Traffic Engineering

Some of our recent traffic engineering work includes the following:

Route US 40, Salem County, NJ

This resurfacing and culvert reconstruction project required Arora to prepare striping and signing plans for a four-mile stretch of state highway. Deteriorated signs were identified and replaced while new signs were installed as needed. An intensive signing and striping package was developed to alert motorists to, and safely guide them through, a 90-degree turn in the center of town. This work was made more critical by a need to account for a high percentage of trucks in the highway traffic flow.

State Route 39, Linglestown Road, Lower Paxton Township, PA

Lower Paxton Township and Pennsylvania Department of Transportation hired Arora to plan and design this traffic calming project to enhance the transportation through the corridor and improve conditions for pedestrians and bicyclists along the state roadway, which is Linglestown's main street. The design includes two new modern roundabouts, intersection neckdowns, chicanes, center island medians, and raised crosswalks. A comprehensive urban design scheme was planned for the streetscape to enhance the historic aspects of the Village of Linglestown.

Route 31/Route 57, Warren County, NJ

This planning-based project required Arora to apply the Highway Capacity Manual and Synchro analyses to various improvement alternatives at an existing signalized intersection. These tools were used to establish available capacity and level of service designations for the alternative assessment portion of the project. A roundabout alternative was also developed and its short and long-term operational characteristics were identified using the RODEL software program.

Route 73, Burlington County, NJ

This highway and bridge reconstruction project had a significant traffic engineering component. An existing highway traffic signal was removed and replaced with a state-of-the-art design and operation. In addition, two new traffic signal designs were accomplished for two newly created highway ramp locations. The signing was upgraded throughout the project area to include newly designed ground-mounted directional/destination signs and new overhead cantilever signs. Synchro analyses were performed to establish and support the intersection configurations and to establish the revised signal timings and operations included in the existing Route 73 corridor traffic management system. Traffic control and stage construction plans and temporary traffic signal plans were prepared for the overall construction project and the numerous detours that were implemented.

Deerfield Associates, Burlington County, NJ

This right-of-way modification project arose as the direct result of the Route 73 project. New Jersey Department of Transportation needed to establish a temporary construction easement within private property while a retaining wall was being built. The implementation of such an easement would occur on land being used for resident parking within an apartment complex. Arora conducted parking counts and a site parking inventory to produce a modified parking plan that would allow a retaining wall to be constructed in phases while minimizing the impacts to the available parking supply and configuration.
