Services:

Precision Systems, Inc. (PSI) is leading multimodal planning and traffic modeling for the North Capitol Street Corridor Planning Study, a key initiative advancing DDOT’s Vision Zero and equity goals. The corridor, which saw nearly 1,600 crashes in two years, is being reimagined to improve safety and connectivity for pedestrians, cyclists, transit riders, and drivers. PSI is developing base and future traffic forecasts, analyzing 45 intersections using Synchro and MWCOG data to evaluate delay, LOS, and multimodal operations for 2031 and 2045 scenarios.

‍

PSI also supports concept development by evaluating design alternatives such as protected bike lanes, bus priority lanes, curbside management zones, and ADA improvements. Our team creates GIS-based layouts, visualizations, and feasibility assessments to guide decision-making and stakeholder engagement. With a focus on complete streets, green infrastructure, and context-sensitive solutions, PSI is helping transform North Capitol Street into a safer, more inclusive, and people-first urban corridor.
