Virtual Reality State Highway System (VRSHS)

There are many different companies that use various types of road mapping hardware/software for their respective purposes. This technology could be utilized for multiple purposes that would benefit both the DOT and the public. All of these purposes would be achieved by the creation of a Virtual Reality State Highway System (VRSHS). I propose that the NJDOT contract with one of these companies to utilize their technology, ...more »

Enhancing Safety and Durability of Concrete Structures Using Engineered Cementitious Composites

Several months ago, the main span of the Florida International University (FIU) pedestrian bridge collapsed during construction. The bridge was designed as a signature structure in the City. Accelerated Bridge Construction (ABC) technique was implemented in the construction. An investigation on the collapse is being led by the NTSB and supported by multiple agencies, such as FHWA. Preliminary investigation reports indicate ...more »

Design of Stay-in-Place UHPC Formwork for Accelerated Bridge Construction

Recently, ultra-high-performance concrete (UHPC) has been introduced which has much higher mechanical properties and toughness than high-performance concrete (HPC). UHPC is typically a micro-mortar reinforced with micro fibers resulting in extremely impermeable and crack-resistant material. Such material can be used to produce precast panels that can be assembled on-site as stay-in-place (SIP) panels for the construction ...more »

Development of Cost-Effective Polyethene Fiber Reinforced UHPC for Infrastructure Rehabilitation

Constructability, strength, ductility and durability are crucial properties for development of materials for infrastructure rehabilitation. Constructability should allow ease of mixing, placing, and curing of rehabilitation application. High-strength can facilitate the small volume of repair materials to provide enough strength falling in safety margins (particularly in compression) of structures. High ductility can prevent ...more »

Enhancing the fatigue resistance of welded joints in steel structures

While steel girders have a lot of advantages and are widely used in transportation infrastructure, welded joints in the steel girders under cyclic loading are subjected to fatigue cracks, which can significantly compromise the service life of the steel girders. Recently, two innovative approaches have been presented to improve the fatigue resistance of welded joints. The first approach is to use locally-thickened steel ...more »

Innovative HPFRCC-steel composite girder under combined mechanical and environmental loadings

Concrete-steel composite girders combine the advantages of concrete and steel and have been used in a number of bridges worldwide. However, concrete cracking and shear connector damages affect the long-term durability of the conventional concrete-steel composite girders. In recent years, high-performance fiber-reinforced cementitious composites (HPFRCC) that have high mechanical strength, crack resistance, workability, ...more »

Unmanned Aerial Vehicles for Structural Health Monitoring in Operation and Extreme Events

Unmanned aerial vehicles (UAVs) have shown great potential for health monitoring of civil infrastructure. UAV provides a platform to seamlessly integrate advanced sensing, communication, and machine learning for structural health monitoring. For example, UAV carrying a camera has been used to image damages in bridges, in particular, for the locations where people have limited access, such as the bottom of the bridge deck ...more »

Improved Decision Making for Effective Winter Maintenance

Weather events such as precipitation, snow, and extreme temperatures reduce roadway capacity and escalate crash risk due to slick pavement. Currently NJDOT uses weather forecast and Road Weather Information System (RWIS) to make decisions on anti-icing and deicing treatments. The maintenance of RWIS stations are costly and only limited stations exist in NJ. However, road surface temperature and condition may vary significantly ...more »

Grade Crossing Safety

Research will be conducted on counter measures by incident and grade crossing type that have been implemented and successfully reduced crashes and incidents at grade crossings throughout the country. Working with the NJ TRANSIT Planning and Engineering Departments, a list and map of grade crossings that are used by NJ TRANSIT will be provided to support this work. Statistical and other safety data provided by NJ TRANSIT ...more »

Integrating Real-Time Traffic Data with NJDOT Signal PerformanceMeasurement System

The NJDOT is currently piloting the FHWA ATSPM (Advanced Traffic Signal Performance Measure) system with modifications made to take in the existing NJDOT InSync and SCATS controller data. The modifications addressed the limitations of the FHWA version of ATSPM system of only accepting data from high-resolution traffic signal controllers. However, there are still a significant number of existing NJDOT low-resolution signals ...more »
