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 »
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 »
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 »
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 »
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 »
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 (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 »
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 »
Outreach interviews should be conducted with procurement and contracts representatives from large transit agencies and Departments of Transportation (DOTs) throughout the country to inform the development of recommendations regarding best practice construction contracting processes for large and small construction projects, including identification of contracting vehicles. A review of the standard terms and conditions ...more »
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 »
Successive recent federal transportation re-authorizations have reshaped various Federal transportation funding programs and created new ones. In today's fiscally constrained environment where investment needs exceed available funding, it is paramount to ensure that New Jersey is maximizing it's draw down of available Federal Funds. This research study will: 1) Inventory/document all available Federal transportation ...more »
Transportation technologies are changing rapidly. Changes in wireless networks, the Internet, smartphone capabilities and other advances in technology have ushered in new shared use mobility options including: car-sharing; ride-hailing services like Uber and Lyft; bike-sharing; a new generation of ride-sharing; flexible commercial delivery; and others. Electric vehicle adoption is accelerating; and automated vehicle technology ...more »
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 »
New Jersey is part of the nationwide 511 traveler information system that provides real-time traffic information to the general public. NJDOT can provide travelers with real-time travel time and event information on NJ highways with probe travel time data from TRANSMIT, Inrix, and HERE and incidents and special events data from OpenReach. Furthermore, real-time XML data feeds can be accessed by public and private sector ...more »
