This document provides a detailed outline of the Local Transportation Analysis (LTA) for projects in Hayward, specifying when it is required, its sections, and the specific analyses to be performed. Here are the highlights:
1. Purpose and Scope of LTA
- Objective: The LTA ensures safe multimodal operations and site access for new developments.
- Applicability: Required for projects that fail the CEQA screen and, selectively, for projects that pass it but may still need additional operational analyses.
- Sections: The LTA consists of three main sections: Vehicle Operations Analysis, Multimodal Operations Analysis, and Site Plan Assessment.
2. Vehicle Operations Analysis
- Subsections and Analyses:
- Trip Generation, Distribution, & Assignment: Assesses trip generation using ITE Trip Generation Handbook standards, with additional assumptions as needed.
- Intersection Operations: Uses approved methodologies (e.g., Synchro) to evaluate Level of Service (LOS) for project intersections, with defined goals for minimizing delay impacts.
- Queueing Analysis: Assesses queue lengths to ensure they do not interfere with traffic flow or access points.
- Traffic Signal Warrants: Evaluates the need for traffic signals at unsignalized intersections based on established MUTCD warrants.
- All-way Stop Analysis: Required if deficiencies are identified at unsignalized intersections.
- Site Access/Egress: Evaluates driveway locations, configurations, and safety.
- Alameda CTC Congestion Management Program (CMP): For projects generating 100+ PM peak trips, a CMP analysis assesses LOS for all travel modes.
3. Multimodal Operations Analysis
- Subsections and Focus Areas:
- Planned Bicycle and Pedestrian Infrastructure: Considers existing and planned facilities along project frontages, requiring conformance with city plans (e.g., high-visibility crosswalks, ADA ramps).
- Bicyclist and Pedestrian Behavior & Travel Patterns: Utilizes 5-year collision data and observational studies for insights into travel behavior.
- Pedestrian Crossing Safety: Evaluates safety at uncontrolled crossings and proposes improvements as per FHWA guidelines.
- Pedestrian Lighting: Assesses adequacy of lighting for pedestrian safety.
- Bus Stop Locations and Amenities: Reviews transit stop conditions and amenities, incorporating improvements if feasible.
4. Site Plan Assessment
- Internal Site Design Standards:
- Parking Stall Dimensions and Layout: Must comply with city code specifications for dimensions and design standards.
- Driveway Sight Distance: Ensures that sight triangles meet safety standards.
- Internal Bicycle and Pedestrian Circulation: Promotes accessible paths within the site that connect with public facilities.
- Fire Safety and Solid Waste Geometric Design: Ensures access for emergency and service vehicles.
- Bicycle Parking: Requires secure, accessible parking with design adhering to Association of Pedestrian and Bicycle Professionals (APBP) standards, including space for various bike types and appropriate lighting.
Each section of the LTA aligns with city policies, prioritizing multimodal accessibility and safety while supporting project impacts on local transportation infrastructure.

Local Transportation Analysis (LTA) Template for City of Hayward Projects
The Local Transportation Analysis (LTA) is required as part of the Transportation Impact Assessment (TIA) for any project that does not meet the California Environmental Quality Act (CEQA) screening thresholds, or for specific projects needing additional local operational or site access analysis as deemed necessary by the City of Hayward. The LTA aims to ensure safe multimodal operations, traffic flow, and site accessibility, covering vehicular, multimodal, and site plan assessments. The LTA template outlined below guides applicants and consultants through the required sections and analyses. Each project’s specific requirements will be determined as part of the Transportation Analysis scope of work, and the City may require additional analyses beyond those listed here.
1. Vehicular Operations Analysis
1.1 Trip Generation, Distribution, & Assignment
- Threshold: Detailed analysis is required if peak hour trips exceed 50 or at the City’s discretion.
- Methodology: Use the latest ITE Trip Generation Handbook unless an alternative is approved by the City.
- Components: Include supported assumptions for pass-by trips, occupancy rates, and distribution splits. City staff will verify data such as square footage and use types of current and proposed development.
1.2 Intersection Operations
- Selection: City-approved intersections based on the Traffic Scoping Memorandum, including all project access points.
- Methodology: Typically uses the Highway Capacity Manual (HCM) standards, with Synchro software for analysis.
- Analysis Periods: AM (6-9 AM) and PM (3-7 PM) peaks; additional periods may be required by the City.
1.3 Queueing Analysis
- Requirements: Ensure that queues do not exceed turn bay/lane capacity, encroach on neighboring property frontage, or extend onto public roads.
- Goals: Address and recommend improvements for queue deficiencies based on average and 95th percentile queue lengths.
1.4 Traffic Signal Warrants
- Criteria: Include studies if operational issues exist at unsignalized intersections, referencing MUTCD warrants (e.g., volume thresholds, pedestrian/bicycle volume, crash history).
1.5 All-Way Stop Analysis
- Requirements: Perform an all-way stop warrant analysis for any identified operational deficiencies at unsignalized intersections.
1.6 Site Access/Egress
- Evaluation: Ensure access points are safe, well-marked, and minimize conflicts with pedestrians and cyclists. Follow City guidance for driveway alignment, proximity, and consolidation.
1.7 Alameda CTC Congestion Management Program Analysis
- Threshold: Required if the project generates 100 or more PM peak hour trips. Analysis includes LOS for roadway segments and multimodal network reviews.
