Transit Operations: Comprehensive Guidelines for Project Impact Analysis for the Culver city

Transit Operations Guidelines for Development Projects

Introduction

When planning new development projects, it is crucial to address their potential impacts on existing transit systems to ensure that transportation infrastructure can accommodate increased demand and operate efficiently. The Culver City's guidelines for transit operations, effective from July 13, 2020, outline comprehensive criteria for evaluating and mitigating these impacts. This document details the procedures that applicants must follow to assess and address the effects of their projects on local and regional transit systems.

Consultation with Transit Operators

The first step for applicants is to engage with both regional and local fixed-route transit operators that service the project area. This engagement includes obtaining and analyzing data from automated vehicle location systems, where available. The purpose of this consultation is to assess how the project might influence transit services and to identify necessary improvements. Transit operators will review the project's potential impacts and provide feedback on needed service or capital enhancements.

Documentation Requirements

Applicants must meticulously document the anticipated impacts of their projects on various aspects of transit services. This includes evaluating the following:

• Transit Capacity: Determine how the project will affect the capacity of transit routes serving the site. This involves estimating the number of new transit trips generated and assessing whether existing transit routes and stops can handle the increased demand.

• Headway: Evaluate potential changes in headway—the interval between vehicles on a transit route. Changes in headway can impact service frequency and reliability.

• Travel Time: Assess the impact on travel times between key time points on the transit route. This includes evaluating the time before and after the project's designated stop to understand how the project affects overall travel time.

• Delay: Document potential delays experienced by transit vehicles due to the project. This includes analyzing the impact on travel time and identifying any additional delays caused by increased vehicular traffic or changes in traffic patterns.

• Service Reliability: Examine how the project affects the reliability of fixed-route transit services, focusing on on-time performance and adherence to schedules.

Methodology for Impact Assessment

Travel Demand and Capacity by Route

To estimate the impact on transit routes, the applicant should calculate the number of new transit trips resulting from the project based on trip generation estimates and mode split data. This process involves:

1. Estimating New Transit Trips: Using trip generation data, estimate how many additional trips the project will generate for transit services.

2. Assigning Trips: Allocate these new trips to specific transit routes and stops serving the project site.

3. Capacity Assessment: Evaluate whether the existing capacity of these routes and stops can accommodate the increased demand.

Transit Delay Analysis

The Transportation Department will assess whether the project will significantly delay transit services. This assessment will be based on quantitative or qualitative criteria, including:

1. Thresholds for Analysis: Projects generating more than 300 vehicle trips during the PM peak hour or over 3,000 daily vehicle trips must undergo a detailed transit delay analysis.

2. Delay Analysis Criteria: If a project results in delays greater than half the headway for surface transit lines, the Transportation Department may mandate additional measures. The analysis may include:

   • Transit Service Headways: Examine the frequency of transit service and current ridership levels.
   • Trip Origins and Destinations: Consider the starting and ending points of transit trips.
   • Alternative Modes: Evaluate the availability of other transportation options.
   • Competitive Factors: Assess how the project impacts competition with private vehicles and for-hire services.

3. Approved Methodologies: Applicants can propose methodologies for delay estimation, subject to Transportation Department approval. Acceptable methods include:

   • Traffic Congestion Delay: Measure delays caused by congestion at intersections and along transit routes.
   • Transit Reentry Delay: Evaluate the time required for buses to reenter traffic flow from stops.
   • Passenger Boarding Delay: Calculate delays related to passenger boarding and alighting at transit stops.

   Additionally, applicants may use tools such as the Transit Research Board’s Transit Capacity and Quality of Service Manual for calculations.

Assessment of Hazardous Conditions

The applicant must evaluate the potential for hazardous conditions arising from the project’s vehicular traffic and design features. This assessment should include:

1. Vehicle Trip Analysis: Analyze the number, type, and speed of vehicle trips generated by the project, including their interaction with transit lanes and stops.

2. Design Features: Assess how project design elements (e.g., curb cuts, roadway dimensions) impact transit operations.

3. Sightlines and Obstructions: Evaluate any physical obstructions or sightline issues that may affect transit vehicle operations or safety.

4. Examples of Hazardous Conditions:

   • Projects that significantly increase vehicle trips near or across transit-only lanes or facilities.
   • Projects with physical obstructions that obstruct sightlines between motorists and transit vehicles.
   • Projects unable to accommodate all vehicle trips, leading to queues on transit lanes or near transit facilities.

Improvement Measures

If the project is found to significantly delay public transit or create hazardous conditions, the applicant must collaborate with the Transportation Department to develop and implement improvement measures. Potential measures include:

• Design Revisions: Modify project design to eliminate hazardous conditions.
• Transit-Only Lanes: Establish new transit-only lanes or contribute financially to their creation.
• Queue Jump/Bypass Lanes: Implement lanes that allow transit vehicles to bypass congestion.
• Transit Stop Optimization: Improve the location and layout of transit stops to enhance efficiency.
• Extended Transit Zones: Increase the capacity of transit zones to accommodate more vehicles.
• Transit Capacity Enhancement: Support efforts to expand the capacity of local transit systems.
• Construction Contributions: Contribute to the development or enhancement of transit stations and centers.
• Transit Flow Projects: Support initiatives that improve transit flow, such as priority signal systems and dedicated bus lanes.
• Incentives for Transit Use: Fund projects that offer real-time arrival information and other incentives to encourage transit use.

Reporting

The applicant must provide a comprehensive reporting program to the Culver City detailing the implementation of adopted transit improvement measures. This report should outline the specific measures taken, their effectiveness, and any additional recommendations for future improvements.

Effective transit planning and mitigation are essential for ensuring that new projects do not adversely impact existing transit services. By following these guidelines, applicants can help maintain efficient, reliable, and safe transit operations while accommodating new development. The collaboration between project developers and transit operators, along with the implementation of appropriate improvement measures, will contribute to the overall success of the transportation infrastructure in the Culver City.
