Penelitian ini merupakan penelitian deskriptif kuantitatif. Teknik Pengumpulan data menggunakan observasi lapangan dan dokumentasi. Analisis data menggunakan Manual Kapasitas Jalan Indonesia 1997. Hasil analisis data digunakan untuk menentukan solusi mengatasi kemacetan di jalan Kyai Mojo, Surakarta. Hasil penelitian menunjukkan bahwa tingkat layanan jalan Kyai Mojo tahun 2019 berdasarkan Manual Kapasitas Jalan Indonesia 1997 berada pada tingkat layanan E. Tingkat layanan E berarti kondisi arus tidak stabil, kapasitas penuh, dan terkadang kecepatan terhenti. Manajemen lalu lintas untuk mengurangi kemacetan di jalan Kyai Mojo yaituTransport Demand Management (TDM) dengan cara membuat jalur khusus kendaraan tak bermotor diluar jalur lalu lintas selebar 2 meter dan memasang rambu lalu lintas berupa traffic light.","PeriodicalId":416376,"journal":{"name":"Indonesian Journal Of Civil Engineering Education","volume":"737 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122948499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
