City of Irvine Strengthens Bike Network with First Class IV Protected Bikeway
The City of Irvine took an important step in expanding opportunities for cycling with the opening of its first Class IV Protected Bikeway Tuesday, November 19.
City leaders, staff, and community members came together to celebrate the opening, which included the first official ride on the 1.25-mile bikeway on Cadence between Radial and Chinon. Led by Tony Cruz, an Assistant Transportation Analyst in the City’s Public Works & Sustainability Department who is also a former pro cyclist and Olympian, the celebratory ride included City leaders, Cadence Park School student and Irvine Youth Action Team member Shivraj Chudasama, and residents.
Irvine has an extensive bike network with 113.24 miles of off-street bikeway trails and 286.42 lane miles of on-street bikeways. With a physical barrier separating drivers and cyclists, the Class IV Protected Bikeway will enhance the network by providing a safe option for getting around on a bike.
“This protected bikeway is an important step in our commitment to maintaining a livable, safe, balanced community while working to achieve our sustainability goals,” said Mayor Farrah N. Khan. “I am looking forward to seeing this bikeway connect our community, making it easier for children and families to get to school, parks, and as we continue building the Great Park, enjoy all that it has to offer — without needing a car.”
All bicycle types are allowed to ride in the Class IV bikeway, including e-bikes of all classes. At the event, the City also unveiled its first electric street sweeper, a 2024 Dulevo D-Zero Plus sweeper known as “Evie.” This innovative addition to the fleet will keep the bikeway clean and well-maintained, while preserving the environment.
With a top speed of 20 mph, Evie will predominantly be used to sweep trails. As the City builds more Class IV bikeways, it is estimated that the electric sweeper will save approximately 18 metric tons of carbon emissions over a year — the equivalent of taking 4.2 gas-powered vehicles off City streets.
Together, the Class IV protected bikeway and the electric street sweeper create a more bike-friendly community and help the City achieve its ambitious emissions reduction goals outlined in its Climate Action and Adaptation Plan.
爾灣市在建設宜居、安全和永續社區方面又邁出了一大步。2024年11月19日，爾灣市首條 IV 級保護自行車道正式啟用，這是一段長達 1.25 英里 的自行車專用車道，位於 Radial 和 Chinon 之間的 Cadence 上，透過實體屏障實現騎行者與駕駛員的完全隔離，為市民提供更加安全的出行選擇。
啟用慶典與首次騎行
當日啟用儀式在熱烈的社區氛圍中舉行，由市公共工程與永續發展部助理交通分析師、前職業自行車選手暨奧運會選手托尼·克魯茲（Tony Cruz）主持。市長法拉·N·汗（Farrah N. Khan）、Cadence Park 學校學生、爾灣青年行動小組成員 Shivraj Chudasama，以及眾多居民共同參與，並進行了自行車道上的首次正式騎行，體驗全新基礎設施的便捷與安全。
「這條受保護的自行車道是我們致力於打造宜居、安全、平衡社區，同時實現永續目標的重要里程碑，」市長法拉·N·汗表示。她強調，這條車道將促進社區連結，讓兒童和家庭更容易到達學校、公園，並在持續建設大公園的過程中享受自行車出行的便利。
為何選擇 IV 級保護自行車道？
IV 級保護自行車道是爾灣市廣泛自行車網絡的最新亮點，該網絡已涵蓋 113.24 英里的街外自行車道 和 286.42 車道英里的街內自行車道。這類自行車道透過物理屏障（如柔性立柱或停車位隔離）將騎行者與其他交通完全分開，適用於所有類型的自行車，包括電動自行車，為市民提供更加安全的騎行體驗。
「Evie」電動清掃機亮相 助力減排目標
爾灣市還在此次活動中推出了首款電動街道清潔機——2024 年 Dulevo D-Zero Plus 清掃機，暱稱「Evie」。這款清掃機設計最高時速為 20 英里/小時，專為清潔自行車道和街道而打造，預計每年將減少約 18 噸碳排放，相當於街道上減少 4.2 輛汽油動力車輛。
「Evie」的投入使用體現了爾灣市在保護環境、提升基礎設施維護效率方面的創新精神。隨著更多 IV 級保護自行車道的建設，爾灣將進一步推進其氣候行動和適應計劃中制定的減排目標，實現更加永續的城市發展願景。
IV 級保護自行車道的啟用與新技術的融入，不僅為爾灣市民帶來更安全的出行選擇，也樹立了推動綠色交通的城市典範。
爾灣邁向氣候智能型城市的願景
IV 級保護自行車道的建設，不僅為市民提供了更加安全、便捷的出行選擇，也助力實現了爾灣市在其氣候行動和適應計劃（CAAP）中設定的宏偉目標。
自 2021 年以來，爾灣市著手制定首個 CAAP，規劃具雄心且可實現的減排目標。該計劃涵蓋市政運營與社區層面的多項氣候適應與溫室氣體減排措施，致力於打造一座真正的氣候智能型城市。通過這些努力，爾灣市將在 2030 年及以後，朝著積極的減排目標邁進，進一步鞏固其在奧蘭治縣的氣候領導地位。
