CTC knows signalization. We possess deep expertise in the interconnection of traffic signal operations with railroad signal systems or railroad preemption. We employ the industry’s leading preemption experts and have designed innovative products to further safety at preempted highway-rail grade crossings all across North America.
In fact, our experts continue to contribute improvements to these standards:
- Manual on Uniform Traffic Control Devices (MUTCD)
- The American Railway Engineering and Maintenance-of-Way Association’s (AREMA) Communication & Signal Manual of Recommended Practice
- Institute of Transportation Engineers’ (ITE) recommended practice for Preemption of Traffic Signals Near Railroad Crossings
- Federal Highway Administration’s (FHWA) Grade Crossing Handbook
- Texas Department of Transportation’s (DOT) Guide for Determining Time Requirements for Traffic Signal Preemption at Highway-Rail Grade Crossings
- National Cooperative Highway Research Program (NCHRP) Transportation Research Board’s Report 3-66, Traffic Signal State Transition Logic Using Enhanced Sensor Information
- IEEE 1570 protocol for Interconnection of Traffic Signals and Highway-Rail Grade Crossing Warning Systems
Our process for reviewing highway-rail grade crossings interconnected with traffic signals is methodical and includes conformance assessment with established requirements by the FHWA, Federal Railroad Administration (FRA), ITE and AREMA. This type of review is further reinforced by FRA Safety Advisory 2010-02 and FRA Technical Bulletin S-12-01.
We’ve successfully used our methodology to review over 2,500 preempted highway-rail grade crossings and to implement corrections that mitigate risk.
We’re serious about safety. For our clients. For our employees. For the traveling public.
