I1−3: Full−Time State Police Positions Assigned to Safety and Construction Issues


In Maryland, a State Police Liaison Officer is available to provide valuable input on a number of highway safety related issues including work zones. The State Police and the Maryland State Highway Administration (MDSHA) understand each other's roles and work together as a team to solve mutual safety problems. The Liaison Officer has been working on location with MDSHA for over 10 years.

The New Jersey Department of Transportation (NJDOT) and the New Jersey State Police (NJSP) developed a unique construction unit consisting of NJSP Troopers to assist NJDOT Resident Engineers in monitoring and enforcement of the approved traffic control plans (TCPs). The unit was activated in 1994 to increase the performance level of law enforcement services relating to work zone safety and to establish consistency in enforcement of TCPs on a statewide basis. Troopers assigned to the NJSP Construction Unit receive specific work zone safety training.


MDSHA and the Maryland State Police realized that Maryland's highway system would operate more efficiently and safely if both agencies worked as a team. A number of highway safety issues: 1) work zone traffic control safety concerns, 2) freeway traffic incident management, 3) special events, and 4) seasonal traffic management responsibilities, led to the adoption of this policy.

The NJDOT and NJSP realized the need to increase the level of performance of law enforcement personnel in work zones and provide enforcement consistency on a statewide basis.


The primary benefits being realized from this best practice include: 1) improved highway safety, 2) immediate action on highway safety issues, 3) improved operations between State Police and MDSHA/DOT personnel, 4) uniformity in the implementation of TCPs, and 5) increased level of safety for workers and travelers.
