The systemic approach to safety analysis identifies transportation system characteristics or risk factors that are associated with particular crashes. Risk factors can be characteristics such as curve radius, number of travel lanes, shoulder type and width, or form of intersection control in combination with pedestrian and bicycle facilities. CS is a leader in using systemic analysis to identify risk factors and characteristics and guide decision-makers in prioritizing locations for safety treatments.
A significant number of crashes occur on rural/local roads where it is often difficult to isolate high-crash locations. Often the lanes on these roads are narrow, shoulders are absent, the clear zone is nonexistent, pavement markings and signage are worn and/or obsolete, and to compound all this, resources for fixing them are limited or not available. We understand the technical, financial and human resource challenges confronting the local and rural safety communities.
We are leaders in Transportation Safety Planning (TSP), a proactive approach that integrates safety considerations into the transportation planning process at all levels, and we pioneered the concept of “conscious planning” in transportation. Our work led to changes in federal law to mandate safety as a separate planning factor and core funding program. We are experts in quantitative safety planning and engineering, providing quantitative estimates of crash frequency to help agencies plan and prioritize investments.
Transportation-related crashes, injuries and deaths take a tremendous human and economic toll. They also, in many instances, are predictable and preventable. Cambridge Systematics takes a multidisciplinary, multimodal approach that emphasizes the four Es of safety: Engineering, Enforcement, Education and Emergency Response. Our specialties include strategic safety planning, program and project implementation, data collection and analysis, countermeasure selection and prioritization, monitoring, evaluation, training, and communications.
