BACKGROUND/SUMMARY

The City of Berkeley regularly conducts traffic studies to support its goals and objectives. These studies are

initiated through the Capital Improvement Program (CIP) process and in response to community requests. In

addition, the City provides traffic data to partner agencies as needed.

Currently, the City does not have in-house data-collection capabilities; therefore, an on-call traffic data-

collection vendor is essential to deliver this critical service. Requests for traffic surveys are sporadic and vary

seasonally, depending on community inquiries and the phase of CIP projects. While the frequency of these

requests is unpredictable, they are largely driven by public requests and project needs.

II. SCOPE OF SERVICES

The City of Berkeley wishes to hire a consultant to perform traffic speed surveys, volume counts,

classification studies, and other traffic engineering data collection at various citywide locations on an as-

needed basis. The City desires a vendor with specialized experience in data collection and the ability to

provide a variety of solutions using innovative strategies. Under the direct supervision of the City’s Public

Works Transportation Division staff, the consultant will provide on-call traffic survey services to the City.

A. Project Term and Contract Amount: The on-call traffic survey consulting service would be for a three-

year period beginning from July 1st, 2026, and ending June 30th, 2029, with an option for two one-year

extensions. The contract is expected not to exceed approximately $80,000 per year (a total of $640,000 for

the three-year duration and five one-year extensions).

B. Typical Data Collection: Collect traffic data for locations throughout the City of Berkeley as requested, in a

timely manner, performing any or all of the following, according to a schedule to be approved by the

Transportation Division:

1. Perform 24-hour traffic volume counts on an hourly basis in each direction separately, categorized under

13 classifications (Motor Bikes, Cars & Trailers, 2 Axle Long, Buses, 2 Axle 6 Tire, 3 Axle Single, 4

Axle Single, < 5 Axle Double, 5 Axle Double, >6 Axle Double, <6 Axle Multiple, 6 Axle Multiple, >6

Axle Multiple) and also indicate vehicles not classified;

2. Perform 24-hour speed machine counts on an hourly basis in each direction separately, to be grouped

under the following mph groups: 1-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, and 41-999 mph;

3. Perform intersection turning movement counts (motor vehicles, bicycles and pedestrians);

4. Perform “before” and “after” studies in conjunction with rectangular rapid flashing systems

(RRFB)/flashing beacon systems/in-pavement crosswalk lighting systems, per guidelines in Exhibit-B,

attached and other projects at the direction of the City Traffic Engineer.

5. Complete engineering and traffic radar speed surveys in accordance with the California Vehicle Code

(CVC), Section 627 and in dry conditions, to allow legal use of radar for speed enforcement (except

accident data); and

6. Gather roadway segment speeds, observed by use of radar, laser or similar device as needed.

7. Perform other similar traffic counting services.

C. Traffic Counting Standards: Traffic counts shall be conducted in Berkeley as follows:

• 24-Hour Counts: Conduct for at least two full days (48 hours) on Tuesday, Wednesday, or Thursday in

both directions unless otherwise specified by the traffic engineer. Record each direction separately.

• Weekday Count: Conduct on Tuesday, Wednesday, or Thursday. Counts should not be conducted on

Monday or Friday unless otherwise specified by the traffic engineer.

• Weekend Count: Conduct on Saturday and/or Sunday. Saturday counts are preferred when the purpose

is to estimate weekend and recreational activity impacts.

• AM Peak Period Count: Eight consecutive 15-minute intervals for two-hour periods between 7:00 AM

to 9:00 AM unless otherwise specified by the traffic engineer.

• Midday Peak Period Count: Eight consecutive 15-minute intervals for two-hour period between 11:30

AM to 1:30 PM unless otherwise specified by the traffic engineer.

• PM Peak Period Count: Eight consecutive 15-minute intervals for two-hour periods between 4:00 PM

to 6:00 PM unless otherwise specified by the traffic engineer.

• Turning Movement Counts: A minimum of two-hour counts summarized for each turning movement

by 15-minute intervals (estimates based on extrapolation of a shorter counting period are not acceptable).

• Radar Speed Data Collection Survey: The roadway segment speeds will be observed and recorded by

using a radar device to fully satisfy the methodology described in Caltrans Traffic Manual/Manual of

Uniform Traffic Control Devices. Free flow speeds will be measured (at-least 100 observations per

direction) during off-peak hour on typical weekdays (Tuesday through Thursday) not including holidays

or the day before or after a holiday. Typical off-peak weekday hours are 9:00 AM to 11:30 AM, 1:30

PM to 3:30 PM, and 7:00 PM to 10 PM. Data should be provided per attached Exhibit-C “Speed Radar

Survey Sample Sheet” on page 33.

• Exclusion of Holidays, Vacation Period, and Special Events: Data collection must exclude holidays,

vacation periods, and special events, unless otherwise specified by the traffic engineer.

Vendor will avoid collecting data under any abnormal operating conditions until the road segment returns

to normal operating conditions. When data are intended to represent average or typical conditions,

vendor will not collect data during holidays or University vacations or during the first and last two weeks

of the academic semester. Vendor will also avoid data collection during major sports events, concerts,

or other major trip generators. Refer to the schedule for the City of Berkeley and the University

to determine specific dates to avoid.

Information on City holidays is available from City Clerk at (510) 981-6900. Event listing for the City

of Berkeley is available through the visitors’ bureau at (510) 549-7040. Event listings and holidays for

the university are available through University’s Campus Operator at (510) 642-6000.

D. Analysis of Data: The collected data shall be evaluated using the standard analysis method described in the

Caltrans Traffic Manual. Speed data will be studied to determine the average speed, 50th (median) percentile

speed, 85th percentile, 10-mph pace, tabular summation frequency of the speed observed, standard deviation,

cumulative speed distribution curve, date, time started, time ended, weather, direction, and road surface condition.

Traffic data will be summarized into 24-hour, AM peak hour, Midday peak hour and PM peak hour values.

E. Delivery of Data: All traffic data must be provided to the City in electronic forms as well as in hard copy. The

data must be in Adobe Acrobat and Microsoft Excel formats, which can be saved as a database file. The reported

data to the City shall be anonymized (no personally recognizable data) unless directed differently by the City

Traffic Engineer.

F. Documentation: All data and all reports using data must document the source of the data used and the dates,

days of the week, and times of the day of data collection. Any special data collected (e.g., holiday data, event

data) also must specify date, day of week, hours of day, and the nature of the event. Each sheet of data must

clearly show the date of the count and the period of the count, and the location of the count.
