Introduction

Todd Center Shopping Center is a 242,387 square foot community shopping center located in
the Coliseum Central Business Improvement District of Hampton, Virginia. The 27-acre property
fronts Todds Lane east of Aberdeen Road. The shopping center is anchored by large retailers
such as Big Lots, Grand Furniture, Hancock Fabrics, Lumber Liquidators, Northern Tool &
Equipment, and OfficeMax.

Todd Shopping Center, LLC proposes to redevelop the northwest corner of the site with the E-
Commerce Center of Hampton, a 94,936 square foot (sf) building offering office, retail, and
mini-warehouse uses. The three uses are envisioned to function in concert with each other
(storing, internet selling, and shipping) as well as independently. The building space is designed
for 4,650 sf of retail for shopping such as a FedEx or UPS counter, 19,337 sf of office space, and
70,949 sf of storage space divided into 429 units.

The City of Hampton requires a traffic impact study for the site in order to assess the potential
impact the land use will have on the existing transportation network.

Background Information

The intersections included in the study area are Mercury Boulevard and Aberdeen Road, and
Todds Lane and Aberdeen Road (see Figure 1), which are both signalized. The shopping center has
multiple driveways on both Todds Lane and on Aberdeen Road. The proposed plan consolidates
some of the driveways such that two driveways, one on Todds Lane and one on Aberdeen Road,
serve the parking area of the study site.

Study Area Roadways

  Todds Lane

  Todds Lane is a four-lane minor arterial north of the study site. The posted speed limit in the
  vicinity of the site is 40 miles per hour (mph). The corridor includes retail, commercial,
  residential, and civic land uses. Bethel Church is directly across the street; however, there are not
  any driveways from the church parking lot on Todds Lane near the study site.

  Aberdeen Road

  Aberdeen Road is a four-lane minor arterial west of the study site. It has a posted speed limit of
  35 mph. Aberdeen Road runs north-south and intersects with Todds Lane and Mercury
  Boulevard. This is the only block Aberdeen Road in the vicinity that serves commercial land uses.
  North and south it is mostly residential.

Mercury Boulevard

  Mercury Boulevard is an eight-lane divided principal arterial roadway running east-west through
  Hampton, with a speed limit of 45 mph. There are left and right turn lanes at signalized
  intersections along this corridor. It is heavily developed with commercial land uses in the vicinity
  of the study site.

  Figure 1, presents the project location and the street network serving the site. Figure 2 shows
  the existing lane configurations at the intersections of Todds Lane and Aberdeen Road and
  Mercury Boulevard and Aberdeen Road.

Proposed Development

The E-Commerce Center of Hampton consists of a 94,936 square foot (sf) building offering office,
retail, and mini-warehouse uses. The building space is designed for 3,491 sf of retail for shopping
such as a FedEx or UPS counter, 17,785 sf of office space, and 63,978 sf of storage space divided into
429 units. Two entrances are proposed: one onto Todds Lane and another onto Aberdeen Road, see
Figure 3 for a copy of the site plan. The driveway on Todds Lane is slightly more than 200 feet east of
the Aberdeen Road intersection. The driveway on Aberdeen Road is approximately 360’ north of
Mercury Boulevard and 470’ south of Todds Lane; it generally aligns with Edgewood Drive.

The three uses are envisioned to function in concert with each other (storing, internet selling,
and shipping). As a result of the description of the businesses, the City of Hampton requested
an estimate of truck traffic coming into and out of the site. Truck trip estimates were prepared
referencing the National Cooperative Highway Research Program (NCHRP) Synthesis 298 Truck
Trip Generation Data, 2001, and the ITE Trip Generation Handbook, 2004, see Table 1. In
recognition of the synergy associated with the land uses as described, the truck count was
adjusted by increasing the single-unit trucks and decreasing the combination trucks (tractor
trailer trucks) for the site.

Analysis of Existing Conditions

Capacity Analysis

Turning movement counts were provided by the City of Hampton. The counts for Mercury
Boulevard and Aberdeen Road were taken on May 1, 2012 from 6:30 – 8:30 AM, 10:30 AM – 2:00
PM, 3:30 – 5:30 PM, and 6:30 – 7:30 PM. The counts for Todds Lane and Aberdeen Road were taken
on May 3, 2012 from 7:00 – 9:00 AM, 11:00 AM – 12:00 PM, 1:00 – 2:30 PM, 3:30 – 6:00 PM, and
6:30 – 7:30 PM.

To establish traffic volumes for the 2015 No-Build scenario, the existing turning movement counts
provided by the City had a five percent growth rate applied. The resulting values are presented in
Figures 4 and 5 as the “background” volume.

Capacity Analysis results are expressed in terms of Level of Service (LOS). LOS is a qualitative
measurement of traffic operations. It is translated from a measure of delay to drivers in units of
time, seconds per vehicle. The Transportation Research Board’s Highway Capacity Manual (HCM)
defines six levels of service for intersections with LOS “A” representing operating conditions with
minimal constraints on traffic movements and LOS “F” representing extremely congested operating
conditions. LOS “D” is considered the threshold of acceptable operations for an overall intersection.
Exhibit 18-4 of the HCM gives the criteria for signal controlled intersections.

HCM Exhibit 18-4: Level of Service Criteria

Synchro 8.0 was the software tool used in determining the delay, capacity and corresponding level
of service of the study intersections. The results indicate that both the intersections operate at an
overall LOS “D” or better. The delay and LOS information calculated in the analysis are presented in
Tables 2 and 3.

Existing Queue Conditions

SimTraffic was used to estimate the queues at the signalized intersections. SimTraffic uses a hot
spot, 20 feet in length at the top of each lane or approach just prior to the adjacent intersection to
help to identify possible queuing or spillback issues on adjacent intersections. If a vehicle is in that
hot spot and is traveling less than 10 mph, it is assumed to be queued. The queuing and blocking
reports are a result of the average of ten runs.

Table 4 presents the estimate queue lengths for the existing AM and PM hours. Results and
observations of queuing simulations show that the intersections operate within their storage
capacities.

 volumes were increased by 1 percent per year for each of the turning movements. The 2020 AM and PM
 No-Build Volumes are presented in Figures 7 and 8, respectively, as the “background” volume.

 Synchro 8.0 was the software tool used in determining the delay, capacity and corresponding level
 of service of the study intersections. The results indicate that both intersections operate at an
 overall LOS D or better. Tables 5 and 6 present the delay and LOS information calculated in the
 analysis for this condition.

Analysis of Build Conditions

Trip Generation

Traffic that may be generated by the proposed redevelopment was established using equations
and rates available through the Institute of Transportation Engineer’s (ITE) Trip Generation, 9th
Edition.

Trip generation for the site was prepared for each individual land use. ITE provides information
for copy, print, and express ship stores (Land Use Code 920), general office buildings (Land Use
Code 710), and mini-warehouses (Land Use Code 151).

Having a mix of land uses in close proximity to each other encourages one trip to the
development combining multiple destinations. The residential and retail component trips are
combined where the origin and destination are within the area and do not use the arterial
street system. Reductions are made to the first stage of the trip generation to calculate the
traffic which leaves the site. This adjustment is termed “Internal Capture.” The internal capture
reductions were taken in accordance to the ITE Trip Generation Handbook.

The trip generation per land use, including internal trips, may be found in Table 8 below.

Trip Distribution

Trip distribution was based on the existing traffic patterns and the understanding of the land
uses within the surrounding area.

The site traffic distribution is 20% to/from the east, 15% to/from the west, 5% to the north, and
60% to/from the south. Traffic distribution is expected to be consistent throughout the day, see
Figure 4.

Summary and Conclusions

This study performed an evaluation of the No Build and Build scenarios for 2015 and a horizon
year of 2020, AM and PM Peak Hours. The study intersections included in the analyses were
Todds Lane and Aberdeen Road and Mercury Boulevard and Aberdeen Road.

The 2015 and 2020 No Build conditions indicate that the study intersections function overall at
acceptable levels of service (LOS) of “C” in the morning peak hours and “D” in the afternoon.
Some of the movements fall into LOS “E” or “F”; however the volume to capacity (V/C) ratio is
less than one. The LOS in these situations are typically a result of long wait times due to cycle
length. This condition is typically found to be acceptable under these circumstances. Another
measure of effectiveness is the estimated queue length. The queue lengths fall within the
storage capacity of the turn lanes.

The site is estimated to generate 732 daily trips with 57 trips during the morning peak hour and
70 trips during the evening peak hour. Of the 732 trips, 54 truck trips are estimated to access
the site on a daily basis, which is equal to 27 trucks coming into and out of the site daily.

The results show that once the proposed project is built, a slight increase in delay at each
intersection under each scenario can be expected. There is an anticipated change in LOS from
“D” to “E” during the 2020 PM Peak Hour between the No-Build and Build scenarios. A 4%
increase in delay crosses the threshold from “D” to “E” for the overall intersection. The
additional southbound left turn volume from the site in combination of the 1% per year growth
in background traffic shows many of the movements at the intersection pushing close to the
capacity of the intersection.

A review of the simulation modelling and the calculated queue lengths indicate that the
intersection clears during the critical peak hour and that the queue lengths do not spill back
into upstream intersections.

In conclusion, the results of the analyses indicate that the development of the site as proposed
will have modest impact on the intersections within the study area.
