balancing functionality, safety, aesthetics, and environmental considerations.

TJW provides:

• Parking lots and garages
• Pedestrian walkways and shared-use paths
• Parks, plazas, school campuses, and civic spaces
• Commercial, mixed-use, and institutional developments
• Wildlife corridor-adjacent

Designs consider pole placement, mounting height, light trespass, and dark-sky requirements.

Lighting performance depends on reliable electrical systems. TJW prepares technical documentation to support constructibility and coordination.

Support includes:

• Voltage drop and load calculations
• Circuiting, panel schedules, and single line diagrams for lighting systems
• Photocell, time-clock, and control strategy integration
• Utility coordination support, including service point identification and technical documentation

Photometric exhibits may be prepared as standalone studies or integrated into construction documents.

To support coordination and stakeholder communication, TJW offers BIM-ready and visualization services, including::

• Revit-based lighting and pole modeling
• 3D lighting visualizations for intersections and parking areas
• Graphics suitable for public meetings and agency presentations
• Existing and proposed conditions comparisons and studies
• Detail exhibits for advanced and accurate coordination with AEC teams

Intersections and multimodal facilities require enhanced lighting to reduce conflict risk and improve user recognition.

TJW provides:

• Intersection lighting plans for signalized and unsignalized intersections
• Crosswalk and pedestrian safety lighting with vertical illuminance evaluation
• Roundabout lighting for approaches, circulatory roadways, and exits
• Bikeway, trail, and mid-block crossing illumination
• Pedestrian-scale and bollard lighting where appropriate

Designs emphasize contrast, visibility, and glare control to support drivers, pedestrians, and cyclists.

Robust photometric analysis is a core component of TJW’s lighting services and supports code compliance, design verification, and agency review.

Capabilities include:

• 3D photometric modeling using industry-standard software
• Horizontal and vertical illuminance calculations
• Uniformity and glare evaluation
• Existing and proposed conditions comparisons and studies
• Compliance with IES, Caltrans, ANSI, and local agency standards

Photometric exhibits may be prepared as standalone studies or integrated into construction documents.

TJW prepares objective lighting studies to support planning, compliance, and decision-making.

Services include:

• Lighting Analysis Studies (LAS)
• Existing lighting assessments and field measurements
• Compliance evaluations against IES and municipal standards
• Glare, spill light, and light trespass investigations
• Safety lighting assessments for high-crash corridors and intersections
