Summary

William Phelps Eno’s 1926 publication, *Fundamentals of Highway Traffic Regulation*, addresses the critical need for standardized, clear, and educational approaches to managing highway traffic. Motivated by the inefficiencies and dangers caused by conflicting local ordinances and the proliferation of complex, unproven technologies, Eno argues that public familiarity with general regulations is the primary key to effective traffic management. He posits that traffic cannot be controlled by elaborate, rigid rules but rather through a standardized code that is short, clear, and reasonable, ensuring it is read and obeyed by the public. The work outlines a comprehensive framework for traffic regulation based on three pillars: Law, Education, and Enforcement. Eno proposes a standardized "Enabling Ordinance" for municipalities, which establishes the Council of National Defense Code as the universal "General Highway Traffic Regulations." This legal structure designates specific roles for a Traffic Director (police enforcement) and a Traffic Engineer (technical planning), separating administrative authority from engineering decisions. The text emphasizes education as the core mechanism for compliance, advocating for the widespread distribution of concise regulation folders to drivers and pedestrians, as well as mandatory instruction in public schools. Eno explicitly rejects the "synchronized block system" of traffic lights, arguing that such complex machinery delays traffic, wastes capacity, and increases danger compared to simple, inexpensive methods. The findings and recommendations focus on the superiority of standardized rules over local tinkering. Eno asserts that the New York City police code, adopted in 1903 and refined through the Council of National Defense, serves as the ideal model for national adoption. He details specific operational rules, such as keeping to the right, proper passing procedures, and the distinction between "regulations" for vehicles and "rules" for pedestrians. The text provides specific definitions for traffic zones (safety, prohibited, restricted, danger) and guides (signs, lines, semaphores). Eno concludes that successful regulation relies on the education of the regulated population rather than the installation of expensive, complicated signal systems. The significance of this work lies in its establishment of a foundational philosophy for traffic engineering: that uniformity, simplicity, and public education are more effective for safety and efficiency than technological complexity or fragmented local laws.
